Tech Tips – Residential IHT (w/ External Expansion Tank) Oil Maintenance
Oil Maintenance Procedures for Residential IHT units with External Expansion Tank
Designed to be trouble-free
Normally the Residential IHT (K46), which is featured in many tractor & rider models, does not require any servicing for the life of the vehicle. However, if there is a desire to check or replace oil, it may be necessary to remove the transaxle from the vehicle to access the black cap located under the pulley and fan. Due to the design of our units.
Maintenance Overview
First, remove the transaxle from the vehicle following OEM instructions. After placing the transaxle on a bench surface remove the fan & pulley and pry open the black cap and remove magnet (see Fig #1). Invert transaxle to allow the oil to drain from case through the port under the black cap.
Tuff Torq K46 Oil Maintenance – Figure 1
Refill transmission case with oil through same port to near top of the case. Tuff Torq® recommends refilling transmission with Tuff Torq® hydrostatic oil, available from our service and aftermarket department.
Reinstall magnet & cap. While reinstalling the fan & pulley on drive shaft be sure to place all components in the same order as they were removed.
In heavy usage applications, oil changing is recommended after the 1st 50 hours of operation and every 200 hours, thereafter. The filter should never require changing unless the transaxle is removed from the tractor or rider and opened for repairs.
Finally, after purging the transaxle of air, add additional oil through tank opening (under vent valve) to the recommended oil level. (see Figure #2 below for recommended oil level).

Frank Driver says: Thanks for your prompt reply, a number of things have changed my mind about repairing the current installed trans-axle one of them being NO DRAIN HOLES!
Is there anyway that you can x reference the TuffTorq part number and the JD part number to find an axle that has drain holes and preferably an Eternal Expansion Tank for a higher capacity of fluid, if you could check this out for me I would be so grateful.
Cheers, Frank.

Hello,
I am sorry but that is not possible. The reason is simply that the transaxles we make are built specifically for the tractors that they are installed in. There would not be another unit that would have the same configuration internally that you have in the K46 that will just drop in.
Frank Driver says: Hi Graham,
My mower is a JD- L130 with KOHLER and 48inch deck bought new circa 2003 JDPP P/N AM131580 TuffTorq 7A646024390 S/N 46AC0147458
My questions are- What is the full K46 model number, is there a repair kit available and what was the original fluid/oil?
Many Thanks for your time
Cheers, Frank.
-
Hello,
The model number is K46AC and the part number for a new transaxle is 7A646024390 and the repair kit part number is 1A646099591. Original fluid is a conventional 10W-30.
I have AM131580 S/N 46ACO167689 tough torque transmission, can i use 5w50 full synthetic or should i use J20C. My L120 JD stopped pulling so i checked linkage and belt and found all ok so i removed unit and took cover off and the filter was clogged. I inspected all internal parts for wear but didnt seeanything but very fine scratches. Your help is appreciated.
-
Hello,
Yes, you can use either oil. We do sell our tuff tech oil here>> https://tufftorq.ordertree.com/tuff-tech-oil-3-liter-bottle.html
Henry Strydom says: I have a 2006 john deere 115 automatic lawn tractor that has done 1000 hrs. The hydro drive is a k46 iag460-24163. The PN AM134582 the SN 40J-0067947 also has this number on the bar code TUFF TORQ 768T2024010, I have drained the transmission completely and want to refill it with new oil.
I cant get tuff tech oil, but I can get TURF GARD will that be ok to use or should i be looking at 5w50 considering the hours.
-
Hello,
YOu can also use the John Deere Oil J20C. I do not have any data on the Turf Gard, so I cannot say if it would work.-
Thanks for your help. My problem is its only available in 20 liters at the moment they call it HY GARD (j20c) and from the jd website it looks like its for big tractors and equipment not that that is anything to go by. Is there no other alternative?
-
Hello,
Try using this John Deere part number> ty6354

My Husqvarna ride on mower has a Tuff Torque 426121 has limited and intermittent forward power (slows down to almost stop and then starts to move forward again and then speedup) but appears to work well in reverse. The machine has done 900 hrs so it getting pretty old. I have not checked the oil nor never serviced the transmission. Any suggestions on what might be the cause?
-
Hello,
I would start by changing the oil. Then you can check the linkages to make sure there is nothing bent broken and the pivot pints are tight.
Robert Crea says: John Deere LA110 won’t go forward or reverse however if I put tractor rear end on jacks wheels turn but with no power. Could it just be low on Hydrostatic Fluid?
-
Hello,
Yes, start with that. Also, check the linkages looking for any pivot points with too much slop making the control lever not traveling its full arc.
I have Countax fitted with gearbox p/n 7A646084280, the fwd/reverse input lever moves freely back and forth with no drive from the gearbox, could you indicate what the likely failure is? The tractor had started to struggle to go uphill and had been moving slower and slower.
-
Hello,
If the control lever does not cause the transaxle to move then inspect the input shaft and the pulley on top of the transaxle and make sure the splines are intact and the pulley is actually turning the input shaft. If it is then you will need to check the hubs to see if one of the keys is broken.
Joshua says: Craftsman T210 with the k46dm. Had 0 issues on my last cut. This time on the 2nd pass, mower was going slower and slower till it wouldn’t move at all. Checked belt and and linkage. Checked fluid level by removing batter and removing cap. Fluid level was fine however magnet was heavily coated. If I press petal as hard as I can it will barely move and some grinding noise is present. Should I replace the transmission or would I be fine with the rebuild kit?
-
Hello,
The grinding noise makes me wonder about the input shaft and the pulley. I would check those first.
Dennis Kik says: I have a 2008 John Deere X300 with a K46 Transaxle. Want to change oil to determine if that will impact issue with “power loss” going up hills. The only number I see is stamped – 5473964. What type oil and how much will I need?
-
Hello,
You would need to purchase the John Deere oil J20C from your local John Deere dealer.-
Thanks! Now I have a question as to how to find out which Transmission I have. The barcode is gone but do have the Serial Number of the X300. Anyway to find out which model of transmission I have from the model number, year and serial number? And from whom do I get it?
-
Hello,
Take the serial number of the tractor to a John Deere Dealer they can tell you the John Deere part number for the transaxle at the very least. I can cross that number so we will have an idea of what you have.

Dallas says: What kind and How much oil does a 7a646084091 hold?
-
Hello,
That has a conventional 10W-30 installed from the factory and so if you are topping off the oil that is what you would use. Otherwise, we recommend you use our Tuff Tech oil which can be purchased here>> https://tufftorq.ordertree.com/tuff-tech-oil-3-liter-bottle.html
It holds 2.4 Quarts
Help please!!..I bought a tractor with k46….runs great for 15 min then won’t move!…replaced oil with no better results…any advise?

Steve Pawlus says: What type of oil is recommended for my hydrostatic drive L130 mower 7A646024390 S/N
-
Hello,
With that unit you can use 10W-30 motor oil which is what is installed originally. or you can get the John Deere oil J20C.
Bert Bickelmann says: Good day,
I own a lawn tractor with a TuffTorq drive No. K460 S / N 001483 GP Jaromer P / N 358698.
I would like to add hydraulic oil to the oil expansion tank. Which oil can I use that is also available in stores (location Europe, Germany)?
Regards Bert
-
Hello,
That unit has 10W-30 installed so you should be able to get that easily.
-
-
Hello,
That is a K61C and the oil you would use is 10W-30 for that unit.
-
-
Hello,
What tractor is it? Also, is that serial number stamped in by the oil fill?
John Winnard says: I have a tuff torque 7A646084591, SN 46DMO746112 trans on my Craftsman model 247.27042. When going up a hill you can hear a slight whining . It has 113 hours. I’m wondering if I need to change oil ? It does not seem to slow down going up the hill but the whine is there. Any recommendations ? I bought the mower Sept 2018
Thank you
-
Hello,
Changing the oil is a great first step in finding the issue with your tractor. In doing that you will need to remove the transmission from the tractor so you can check for debris keeping the control lever from moving and also inspect the belt and pulley for damage. Also, check the linkages for anything bent or broken as well. Pay particular attention to any pivot points because as they start to wear they will eat up some of the movement of the control lever and it will make it so internally that the unit will not have as much oil pressure to move it up inclines.
mike Honeychuck says: can you remove case bottom with trans still in mower, will anything fall out? doing to do drain plug kit, i can access fill plug without fan removal.
-
Hello,
Stuff will fall out! You really need to remove the transmission from the tractor to work on it.
Olá o meu trinco a parte de baixo da caixa 46AW0170771, preciso do óleo e a quantidade, porém as autorizadas aqui em Valinhos SP BRASIL ninguém sabe o correto
-
Hello,
The volume is 2.3 liters and you can use 10W-30 motor oil. If you are just topping off use conventional oil. However, if you are going to replace the oil you can use a synthetic.O volume é de 2,3 litros e você pode usar óleo de motor 10W-30. Se estiver apenas completando, use óleo convencional. No entanto, se você for substituir o óleo, pode usar um sintético.
mark brice says: I will be replacing the oil in a Craftsman lawn tractor with the K436BT transaxle. Sears part number is 7A646084180. what is the weight oil and capacity? Can OEM oil be purchased from a local vendor? we live in eastern Iowa. Thanks
-
Hello,
If changing the oil we recommend using our tuff tech oil and it is possible you can find it at a local dealer. the part number is 187Q0899000 and it comes in a 3-liter bottle and the K46BT holds 2.3 liters so it is more than enough to fill your unit.
Brian Howard says: I have a 51A and wondering what the oil level in the tranny is supposed to be I’ve done a full rebuild of gears, shaft,pulley and resealed the case with new oil filter and fresh by5W 50 oil ..what is the level supposed to be in the small port / fill area? Large fill area doesn’t have the magnet on a key 51A does it? Just a large spring that holds the filter and media between the gear case and the pump and motor area
-
Hello,
You use the large fill port and please remove the bottom screen. Otherwise, the unit could airlock and not allow the full complement of oil to get in the transmission. There is not a magnet under the seal cap on the K51.
I have a Tuff Torq K46 axel no 5473964 . When we try to mow the grass it seems to slow down and then just quite. I have had this mower since 2016 with 1859 hours on . I was wonder what the problem is ? I talked to a mach and he told it is the pump is going out . He told me to drain the oil and put in new AMS oil 100%synthetic trans fluid Sae 20W -50 .I’m going to change it now and see how it works the mach said I may get one more year out it . Was wondering how much a pump for mower would cost .
-
Hello,
I do not recognize that part number for a transmission of ours. Is there another number on it that you can share?
Mark Moravek says: How do you purge the air?
-
Air Purging Procedure for Hydrostatic Transmissions
Check oil level.
Place vehicle’s drive axle on jack stands with wheels off floor.
Start engine and operate at low idle speed.
Depress and hold the forward pedal and open and close the bypass (tow) valve a few times. Next do the same for reverse. This only takes a couple of seconds to do. Note the bypass is typically the rod that is located on the back of the tractor that you can pull out to free-wheel the unit. Also note that this may take a partner or some assistance.
Depress the forward and reverse pedal(s) in a back and forth type motion with the bypass valve in the run position.
Repeat steps 4 and 5 until the axles start to move. This should only take a couple of times.
When the axle starts to move, increase the engine speed.
Repeat depressing the forward and reverse pedal until transaxle gives full response.
Turn the engine off. Remove jack stands while placing vehicle’s wheels on floor.
Thomas says: Hi I have a Husqvarna with a k46 transaxle. I loos power on the uphill after mowing for about 30min. Any suggestions?
How much oil should I put in. And what type will be the best.?
-
Hello,
It depends on which K46 you have. There is a bar code sticker on the case of the transmission that you can normally see from the rear of the tractor and on it is a serial number that will tell us which one you have exactly.
Rick Kloss says: I have Tuff Torq K46BR /7A646084220/ SN 46BRO347139, which is included on my John Deere X300 riding mower. I’m experiencing huge losses in power after mowing hills; seems to be a common problem. I intend to replace the hydrostatic fluid. Please advise on recommended replacement fluid and volume for my unit. Thanks.
-
Hello,
For that unit, I would advise the John Deere Oil J20C. The K46BR holds 2.4 quarts.
daniel Wood says: i have a viking t6 which has great power going forward but struggles in reverse. Any ideas
-
Hello,
I would check to see if there is any debris that is keeping the linkage or the control lever from moving as it should. Also, check any pivot points in the linkage as if there is a bit of slop in the pivots that can eat up movement for the control lever. you can also check the control lever for an added shock absorber as they can sometimes go bad and not allow the control lever to move as it should as well. if all is well with the linkage and lever you may need to try an oil change to see if reverse is showing the age of the oil first. Oil viscosity can cause a low power in either direction or in both directions.
Owain says: Hi, based in UK. have a 2002 Westwood t1800 with the K46 hydrostatic gearbox. all going well and absolutely no issues, until last mow when i noticed as i parked her back in the garage a patch of oil on the floor related to the rear axle. no power issues. up on jacks and the undersurface of the box is wet with oil, no obvious leak point. reservoir fitted under the seat is at a jaunty angle for some reason and is also wet with oil. was cutting across a lot of inclines and wonder if the oil has leaked from the reservoir due to severity of incline and poorly fitted cap; seem likely?
on a flat surface its tipped to the left by 30 degrees.
2nd question, what should the level be in the reservoir? full to brim? or room for expansion? tank is at a jaunty angle and not level as i said so somewhat difficult to tell residual volume.
3rd question, can i just top it up?
thanks for any advice!
-
Hello,
Yes, it could very well be that it was tipped and some leaked out and it could be that as it heated up because it was being used a little hard the oil expanded a bit more than usual and some then leaked out. The level in the reservoir as well as the top of procedure would require the serial number of the transmission so that I know which transmission you have so that I can be sure I am giving you the correct information.-
great, thanks. where will i find the serial number for the transmission? nil obvious!
-
It is on the case of the transmission close to one of the axles and normally you can see it from the rear of the tractor.

ralph parise says: My mower has 480 hrs on it and it feels like it might be slipping more than ever going up hill. Oil has never been changed, do you think that might be the problem? I did change the drive belt and it still slips. The transaxle gets warm also
Krish Kumar says: Hi,
I am from UK. I have Year 2002 made Countax C600H. The gear box/ transaxle is Tuff Torq K46E. S/N 46E-0020057. The drive is struggling on an incline after it gets hot.
Is there a service manual for this transaxle. What hydrostatic oil do i need to use for a change of oil.
Any suggestions would be deeply appreciated.
-
Hello,
For oil, the best you can get is our tuff tech oil with a part number of 187Q0899000 and it comes in a 3-liter bottle. You can order from our UK distributor Uni-Power. We do not have a manual for this unit but Unipower can get you PDFs of how to check and change the oil.Uni-Power

Ken Moore says: K46BA craftsman 21 up transmission whining mower stopped middle of cut
Drive belt on looks good All connections ok Plan to remove transmission
I would appreciate direction & comment Right repair kit and price on new or rebuilt transmission
-
Hello,
the K46BA is serial number specific to the repair kit. I would need the serial number of the transmission to point you to the correct parts. You can find the serial number on the case of the transmission close to one of the axles. Normally you can see it from the rear of the tractor.
William Strouth says: Hey I was wondering what kind of fluid does the hydrostatic k46 take.
-
Hello,
The installed fluid depends on which K46 you have because not all of them have the same oil.
Andy Cannizzaro says: I have a fleet of 3 mowers, all with Tuuf Torq 7A64 transmissions (MTD PN 618-07208. All run hot after extended use, but one developed this: It starts out fine, but over time it begins losing torque. It’s not as noticeable on a flat, but soon climbing a slope becomes labored and eventually it won’t make the climb. After a cooling off period, it starts out fine again. No sign of belt slippage – it remains cool to the touch. What could be the cause?
-
Hello,
I think you would want to change the oil in the transmission. Here is a link to the oil change procedure for that transmission. https://tufftorq.ordertree.com/media/promo/TuffTorq/cc%20K46%20K57%20T40%20MODELS%20WITH%20INTERNAL%20RESERVOIR%20CHECKING%20&%20%20ADDING%20OIL.pdf

Hello,
If you follow this link you can find the axle shaft kit for that unit (#202 on the parts list) and it is everything you would need to change both axles. It comes with both axles, 2 axle seals, sealing cap, filter, gasket material, and a 3-liter bottle of our Tuff Tech oil. https://tufftorq.ordertree.com/catalog/partslist/view/group_id/426814/?assembly=Parts&assembly_id=1593
CLIFFORD HOCH says: Can you give me a price of the fan (426120) at the top of the K46TB transaxle. Our mower wiring harness fell into the fan and broke 2 fins off.
-
Hello,
Here is the link to that transmission on the website.
https://tufftorq.ordertree.com/catalog/partslist/view/group_id/426786/?assembly=Parts&assembly_id=1557
Ken T. says: What was the reason why a simple drain plug was never installed on your transmission? Thus allowing for a much easier way to preform a fluid change!
-
Hello,
Drain plugs would be specified by the OEM to be installed. All our transmissions are built to the specs of the OEM.-
So it’s my understanding there is a 8mm drain plug kit that can be bought from TT I have a K46 model. And can plugs be installed without removing trans from tractor? Please provide links and instructions also!
-
Hello,
Adding drain bolts would be introducing a new way for the unit to leak and you are not saving any time since you still need to remove the transmission to fill it with oil. So, all in all, you are not saving time by adding drain bolts.

Richard Hayes says: What is the difference between a K46 and a K46BE?
-
Hello,
K46 is a transmission line that Tuff Torq produces and K46BE is a specific version of the K46 line. There are no generic K46’s. All are specifically produced for a particular tractor that they are installed in.
Eric says: Tuff torq 7A646084181
What are fluid specs, type and capacity?
-
Hello,
The K46BT originally has 10W-30 conventional motor oil installed. so you can use that oil but what we recommend is the Tuff Tech oil that comes in a 3-liter bottle which with a capacity of 2.3 liters it is more than enough to fill it. It has a part number of 187Q0899000 and can be purchased here>> https://tufftorq.ordertree.com/

Granville says: Can put tell me the oil level and and weight for a 7A646084321 the pic isn’t very helpful
-
Hello,
The K46CR (7A646084321) has conventional 10W-30 motor oil installed from the factory, so you can use that oil but we do recommend our Tuff Tech oil that has a part number 187Q0899000 and comes n a 3-liter bottle. You can order here>> https://tufftorq.ordertree.com/. The oil level is about halfway up the magnet under the sealing cap or an inch down from the case where the sealing cap sits.

Gary Cross says: What oil does Tufftorq put in replacement units?
-
Hello,
The oil in replacement units is the OEM-specified oil that is in the original transmission.
Brian Kundert says: I have a E170, bought new May 2020. It can barely climb any slight hill. Tried to pull my dethatcher (40″) and it could barely pull that. Since new it’s a gutless mower, can barely pull it’s own weight around. Was hoping it needed to get broke in, but after 20 hours its still a turd. Is there something I can adjust or should check?
-
Hello,
Those symptoms do sound strange for a new unit. It is still in warranty so I would contact a local John Deere Dealer for warranty information as the warranty goes through them. Also, what acreage are you mowing and how often?
Danny says: JD La130 looses power uphill,but goes fine backwards uphill.
-
Hello,
I would start troubleshooting this by checking the external things on transmission and making sure there is no debris on the case that could be stopping the control lever from moving its full arc. Also, check the linkages and especially any pivot points that could be loose and thereby robbing movement of the control lever. you can also try changing the oil to see if it will help the power issues.
Michael Thees says: I have a Husqavana LT 2654 when it gets hot I lose power climbing hills and comes to a stop, I have had it to 3 dealers . The first one said new transmission,(so we did) ,2nd said that the drive belt is glazed,(so replaced it) . Now the 3rd replaced belt filled transmission oil , still having the same issue ,he now says it could be a oil sending unit ! Please help before I put it out of it’s missery
-
Hello,
Let me understand you correctly, you replaced the transmission and the tractor is still not climbing hills? If that is the case then I would check all the linkages to the control lever. Especially the pivot points to see if there is some major slack in them that could be using up the movement of the control lever so it is not moving its full arc which in turn will mean that not as much oil will be pumping and thus a weak tractor.
Bruce Arrington says: Oil
Spect k46c-0077661
-
Hello,
Since it is a John Deere tractor you can use 10W-30 motor oil, especially if you are going to top off the oil that is already in there. Or you can get the John Deere oil J20C from a local John Deere dealer.
ES says: Hello,
I have husqvarna yth 1848 xp riding mower.
Does it have the k46 transmission?
If so is the 5w-50 is the right transmission oil for it?
-
Hello,
So that I can get you the best up-to-date information I would need the serial number off of the transmission itself. This will let me know the volume, the preferred oil spec, and the procedure needed for an oil change. If you could email that to me at customerservice@tufftorq.com I will get you the information you desire.

Je commencerais par changer l’huile de la transmission qui vous dira s’il s’agit de l’huile ou s’il y a de l’usure dans le circuit hydraulique. la meilleure huile que vous pouvez utiliser est celle de Tuff Tech que vous pouvez vous procurer chez le distributeur en France, Crosnier.Crosnier Sa

Hello,
I believe so, normally we tell people to use grease or some petroleum jelly to hold the small parts.
David Geuther says: Can I add a external tank to my K46 John Deere 300 , at this point it doesn’t have any, just bought this and it whines when backing up, also can I add the oil change plugs and what oil can I use to get greater longevity?

Hello,
For a John Deere tractor use the Hy-Guard J20C which is the John Deere high viscosity Hydraulic oil.

Daniel says: Why would tuff torq make a transaxle that must be taken out to change oil
-
Hello,
The transmissions are made to OEM specifications for the particular tractor that the unit is installed in. You can follow this link for tips and help in changing your oil. https://tufftorq.ordertree.com/oil-information
Chris says: Hello.
I have Husqvarna LGT2654 and is about 8 years old. When is hot outside and mower get hot I lost power and completely stop.
Read a lot what is going on.
Most likely transmission. What do you recommend in this. Remove it and change oil, buy a kit nad fix it or change it completely for new transmission.
It is K46 do you have upgrade for this kind of model or stick it with K46?
Thank you.
-
Hello,
I believe the first step is to change the oil and see if it gets better. Then if it does not you may want to think about a rebuild or replace.
Jack says: Hello, I am trying to rebuild my K46 unit but having trouble finding the kit specific to the model number… maybe you can help model # 7A646804180

Martyn Evans says: The speed on my K46 is great in reverse but in forward it is much slower. Any thoughts? It has been slowing for some time and gets worse as the machine warms up. New drive belt has not solved the issue.
Darryl Searle says: Hi I have a john deer L100 can you recommend a kit for fitting a drain and fill plugs
-
Hello,
we do not recommend adding drain bolts to a transmission that does not have them because it introduces a new leak point and it does not save any time because you still have to take out the transmission from the tractor to get the oil back in it.

stephen jones says: hi. i have stripped my 46k transmission because i found the seal on the resivor was missing..it had a large amount of dirt and grass in it. because of this i stripped the unit down to give it a complete clean..all went well until i started the motor and tasted the transmission..found the direction pedals were reversed.
how do i correct this problem,i thought i had followed all the information,and no parts over..any assistance to remedy this fault would be appreciated.
cheers stephen
-
Hello,
On the motor side of the hydraulic circuit, there is a wedge-shaped part called the motor housing and it holds the bearing for the motor cylinder block. That wedge-shaped part is the key to your issue because you have installed it upside down. If you flip the motor housing around the motor shaft 180° then the direction will be corrected.
LARRY THREATT says: have a John Deere 960r tran. leaks from the top I think around fan is there a rubber seal there can it b replace
-
Hello,
Yes, you can change the input shaft seal though I would start with a few other places to look before that spot. It may be necessary to pull the transmission so you can clean it up and see where the oil is leaking from. Places to check are the sealing cap that covers a magnet, the control lever area, the bypass lever area, and the brake lever area. Also, check the connections to the oil reservoir.
Bob F says: I have a 2010 John Deere X300. Tuff Torq 7A646084220, S/N46BR0291902, PN MIA 10959.

Yes you can use that weight of oil but the best version is the Tuff Tech oil that you can purchase here>> https://tufftorq.ordertree.com/catalogsearch/result/?q=+187q0899000
Dan Tandy says: We are in southern BC and do not get as cold as farther north does. The noise happens all the time, summer and winter. I let it run with the brake off for a couple of minutes to warm up the oil, it still does it but not quite as bad as when I first start it up. I also have a snowblower that I use on it with Chains and wheel weights on the rear tires with a counterweight on the rear. So I do use it in cold weather but the noise is not any worse once it warms up.
-
Hello,
Then if it is whining and it is not seasonally related then I would think about changing the oil. Whining can be indicative of broken-down oil viscosity and new oil should fix that issue.
Dan Tandy says: I have a Husqvarna yt42xls with the k46 transmision. 5 years old with 256 hrs on it. Cold the transmision whines badly, gets less noisy as it warms up but is still loud. Pulls ok all the time either cold or hot. Should I be concerned with the noise? Thank you Dan
-
Hello,
It sounds like the oil is a little thick when cold. I see you are in Canada, does this happen during the summer months or only in the colder months?
Walt says: There is a clunking noise in forward drive in my John Deere D-160 but not in reverse drive. It has just 88 hours total time.
Any guess as to the problem?

Hello,
I would check the linkage and the control lever for debris that could keep the control lever from moving its whole arc. Then check the keys in the axles and hubs.

Tim Davis says: When servicing by transmissions 7A646084460 on my riding lawnmower I am at the point of removing the black cap to drain and refill. I am having quite a time prying that cap off the transmissions. Any recommendations?

Tim Davis says: I have an 8 year old Cub Cadet LTX1046WK with a TUFF TORQ 7A646084460, S/N 46CA0013939. The reverse is very slow and now the transmission is noisy and slipping. Is all that is required a fluid change. Also, not sure what is meant by an air purge when doing a fluid change?
-
Hello,
I would definitely start with an oil change. that way you can check all the external things that can make your transmission not work properly. like the linkages and the control lever, making sure they are not bet or broken and also make sure there is not any debris that would hinder the control lever moving its whole arc. Here is a link to the procedure for changing the oil>> https://tufftorq.ordertree.com/media/promo/TuffTorq/cc%20K46%20with%20Internal%20Reservoir.pdf
Here is the air purge procedure>>
AIR PURGING PROCEDURE FOR HYDROSTATIC TRANSMISSION
1. Check oil level.
2. Place vehicle’s drive axle on jack stands with wheels off floor.
3. Start engine and operate at low idle speed.
4. Repeat opening and closing bypass (tow) valve while alternately depressing
forward and reverse pedal(s).
5. When vehicle starts to move, increase engine speed.
6. Repeat quick starts and panic stops until transaxle give full response.
7. Remove jack stands while placing vehicle’s wheels on floor.
Robert Lemings says: Hello, I have a Husqvarna YTH2348 with a K46xx transmission with over 700 hours. Mowing fine today, uphill and level. Had a few hard jerks, then stopped moving altogether, both forward and reverse. any thoughts?
-
Yes, you need to inspect the transmission and see if the belt is still on the pulley. Also, look at the bracing for the transmission and make sure it has not come loose. Next, check the linkages and the levers to make sure there is nothing broken. then it is checking the hubs and the keys that sit in the slots of the axles to make sure they have not broken. After all the external things are checked you may have to remove the transmission from the tractor and open it up to see if there is an issue internally.
-
After several hours of studying your procedures I have reached the following conclusion: If I remove the transaxle, repair it and refill it, I have to install it in the tractor to do the air purge procedure, THEN remove the tranaxle again to top off the oil, then reinstall it. Is that correct?
-
Hello.
It does say that yes. However, if you put the oil level about halfway up the magnet under the sealing cap that is a good level and you would not need to check it after purging.
-
-
Belt is on, pulley and fan are turning, axle keys are in place, wheels turn freely one forward the other backward as they should, linkages are intact. Suspect a broken output gear. Transmission is whining much more than it ever did. When this happened, the disengage lever at the rear had worked itself out about halfway which makes me think that a poorly engaged gear broke. Are there internal parts available for these?
-
Yes, there are which K46 do you have?
-
I’m about to give up and refill it – not finding anything mechanical, although I can’t see the input shaft bottom end, the bypass valve, or look inside the motor. With the unit on it’s back, I can turn the input shaft and the cylinder does not rotate – don’t know if it should or not. I’m afraid to completely disassemble because I can’t find parts for it – the only part I see on your web page is a new transaxle. Although nothing mechanical is evident, I find it difficult to believe that oil would suddenly go bad in the space of one minute – in other words, it was working and then it wasn’t in less than a minute.
-
Hello,
Here is the link to the transmission on the website. you have to order the repair kit (#201) to get all the hydraulic parts. -
Darn – have to destroy the input shaft seal in order to remove the shaft.
-
Ok, found the clip UNDER the splined nut. Apparently, the nut and clip are there to support the pulley – shaft will not pull out with the nut and clip removed. I’m missing something – is the shaft attached internally?
-
Hello,
The shaft only comes out after you remove the snap ring under the seal. -
Gears are all intact. Oil level was in spec and clear. I wanted to remove the input shaft and inspect that, but the repair procedure says to remove a clip but mine has a nut, no sign of a clip. Nut turns with the shaft. How to remove it and is it possible for it to be damaged on the lower end? What locally available oil (ie: motor oil) is suitable for refilling?
-
7A646084181, SN 46BT0516111.
The only sign I see of leakage is around the vent cap. -
If you have oil leaking around the vent valve then the oil is getting so hot it is expanding out the valve. you could be low on oil and the oil viscosity is more than likely shot. I would advise an oil change and if you follow this link it will show you how to do it. https://tufftorq.ordertree.com/media/promo/TuffTorq/cc%20K46%20AW,%20BA,%20BN%20&%20BT%20MODELS%20IN%20HUSQUVARNA%20CHECKING%20&%20ADDING%20OIL.pdf

Al says: Good day, I have a Husqvarna YT48XLS Model# 96043015500 with a K46 CR/LD transaxle. When it is cold, it will climb hills fine, but after it warms up, it will not climb anymore. Level ground is fine. I’ve never changed the transaxle fluid. Do I need a new transaxle or is there hope for just a fluid change? I have no leaks, and no other issues
-
Hello,
There is hope that an oil change will be the ticket. The viscosity of the oil can be shot and consequently, it will have trouble building pressure to do extra things like climb an incline when the oil is warm and thinned out. I would start with an oil change. Here is the link to the procedure for the oil change. https://tufftorq.ordertree.com/media/promo/TuffTorq/cc%20K46%20with%20Internal%20Reservoir.pdf

Ed Thoms says: I own a Husqvarna YTH2348 w/a K46 transmission. Last year I noticed that after it getting warm, it started sounding like a bad power steering pump and I figured I’d change the fluid, but to no avail. when it heats up (I am mowing a very hilly property) it loses it ability to climb. I was wondering if there’s a pump assembly or something to rebuild/replace? When it’s cold while it’s loud it works fine. after about 20 minutes it won’t climb. level ground it’s okay. any suggestions on what I can do?
-
Hello,
Can you get the serial number off the transmission? It is on a bar code sticker on the case of the transmission close to one of the axles. Normally, you can see it from the rear of the tractor. Get me that number and I can get you the repair kit part number which is a complete hydraulic rebuild.
Stephen Walsh says: Hi I have owned an LTR180 from new 2005 yesterday it stopped driving and it looks like the drive pulleys have collapsed. The machine is for home use and has not been worked hard, I have taken it my John Deere dealer for repair, I will ask them to change the oil, do I need to go any further than that, internal filter and so on?.
Thanks Steve
-
No, nothing else that should be sufficient.
Tim Cummins says: Hi just bought a 2020 jd e170 an I have read a bunch about the k46iht an was wondering how durable they are. Mine has the k46be iht any info would appreciated
-
The K46BE is a premium John Deere transmission with the John Deere oil J20C installed from the factory. That is the quality John Deere Hy-Guard high viscosity hydraulic oil. Do make sure you are not abusing the transmission with hauling heavy objects or towing heavy things with it. Keep the transmission cleaned off as this added debris can be a thermal blanket that does not allow the transmission to cool and the high heat will start to break down any oil faster.
kevin mcfarland says: I have an LTR180 Deere, k46a trans S/N 0037761complete loss of drive. at first struggled on hills not just get a slight movement going back or forward.
On inspection of disassembled trans some slight chipping on spider gears not a lot of metal on magnets. had a paper filter (new replacements I see are screens) Is it possibly just a dirty filter? all plungers in pump and motor seam tight no lateral play noticeable. since apart I was going to replace gears & new screen. pump and motor are fairly pricey if they look fine should I need to replace these assembly’s?
and if there is some wear to these assembly’s would a nice heavier synthetic be advised?
-
Hello,
I would inspect the other end of the cylinder blocks where they mate up with the center case and also the corresponding faces on the center case. you are looking for scratches or scoring. anything that oil can use as a channel to escape pressure. For filling K46A I would use 10W-30 or J20C the John Deere Hy-Guard high viscosity hydraulic oil.
Paul Gavin says: Diagram and instructions very helpful thank you Tuff Torq.

Hello,
I would start with the fluid change to see if it gets better. If it does then yes it was the oil.
werner reis says: when I use a lift to raise the front end of my riding mower [k46 transmission] oil drips onto the floor. I know it’s from the transmission. can this be some kind of failure of the vent valve and cap? I had to add a good quart of oil to the trannie when I lowered the machine and it did not move at all.
-
Hello,
It is not a failure of the vent valve. The oil will move through the vent which keeps the internal pressures low. However, you should check the oil level by removing the transmission from the tractor and checking the oil level at the sealing cap. Also, since the oil could have seeped out of the hydraulic circuit you should follow the purge procedure to make sure the air is out.
NIGEL TEALE says: After changing the oil with 5-40’s synthetic and cleaning the box my K46F runs a lot quicker in reverse than forward although I am convinced I replaced the tapered plate which fits onto the piston unit and alters the direction. Do I need to open up the box and refit the tapered plate.
Regards
Nigel
-
Hello,
So when you step on the forward pedal it goes forward or goes reverse?-
Hi Graham
When I step on the forward pedal it goes forward but slower than when I step on the reverse pedal which goes reverse but a lot quicker. I know for a fact that the tapered plate which alters direction was fitted correctly as I took photos when I initially started repairs and opened up the box. Any help appreciated
Regards
Nigel-
Hello,
So what parts did you replace? If you did not replace the center case (the part held in with 3 bolts) then it could be that the damage to the faces of the center case is showing up in forward first.-
Hi Graham thanks for your reply I did not replace the centre case held with 3 bolts I will strip down the box and check the condition
Regards
Nigel -
Yes, I suspect that there are some scratches or scoring on the faces of that part.

I am sorry but you would need to contact Hydro-Gear for those transmissions. They are a competitor of ours so I do not have any information on them.

Hello,
I do not have good tractor data so I would need the serial number of the transmission that is found on a bar code sticker close to one of the axles. Normally you can see it from the rear of the tractor. get the serial number and I can give you some suggestions.
Joel says: I have a cub cadet xt2. The turning radius is listed as 18″, but I have trouble try to turn at twice that radius. The back tires dont seems to have a differential gear and just push the front tires straight ahead. Is there something wrong with the transmission?
John Hargrove says: I have a YTH24V48 I just bought. I doubt if the fluid has ever been changed. It has 187 hours. I would like to put 5W50 in it. What can I expect to pay at the dealer to have this done? I believe this is a 2013. I have the model and serial number but can’t seem to find the info. Product # is 960450046. Serial is 012814A010040.

Jerome Weber says: Can I use aw32 hydraulic oil in my transaxle transmission instead of Tuff Torq k46 oil?
-
Gordon says:
Hi there, I have read your negative comments regarding the Tuff Torq transaxle and all the problems and repairs carried out. All I can advise is to try out some new Pullyes! Ypu’d mentioned an oil-change and also that the drivebelt had been replaced. If 100% properly purged (sounds simple but actually isn’t), well then if now power it can in my humble opinion still be a drivebelt issue. How to check this? After running it and noticing the slipping, stop the engine and get off, check directly by touching the drive pulley on the engine and over the drive axle. If these are warm or even hot, well then check by looking at the pulleys exactly where the belt runs. If all shiny well then the slipping is obvious and the heat confirms this. Then and although you’d previously invested in a new drivebelt you still have slip!

Hello, It holds 2.4 quarts.
NIGEL TEALE says: Hi Guys I have a K46f transmission but the pistons have started to stick. Have tried to order a replacement cylinder block 168T2025090 but the part appears to be unavailable in France. Can you advise me if it is possible to order a part or even the pistons and springs
-
I am sorry but you have to get the whole repair kit because the cylinder blocks are locked into that kit.
William Rial says: I sure learned a lot after reading the article. Many thanks.

Hello,
It should be anywhere from 2 liters to 2.3 liters.
James Howard says: I have a Westwood S1300 approx 2009 with a K46 transmission, after about 1 hour of mowing it loses drive going uphill, it is ok on the flat. Do I need to just change the oil, if so do Ii need to remove the transmission or can I draw the old oil from the reservoir tank.
-
Hello,
I would need to know which transmission it is. I do not have good tractor data, unfortunately, so on the transmission there should be a bar code sticker and the number I need follows S/N on that sticker. Get me that number and I can instruct you on how to change the oil.-
The number is s/n 46e-0037708

Bruce says: I have a leak in my JD L120 K46 transmission coming from the left rear bolt. I discovered a trail of oil up the drive and into the garage with a fairly large amount of oil in the garage. The apparent amount of spill would appear to be more than what is leaking from the bolt. I don’t see any evidence that the oil spilled down from the top of the trans yet it seems impossible that much oil could have come out through that slowly dripping bolt? The bolt was tight. What might cause this situation? What is the likely hood that the internals are damaged and a full rebuild is necessary?
-
Hello,
I would look for a crack in the case. Did you perhaps hit something? Unless you open up the transmission and inspect the hydraulic parts you will not know for sure about the damage. I would take the transmission out and inspect it really well for issues with the case. If nothing is found the you might want to get some RTV and re-seal the case to make sure it is not the issue in leaking.after filling it with oil and making sure it does not leak I would put it back in and try it.
Tim says: What are the thread/specs of the 114 fan bolt on the k46ca? Part# TT-1A646083090. Could it be replaced at a big box stores or is OEM necessary?
-
Hello,
Yes that is a specific bolt and I would not be able to say if you could find it any other place. Best to order it off the website to ensure you are getting the correctly speced bolt.
Keith Patrick says: Cub Cadet Model #13W1A4CA010. Loss of power up hills. Axle seal was bad, leaked all the trans fluid out. replaced the seal, used 15W-40 motorcycle oil to replenish, better power now, but still hesitates. am I better off rebuilding the trans or is there another trick I could try? If recommended to rebuild, where could I purchase the rebuild kit. This Transmission is K46 ETC. Also, the mower had ran for quit some time before the notice of any power loss. at one point, the mower stopped moving forcing me to troubleshoot and repair. Also, when i went in to fill the fluid, had to replace the fan as there were no blades on it (who knows how many hours of operation under this condition). Thinking the trans overheated, blew the axle seal, leaked out the fuid, (because i was stupid and didn’t notice) continued using all up until it totally stopped moving.
-
Hello,
I am sorry but I do not have good tractor data for Cub Cadet. I would need the serial number of the transmission that is found on a bar code sticker that is on the case of the transmission close to one of the axles. Normally you can see it from the rear of the tractor. get the serial number and i can give you a link to the transmission on the new website so you can purchase parts.
Rob says: I have Model # 40A-01250943 in a JD L108. Its starting to whine. Want to change the fluid. Is this the K46 trans, and what fluid (vicosity) does it take?
Thanks.
-
Hello,
that is a T40A transmission which is very similar to a K46. it is shipped with 10W-30 motor oil so you can use that or the John Deere oil J20C. -
Hello,
It is a T40A transmission. It is filled with 10W-30 motor oil and you can use that or the John Deere J20C.
Lee Roussel says: I have a Cub Cadet LT46 with k46 drive in it. I can cut for about an hour and after that it quits moving. Any info would be great on this. Just oil change or rebuild? I am leaning towards an oil change cause when it does pull it pull great with no issues. I have cleaned all debris from around it to make sure it’s breathing good. Fan on top is also good.
-
Hello,
Yes I recommend you start with changing the oil. your best oil is our Tuff Tech oil that you can get from our new website https://tufftorq.ordertree.com and the part number is 187Q0899000 and you need one 3 liter bottle as your transmission holds 2.3 liters.
Jim Barnes says: I have a John Deere L130 with 7A646024390 Hydro. It will not climb inclines anymore. Is rebuilding it ok or will I run into the same issues. What options are available ? This tractor still has strong motor and deck.
Thanks Jim
-
Hello,
Rebuild or replace are your options. Rebuild is not without some risk but it is not much of one. Or you can get a K66 replacement kit through RJR Tractors.
Adam Thomas says: Hi,
I have a 7A646024041 which has a small leak from the right shaft. Just wanted to confirm it is just the seal that is likely require repair (Seal 19*32*8) and if this can be replaced without breaking the unit down? Also it barely moves when under load after being used for a half hour. Replacement oil?
Thanks
-
hello,
Yes you can change the Axle seal without having to split the case though I do recommend draining the oil. At this link is a procedure>>

Thank you ggraham. Oil seal changed and oil replaced. No leaks but had to replace a shaft spacer as it was nye on welded to the shaft but got it off.
There is still a groan/whine when getting up to speed/under load, is this normal? It’s an old unit so won’t be perfect but almost sounds like it’s hurting! Noises don’t bother so if this is normal then I’m fine with it. Thanks again-
Hello,
Whining sounds are indicative of a hydraulic issue. It could be that there is some wear on the center case and the oil pressure that is bleeding off is causing the noise. However, every transmission does sound different which is something I learned on the production floor. If it has power I would continue to run it and see how it fairs.

Ed Mamon says: I want to remove the KK46BR-JOHN DEERE / 7A646084220 on my 2008 JD X300 to change the oil. It may be sluggish on hills but otherwise this is preventative maint. and the first maint for the K46. I have no leaks or other issues other than sluggish on hills. Is it worth me splitting the case for inspection and cleaning magnets or am I better just to get the TT3 in it and leave well enough alone? Hour meter is @ 261
-
Hello,
Just an oil change if all you have is a little loss of power on hills.
simon says: I recently topped up the transmission Oil on my WESTWOOD T1800 TUFF TORQUE K46 HYDROSTATIC Transmission.unit
I think I may have overdone the volume because since the top up I have oil leaking from the transmission on the garage floor which appears to be coming from the bottom of the transmission unit particularly after use . Should I be concerned I have caused any damage or. should I let I simply continue until it reaches a level where it not overfilled …thanks for your help
-
If you have over filled it then the oil will, as it heats up, expand out the vent valve and that is more than likely what you are noticing.

My test drive was ok for 10 mins but felt as though the IDS was jerky then all drive stopped both forward and reverse.

-
Hello,
Since it does not require the case to split we do not suggest changing the filter. Changing oil is another matter and you can find the lol change information at this link. https://tufftorq.ordertree.com/media/promo/TuffTorq/cc%20K51-K56%20MODELS%20CHECKING%20&%20ADDING%20OIL.pdf
I bought my tuff torq last year. It did good for the first year. this year It started cutting grass foreword and reverse no problem. then It quit,will not go in any direction. what is my problem? I probably put 12 hours on it last year.
-
Hello,
It is difficult to troubleshoot something remotely but you should start with all the external things first. Check all the pulleys especially the ones on the engine and the transmission. is there anything that would make them not work or bind thee belt or perhaps keys or splines that are stripped. If that is good then check the linkage. is it bound bent or broken? is the free-wheeling lever in the back left open. If all is well with those two items check the keys in the hubs. If one is broken the transmission will work but all power will be applied to the free spinning axle and the whole thing will not run. if everything external is good then it might be oil in which case you should remove the transmission from the tractor to see what the oil level is.
Keith Wilson says: My tuff torq stopped moving. When I removed the transmission and drained the oil it was milky. Would that cause the transmission to malfunction?
-
Hello,
If the oil was milky then water has gotten into the unit. it could be that the water is making the hydraulic circuit not build pressure as it should. to check this you can put in fresh oil and try the transmission.
Alan says: The thin metal pipe extending approx 2″ from the external reservoir down to my K46 is free to slide in and out of the transmission casing, and leaks. the larger diameter connection also leaks. Can you advise on the failure and the remedy for both these leaks, please.
-
Hello,
which transmission is in your tractor?-
William Cocoma says:
I have a craftsman t310 tractor that is almost a year old and I am having trouble with the hydro drive. It seemed ok when it was cold but once it ran for about 30 minutes it started slipping very bad. The tractor is still under warranty and I will have to call craftsman but thought I would see what you thought about the problem. I believe it is a k46 model. The transmission is dry on the outside so I dont see how it can be low on fluid either.
-
NIGEL TEALE says: Thanks GGraham
Nigel
-
No worries.
NIGEL TEALE says: Hi guys

Christophe says: Bonjour,
J’ai vidangé ma boite k46h par les 2 vis de purge situées dessous. J’ai refait le plein par le réservoir externe. La partie Gear est remplie mais la partie hydro ne se remplit pas.
Faut-il remplir par le capuchon noir ? Si oui, quel est le niveau recommandé pour une boite avec réservoir externe. Je pense qu’il faut remplir au maximum pour que l’huile coïncide avec la partie Gear.
Dans l’attente de votre aide. Merci d’avance.

NIGEL TEALE says: Hi guys
My honda 2417 hme mower (2006) is fitted with a Turf Torq unit 7A546024051 with external oil tank and s/n 46F 019174
My problem is grinding noise from the unit so could not find the drain plug but managed to get some of the old oil out and replaced with 30/50 multigrade engine oil as no hydrostatic oil available. The mower still grinds in forward and will not go uphill but not bad on flat ground, in reverse the mower grinds occasionally but climbs uphill no problem. Could you suggest a solution
Regards
Nigel Teale
-
Hello,
Grinding noise is indicative of the input shaft/ pulley starting to strip. Check that first but otherwise, it could be the keys on the axles or a gear issue and you would need to open it up to check that.
David Boothe says: Has anyone tried washing out the K46 with gasoline to get more of the old oil and metal residue out?
Is that a good idea or not?
-
Hello, I am not sure how gas and the seals would react. best to use cheap 10W-30 and flush out the transmission with that.
David Morieson says: Hello,
I have a k46; is there a torque setting for the bolts that hold the bottom sump on. My bolts were loosened with the intent to drop the sump but this was not required so the sump was not removed or the seal broken.
-
Hello,
The tightening spec for the center case bolts (M10) is 33~47 ft.lb. Case bolts (M8) are 16~18 ft.lb. I would tend to stay to the lower end of the spec as the case is an aluminum alloy and soft compared to the bolts.
ronnie says: is the magnet that goes under fill cap available by itself–I’m changing oil an mine is broken in pieces–k46 transaxle
-
Hello,
Yes, it is. use this part number 19216324360 on our new website tufftorq.ordertree.com and you will be able to order it.
Troy Lynds says: In a K46 rear end you are saying to refill with 5w50 synthetic, right? Could you at lucas oil stabilize as well? Also have automatic hydrostatic oil 56 would this be any better to help the rear end from heating up?
-
Hello,
I am sorry but I do not have any test data to provide an answer. So I am unable to tell you if it will work or not.
Steven Carey says: I have a k46. I had to cut out the fill cap to remove it . I see there is a steel cap. Would that replace the rubber one?
-
The new cap is steel with rubber over it. The part number is 187T0136300.
Clyde Snow says: I have a K46 in a D130 that is gets hot and slows down and blowing oil out the fill plug what can cause this
-
Hello,
That sounds like you are either overheating that transmission or there is damage to the hydraulic parts. Since that unit is a John Deere you would need to contact a local dealer for help. I am no longer able to offer assistance because John Deere wants to service their own transmissions.
Tom Craig says: I replaced the original k46 transmission in my x300 which wouldn’t move once it warmed up with a new replacement k46br from john deere. I now have 15 hours on the new transmission, how often should I change the oil in it so it doesn’t do the same as the first one? What is the best way to drain the oil out and where do I get new oil for it?
-
Hello,
For the transmission, you should refer to your manual. I am required to direct all inquiries to a local dealer or you can contact the John Deere Tech Center at 800.537.8233 or globalsupportcenter@johndeere.com.
C.L. says: Why does tuff torq recommend 5w50 over the original 10w30 for most applications? That is a significant viscosity change, I could understand switching from the original 10w30 conventional to synthetic 10w30. But why to 5w50? Thanks for your time.
-
Hello,
That is the oil that we test exclusively. It is a good catch-all for hot weather applications as well as cold weather applications.
Jeremy Wajer says: I have a K46 transmission (I believe) without reservoir that is in my John Deere L130 S/N GXL130A117878. I know it should take 2.4 its, but how high after purging air should i have the level? Up to where the magnet sets so once it heats up it runs past or all the way to the top with magnet installed? Thank you!
-
Hello,
About halfway up the magnet is a good level.
ron Ehman says: what is best way to purge a K46DM on a cub cadet?
-
Hello,
You need to put the tractor up on jack stands and with the engine at a low idle you engage the forward pedal and leave it on till you see the wheels start to move strongly and then do the same for reverse. If you have help, a second person can open and close the free-wheeling lever in the back of the tractor to get the air out a little faster.
Newton Foster says: Hi there, is it possible to reinstall the same cap after removing? I removed the upper plug and drained mine after I had a main drive gear failure. I’m about to install it and reassemble my mower, thanks in advance
-
Hello,
Yes, you can reuse the cap. If it was not damaged in removal.
Joshua Wilfong says: I have a husqvarna yth24v42ls and I recently noticed the k46cr to be leaking fluid. Is it possible that changing the fluid would resolve the issue? Thanks so much.
Have a great day.
-
Hello,
I would not think changing the oil will help unless the oil is coming from the vent valve. If that is the case then the oil must really be getting hot. the oil is probably spent then so you would want to remove the sealing cap and flip the transmission over to drain the oil and fill it through the same orifice. You would put the oil level about halfway up the magnet that is under the sealing cap and that is a good level.
Kurt snell says: I have a k46v how much oil it take to fill
-
Hello,
It holds around 2.4 quarts.
what is the total amount of hydrostatic oil do fill a tuff torq K46 transmission?
-
It all depends on which one you have and it if it has an external reservoir or an internal reservoir. External is around 2 quarts and internal is 2.4 quarts.
Robert Garrett says: If the Tuff-Torq 918-07009 rear end is completely empty how much fluid should it take to fill it ?
-
Hello,
The number in your post is not the Tuff Torq number it is the MTD number. It looks like that translates to a K46DS and it holds 2.4 quarts.-
Thank you so much
-
ive got a tuff torq 46c the only thing i see is a side screw port is this where i check the fluid level and also fill it also axle seal is leaking how do i get it out and install new one do i need to remove axle and split it thanks very much for any accurate advice
-
Hello,
That side screw is the cam that sets the neutral for the control lever spring. You check the oil level at the sealing cap under the fan and pully near the front of the transmission. There is a magnet under it and you should have oil about a third of the way up the magnet. On the website https://tufftorq.ordertree.com/ there is a “need help” tab and in there you can find the procedure for changing the axle seals.
J.L. Forge says: I have a 2016 Cub Cadet XT2 Enduro Series GX54 (26 hp Kohler/54″deck). It just started leaking oil from the left rear wheel seal area. I thought about replacing the seal and have been advised there is a cap on the top side under the seat/battery area to top off the oil. I have not checked this yet but if so, what would be the best oil (10w40?) to use to top off? Thanks a lot!
-
Hello,
you can use a 10W-30 or 5W-50 synthetic motor oil. Our Tuff Tech Oil is best and you can order it right off the website using the part number 187Q0899000.
Wayne Martin says: How much oil does this K46 require?
Mike says: I have d160 2011 does it have the k46 . I want to upgrade to the k66 can it be done and fit

Hello,
It can be done but you would need to contact RJR Tractors at (877) 333-8811 because they have developed a KIt to upgrade your K46 to a K66.
John says: I have a lhusqvarna 24 48 with a k 46 transmission worse good forwards and reverse but is freewheeling going down hills and can be pushed without pulling release wire will oil change help this

Hello,
You might want to open this up and inspect the internal parts. There could be wear on the hydraulic parts causing that problem.
Danny Levengood ii says: What fuild should be in a k46bt
-
Hello,
If you are going to just top off the fluid the oil is a 10W-40. If you are changing you should use 5W-50 synthetic oil.

I have a Simplicity Broadmore 44 with a K57 in it. Sticker says K57 only. No R, A etc. Will a K57R fit it?
-
Hello,
The transmissions are built specifically for the tractor that they are installed in. So swapping is fraught with issues the least of which is the height of the fan and pulley stack up. if it is a K57 than it is either a K57A or a K57K.
William Talley says: I have a John Deere L130 it has k46 rear end in it I’m fixing to change the oil how many quarts of oil does it take and what kind oil ?

Hello,
It holds 2.3 liters or 2.4 quarts.
Kathy says: I have a k46 AW what does the AW mean
-
Hello,
The AW designates which K46 the unit is. Think of it as the name of the transaxle.
Al greco says: How effective is syphoning out oil and just add new oil.?
-
Hello, it is not very effective since there are two chambers, hydro and gear. you need to make sure you can get into both. Your best bet is to just flip it over and drain the oil. That way you are ensured to have most of the oil out of the unit.
Jonesy says: Hi, My K46 is still jerking for about 5-10 minutes from cold, after which it is fine. If I pre-heat the gearbox to say 85F, it runs fine out of the garage.As the oil has been changed for a 5W-30 does this suggest that there is internal damage? Thank you.

scott tanner says:
Dear Sirs, I have a 2554 Husqvarna lawn tractor. I had a problem with it when it gets warmed up it doesn”t want to go up hills. I took the transaxle out and disassembled it. the only thing I seen any wear was the springs in the motor and pump. All pistons and cylinders looked very clean with almost play or wear on the chrome of the pistons. I replaced the springs with new ones, put it back together. and it goes forward in reverse. and backs up in forward. Can you tell me what I may have done to cause this? Should I have replaced the pump and motor?
Don Morgan says: Hi, Recently (for the 2nd time) the left rear axle on my Craftsman mower broke at the point it enters the transaxle housing. I mow about 1 acre on flat ground and am wondering if this is a weak point on the axle. This K46 is about 6 years old – the first one was about 3 years old when it broke. The first time the dealer sold me a new transaxle and what I have for numbers are K46BN 7A646084160 468N0046861 – The numbers are coming from my paperwork because the units do not have the sticker on them. I kept the original transaxle and am debating on attempting to just replace the broken axle or replacing the mower. If I opt to repair either or both units is that doable for someone with fairly good mechanical abilities or does it get technical? Also are there repair parts available?
Thank you for your time……..
Artur says: HI, I’m looking for a specification of the transmission my CastelGarden tuff torq PIN 18400965 s/n 7A646024410 46T 0644136.
I appreciate if U would help me in.
-
Hello,
Which specification are you looking for?
Jonesy says: My K46 has started hesitating/slipping and growling when cold, forward or reverse. Cold here is say 5 celcius. After about 10 minutes of use, I get full power no problem. In the summer it’s fine all the time. Belts , pulleys and linkages are good.
I topped up the oil last year and it seemed better, but it seems much worse this winter.
Any ideas?
Thank you
-
Hello,
I believe that it is the oil being too thick at startup since it is cold. you could try a 5W-50 synthetic oil and see if that helps.-
Thank you for the suggestion. I ran the mower last night, it was around 20 celcius. The K46 was hesitating/slipping for around 10 minutes until warm. I drained the oil last night and re-filled this morning with 5w-50 100% synthetic. It’s the same from cold, probably around 15 celcius hesitating/slipping a little, but after less than 5 minutes it was running fine. I’d say there is no change in the power available. The K46 has approx 120 hours, and this is the first oil change. I bought the mower at 80 hours.
I’m thinking that maybe this is normal behaviour and I’m over-sensitive to the growling/hesitation. I’m used to a gear-shift!
Thank you

Michael says: What is the difference between a k46c and a k46a? Thank you
-
Hello,
Those are both K46’s but the differences are significant. The “A” is configured with an external reservoir and IDS system and the “C” has an internal reservoir but no IDS.
mack says: HELLO!
I have a 2018 John Deere E140 with K46.
If I press the foreward pedal harder I go faster. If I press less I go slower.
Am I riding a clutch to go slower ? Will this damage the K46 ?
Should I always press the foreward pedal fully ?
-curious in Crescent City…

Hello,
How the transaxle works is that the control lever that is hooked to the pedal moves a part known as a swashplate. That swash plat squeezes pistons in a pump that force oil through an orifice which pressurizes the oil and that oil pressure is what drives the tractor. if you push down real far on the pedal then the swash plate really squeezes the pistons and you get more pressure and go faster. If you only press the pedal halfway, the swashplate will put less oil through the orifice and give you less pressure which will give you less speed. It is perfectly all right to run the pedal wherever you need the speed to be. For instance, in turning you might want to go slower around an obstacle. The transaxle is designed to do this and you are not hurting the it at all.
John Melcalf says: I am looking for T40J hydraulic pump maximum PSI. I could not find anywhere in either tufftorq nor kansaki web site. Do you know where to find it?
-
Hello,
What pressure are you looking for?
Michael says: Hi, will any k46 fit a John Deere Lt180
-
Hello,
According to the John Deere website that tractor had a K46C installed in it. That is the transmission you would need to purchase or get parts for.
Grant Simmons says: Sorry, one more thing. I assume the transaxle is a K46.
-
Hello,
Yes, it is a K46CR.
Grant Simmons says: I have a Tuff Torq transaxle and the following information is listed on its ID tag:
TUFF TORQ 7A646084321
S/N: 46CR0090284
HOP PN: 426121
I obtained it from an older gentleman who liked working on lawn and garden equipment. For health reasons, he reluctantly had to stop. He had this transaxle, but couldn’t remember what model or brand of equipment it fit. Very clean unit. Drained the oil (only 1/2 quart approximately) but it was pretty clean and contained no metallic particles. Magnet under fill plug had a slight grey film – appeared to be from normal wear and tear. If you could tell me what equipment it would fit and whether or not it appears to be ok based on the oil and magnetic observations, it would be much appreciated. Thank you.
-
Hello,
The K46CR is a Husqvarna transmission. I do not have great tractor information but I do know it was used in these tractors: YT42XLS, YT48XLS, YTH24V54XLS. Other than filling it with oil and trying it you will not know if it is working or not. To be really sure it is good you would need to open it up and inspecting the hydraulic parts. The oil you would want to use is 5W-50 synthetic motor oil. Our Tuff tech oil is best (187Q0899000) but to try to see if it will run any will do.-
Rik says:
FYI – my owners manual for Husqvarna YT46LS also identifies the transmission as TUFFTORQ K46CR(426121).
Could you possibly send me a pdf on changing the oil in this transmission? Curiously, does consistently mowing in both forward and reverse create any additional wear vs just mowing in forward? I have plenty of landscape obstacles to maneuver around so find myself backing more than I like.-
Hello,
The oil change procedure is here at this link>>>

Charles Everhart says: Will k46 hydrostatica axle work in a L LT155 deere
-
Hello,
I am sorry but a K51 is installed in the LT155 and a K46 does not have the same bolt in pattern nor does it have the same linkage hookups as a K51. So, without lots of modification to the tractor, it is not possible to substitute a K46 for a K51.
Jack clifford says: I re did the seals in my tuff torq k46s transmission. Now when I press the forward pedal it goes backwards and the reverse petal it goes forwards. Anyone come across this before?
-
Hello,
You have installed the wedge-shaped motor housing in wrong. It needs to be flipped 180 degrees and it will fix that issue.
Mike Vandam says: Hello, changing my fluid, can you tell me the capacity for my k46 please.
7a646084321. S/n 46cr0078626. Thank you!
-
Hello,
The K46CR holds 2.3 litres or 2.4 quarts. The best measure is to fill the transmission until the oil level stabilizes at 1/2 way up the magnet that sits under the sealing cap. That is a good level.
Mark lambert says: Hi I have a k46 bt what is the adjuster and lock nut on the right side for and how to set it. How much oil does it take.
-
Hello,
That nut is the cam that sets the neutral on the control lever spring. The transaxle holds 2.3 litres which are 2.4 quarts.
Nolan says: Hello. I have a k46bn on my husqvarna gth2654, i recently broke the left axle somehow and i am trying to figure out what axle repair kit i need for this transmission. Thank you

Bobby Ball says: Hi. I have a countax with a K46E .
On start up the mower will not move but if you give it a push and drive it for 50 yards it is then fine..
The mower is 15 years old and had moderate use
Can you help?
-
Hello,
It would be a good Idea to try to change the oil in the unit. That is a great first troubleshooting step to take. You can check all the externals and make sure they are working correctly. If it gets better than it was the oil if not then you know that the hydraulic parts are probably worn.
Shannon Heaverin says: Can I use 15w-50 in the transmission. I have 3 quarts of it already.
-
Hello,
Though it is easy to think other oil types will work in replacement of the recommended oil, our oil is actually a very special blend designed to be used in Tuff Torq transmissions. Even the 10W-30 we have is not normal motor oil. these are specially blended to be used in these transmissions. So though you can use whatever you would like the recommended oil, as I stated before, is designed to be in the transmission.
Justin says: Sorry one more question…. The sticker on my JD D160 K46 says 7A646084121. Can you tell me the oil capacity?
-
the K46BE holds 2.4 quarts, approximately.
Justin says: How can you “purge the air” with the transaxle on the bench? I’ve read the procedure to do it with the transaxle installed, but on a John Deere D160, I’d then have to pull it back out to top off the oil since there is no access to the top of the transaxle.
-
Hello,
Purging air on the bench does not get the build-up of RPMs to make the transaxle run strongly. Typically a drill will not get you the power you need to do this quickly. It is best to install the transmission back into the tractor and purge it up on jack stands. Filling the typical K46 with oil halfway up the magnet is a good level for the oil to be at pre-air purge.
Benjamin R says: Also transmission has to come out doesn’t it?
-
Yes, it does.
Benjamin R says: I have an lt 166 j.d. and have noticed a little oil on the back of the gas tank. I’m guessing it’s from the transmission and seems like it’s lost a Little pulling power. Do you have an idea on fluid capacity and fluid type? Any help would be appreciated
-
Thank you for your inquiry,
Capacity is approximately 2.4 quarts. I am including an image of where the oil level should be.
Glenn MacNeil says: We have a Cub Cadet ride on the mower will work for awhile then starts slowing down going up hill. Oil was never changed in it. Can it be low on oil or has the oil broken down so badly it has ruined the transmission? There is 220 hrs on the machine but we cut hilly terrain . Thanks Glenn.
Eddie Lambert says: Pulled transmission apart changed oil put back together/ now mower goes forward on reverse pedal and forward on reverse pedal, what hav we done wrong.
-
Hello,
You have installed the wedge-shaped motor housing upside down. Flip it around 180 degrees and it will fix the issue. So if the wide side is towards you put it down so that the thin side is towards you. Or vice versa.
Jack Mendelsohn says: I have been readng all of the Q & A and will be draining the trasmission and changing the oil and am considering adding Lucas transmission additve. I would appreciate your input on this.
-
Hello,
Tuff Torq has not done any testing on the additive you mentioned. Therefore, I cannot give advice on whether you could use it or the safety or efficacy of the additive. You can add it if you would like but I cannot give advice to do it.
AR Warren says: Husqvarna YTH24K48 I understand it uses a K46BT transaxle. When stepping on peddle for forward motion there is a long delay, tractor starts to move slowly until getting to normal speed. If stopped it restarts just as slowly. In reverse no dely at all. Engine runs fine, rpms remain constant. 144 hrs on tractor about 5 years old
Hello I have a K46A transaxle and I took it off the unit as it would run for 20 minutes and then stop moving. I let it rest for 20 minutes after the oil cooled down and then the unit would run for another 20 minutes. I just saw a video that showed how to drain the oil from it and noticed that there was hardly any oil in the unit, and whatever I was adding thru the air vent would come out after it heated up. Could it just be that I need to add oil to the unit and put it back together instead of rebuilding it? The unit does not whine or make noises when it moves but after 20 minutes it stops. Thanks for your advice!
-
Hello,
the best first step is changing the oil in the transmission. Getting fresh viscosity in the unit will help determine if it was just the oil or there are some other issues. Use a 5w-50 synthetic, our tuff Tech oil is best but you can try what you can find. Most K46’s hold 2.4 quarts. As always if you have other questions you can contact the Service Department at 866.572.3441 or email at salessrvc@tufftorq.com.
Bobby shepherd says: 1870 Christopher Trace Is the center section on a John Deere what makes in go in forward and reverse ?
-
Hello,
The control lever makes the transmission go forward and back with the swash plate squeezing the pistons of the pump cylinder block. The motor housing determines if the control lever going towards the front of the transmission makes the transmission go forward or backwards.
Justin says: Will 20w50 work in a k46
-
Hello,
I do not have any testing data on that weight of oil. We only test with the oil that is installed in the unit or our recommended oil. You can try using anything but officially I cannot say if it will work or not. Of course, as a recommendation, the superior oil to use would be our premium Tuff tech oil part number 187Q0899000 and it is $28.50 for a 3 liter bottle.
D. Konze says: Hi,
I have a K46BE in my JD L130. I changed the filter and oil using Tuff Tech recommended oil. The trans drive belt started to slip badly. I replaced the belt and much improvement. But, it still slips going up a grade, even with a helper spring on the tensioner. Do I need to go to a lighter weight oil? I read that JD uses 30 weight.
GARY MCINTYRE says: I HAVE A TUFF TORQ K46DM HAS RED FLUID LEAKING FROM BOTH AXELS. JUST WONDERING WHAT TYPE OF FLUID SHOULD BE IN THIS? This tractor is 2015 with 90 hours on it… not sure if I should change the seals or the fluid?
-
Hello,
There should not be “red” liquid leaking from the transmission. We install 10W-30 in the K46DM. Unless someone changed the fluid it should be a motor oil in the unit.
Rexford Parrish says: What about the second black cap that is not under the cooling fan assembly. Do I drain that as well and what type and how much fluid goes back in the unit?
-
Hello,
That is the vent valve and when you drain the oil it will also drain the chamber (gear chamber) under that cap. Filling at the sealing cap under fan and pulley stack up will also fill the gear chamber. So the same oil goes in both chambers.
Ken Smith says: Thank you, ggraham. I will save this information. My searches today suggest going stronger may be more important than just pursuing a locking option.
I found a reference to updating the K46 with K57 internals. Do you have any knowledge of this?
-
Hello,
It is unfortunate but we no longer offer that as a service. The Engineer who kept up with all the parts changes has retired and no one has taken up that mantle.
Ken Smith says: I forgot to add the K62 is available on this tractor as an option with the large deck. The linkage could possibly be sourced from Cub Cadet.
Thanks.
-
Hello,
I think that would be a question for Cub Cadet. Since we do not see the transmissions in the tractors it is hard to say what would work.
Ken Smith says: Greetings. My 2018 Cub Cadet XT2 came with a K46 transmission. Due to the terrain on my property I am compelled to use tire chains even in good weather. Is there a transmission (K 62 perhaps?) with a locker option that I can swap in easily?
-
Hello,
There is not an easy swap between transmissions due to the fact that these transmissions are built for the specific tractors that they are installed in. That being said there is a company in Washington, not affiliated with Tuff Torq that has a K66 upgrade. His contact information is below.

Luis says: Hello. My husqvarna k46 is not driving. I noticed that a rear tire has bluish oil all over it. I believe an axle seal is blown and lost oil from here. Do I need to open the transmission to replace this or does it seat itself from the outside? Also I read about using 5w50 syn. Oil. Does this seem correct.
Thank you
-
Hello,
You can change the seal from the outside without splitting the case. look at this link for more information:Axle seal replacement As to the oil we do recommend a 5W-50 synthetic oil if you are doing an oil change.
Montri Chaisakul says: I have a Craftsman Garden Tractor. It works fine for the last 10 seasons. It started to stop and transaxle winning before it climbed the hill but it cut grasses fine in flat area in 11st season. I removed the transaxle from the tractor today. This is the info from the transaxle:
TUFF TORQ 7A632084620 S/N: 66Y – 0002589
HOP PN: 199973
The reservoir has only small oil left in the tank. However, I have not drain the oil from the transaxle yet. There is no leak (as far as I can see from the housing. I would like to change and refill the transaxle fluid. What type of fluid it uses and how much? The reservoir has marks and show the level of fluid. However, there is no dip stick on the transaxle housing. How do I know that it is the right amount of fluid?
I will greatly appreciate any info that you can provide.
Best regards,
Tyrone Moore says: this Transaxle is loosing oil by spacer split how to stop it or how can i find a Transaxle
-
Hello,
Which transaxle is it that you have? If I know that I can help pinpoint parts or a replacement. There should be a barcode sticker containing the serial number of the transmission on the case close to one of the axles.

John Hawes says: I followed your instructions for oil change and bleeding air.
I have a Husqvarna YTH24V48LS
Refilled with 10W50 synthetic oil but now it loses all drive after approx an hours operation.
Any suggestions?
-
Hello,
It would seem that the oil is not able to make up the difference for the wear on the hydraulic parts. You would need a repair kit which is a complete hydraulic rebuild. You can contact the helpful techs in the Service Department at salessrvc@tufftorq.com or call at 866.572.3441.
I just received my new transmission and noticed it was full of oil. Do I have to drain the oil out and put new oil in or is it good to go?
-
Yes, it has oil so it is ready to drop into your tractor.
Jason Chlebowski says: My LTX1045 is leaking oil from the vent valve. I have added oil to the transmission several times and it continues to lead from the vent valve. I do have 125 hrs on it. How do I eliminate this problem?
-
Hello,
If oil is coming out of the vent valve then the transmission must be experiencing some rather rough treatment to make the oil heat up and expand that much that it is leaking from the vent valve. You might want to check to see if the fan is intact. Otherwise, I would change the oil and see if that helps.
Garnet Luick says: 2004 LTR180 with K46A external expansion tank. How do I check the trans oil level? Can I simply top up the oil in the expansion tank to keep the trans oil level at the correct level or or I have to add oil in the oil port under the fan?
rusver briceño says: hola tengo una husqvarna con k46 y el problema en esta es que después de 20 minutos de trabajo pierde toda la fuerza y ya cambie el aceite y el problema persiste 🙁 ¿que es lo que estara pasando?
-
Hello Mr Briceno,
It sounds like there could be wear on the internal hydraulic parts. The oil is using this to escape pressure especially after it warms up and thins out. After checking everything externally like the pulleys and the linkage your best option would be to rebuild the hydraulic system or replace the transmission. You can order parts right off of the website: https://tufftorq.ordertree.com/. And as always you can call the helpful service techs in the Service Department at 866.572.3441.Parece que podría haber desgaste en las piezas hidráulicas internas. El aceite lo usa para escapar de la presión, especialmente después de que se calienta y se adelgaza. Después de revisar todo externamente, como las poleas y el enlace, su mejor opción sería reconstruir el sistema hidráulico o reemplazar la transmisión. Puede solicitar piezas directamente desde el sitio web: https://tufftorq.ordertree.com/ . Y como siempre, puede llamar a los técnicos de servicio útiles en el Departamento de Servicio al 866.572.3441.

John A DuBan says: I have a 2007 Craftsman MTS 5500 tractor with a K46 transmission. The number on the axle appears to be 7A646084161 SN#468N806013. The transmission quit working while vaccuming leaves and going up a small grade. It has some power going on level ground but will not climb a hill. The case is clean as there are no signs of oil leaking. What should I be looking for?
-
Hello Mr DuBan,
It sounds like you need an oil change in your transmission to be sure of what you are dealing with. It can make the transmission run again but it is not a guarantee to fix the issue. But it is a great first step in finding the problem. When removing the transmission from the tractor you want to pay particular attention to the linkage, fan, and all the pulleys on the tractor. By checking these external issues you are making sure that they get eliminated from the list of possible issues. If all is well with the externals, change the oil and see if it helps. If it does, Great, then you had an issue with oil viscosity. If it does not get better or only slightly then you have wear on the internal hydraulic parts that the oil cannot make up for and a repair kit is what you need to replace the worn parts to get your transmission running like new again. You can always contact the service departments friendly service techs at 866.572.3441 or email at salessrvc@tufftorq.com.
Tyesen Robbins says: How much fluid does the K46 tranny hold?
-
Hello Mr Robbins,
Most K46s hold 2.4 Quarts, however, there are a few that only hold 2 Quarts. It depends on whether or not the K46 in question has an external reservoir or an internal one. The internal reservoir units hold more oil.the rule of thumb is that the sealing cap with the magnet underneath of it is the easiest thing to look at for oil level. Keep the oil level at 1/3 to 1/2 up the magnet and that will be a good level for the transmission. And as always, if you have more questions you can contact the helpful techs in the service department by phone or email at salessrvc@tufftorq.com or 866.572.3441.
-
Hello,
Adding drain bolts to K46s that do not have them can be a problem waiting to happen and in reality not save you much time at all. The problem is having to pull off the lower case off to drill and tap for the drain bolt holes and now you have introduced a new way for the transmission to leak oil. Time is not really saved due to the fact you would have to still have to remove the transmission from the tractor to put the oil in the unit. We try to talk owners out of doing it for those reasons. However, you can always contact the friendly techs in the Tuff Torq Service Department by Phone: 866.572.3441 and Email:salessrvc@tufftoq.com if you have any further questions or for more clarity.
Thanks for sharing the information. i really enjoyed your blog article. and you’r writing a good point.
Frank Sherman says: Hi Guys,
I have an L110 John Deere and had a leaking seal on the input shaft . I removed the trans-axle and brought it to my local dealer for replacement. After installing it there is no grunt in the machine. It cannot even climb a small hill. I removed it again and found the oil level a bit low so I topped it up with about a cup of suitable oil. Could this be the problem, ie. low oil? If I need to rebuild the pump assembly/motor can you supply a rebuild kit? I am in Australia and find the John Deere people here only want to sell a complete trans-axle.
arnold says: i like your page but dont go far enough some these tractors work all year round so the oil spec declare what type of oil

Hello Mr. Arnold,
What transmission do you have? Perhaps with that information, I can find out what would be best.
DANIEL MCCALLUM says: Good evening. I own a John Deere L130 lawn tractor. Manufactured date 05/12. It doesn’t move at all. Raised rear wheels off ground tires do turn slowly,but I can stop simply by touching wheel. I understand their maybe a problem with K46 trans. What is my best option for the money to repair or replace.
-
Hello Mr. McCallum,
You should check all the external things first. Making sure the control lever is being pushed and pulled through the whole arc that it can travel. Also, you should check the input shaft and the pulley making sure that the pulley is turning the input shaft. After that, you should check all the pulleys from the engine on to make sure you do not have a problem that way. If those things are all good then you might want to open the transmission and check the machined faces of the center case. Paying particular attention to the areas between the ports. that is where the oil can escape and not hold pressure and that loss of pressure is the reason you could be experiencing low power. As always, you can call the service department to talk to the friendly techs at 866.572.3441 and see if they can help troubleshoot your issue.
Johnny Williams says: I have a craftsman riding mower model 917 288561 with 150 hrs. The k46 transaxle went out and have a new one coming soon.Do i need to purge it after installing and do oil changes every 200 hrs. or so with 5w50 synthetic.I mow normal with it at home but yard has some hills and is sloped for the most part.
-
Hello Mr. Williams,
Our Transmissions are tested at the end of the assembly line to ensure that they are meeting certain standards. So your transmission that is coming is purged, tested, and ready to drop in your tractor.
Steve Kariker says: I just inherited an 02 John Deere LTR 180 with a tuff torq K46 transaxle. Everything is working fine but there is a little humming noise when I engage the transaxle. The article above seems to contradict itself in regards to an oil change. First paragraph says “Normally the Strider™ transaxle (K46), that is featured in many tractor & rider models, does not require any servicing for the life of the vehicle.” Then “In heavy usage applications oil changing is recommended after the 1st 50 hours of operation and every 200 hours, thereafter.” What is “heavy usage?” and should I take the transaxle out and change the fluid? Thank you so much!
James French says: I have a 11 yr. old, 400 hrs. K46 in John Deere LT160, should I remove it and change fluid and was told to use 5w50 synthetic motor oil if I do !!
-
what type oil for al,winter ,summerl year
-
Hello Mr. French,
Yes, changing the oil is a good idea. The oil in the transmission will breakdown over time and keeping fresh oil in the transmission will definitely help it run. We do recommend 5W-50 synthetic oil for your change and have an excellent blend that will help the unit run longer. You can always contact the helpful techs at the Service Department if you have any further questions.

RL Golden says: I own the John Deere L-120 and the transmission has failed. Imagine that? Any design that requires you to have to remove the transmission to replace the fluid is pure BS. The John Deere Manual says, “The transmission is a sealed unit that requires no maintenance” To add insult to injury they want to charge me more for a replacement than the mower is worth, knowing it won’t last either? Last John Deere anything I will ever own.

Larry Conley says: I am having problems with my John Deere L130 tractor transmission slipping. Belt and pulleys are new. My tractor is a 2004 and is in very good condition. If I remove the transmission and change the oil can I drain most of the old oil from the top plug. I have observed someone trying to suck out the oil but he only got about a pint out. I may end up rebuilding or replacing the transmission but I would like to try oil first . If I have to replace the transmission should I upgrade to a k66 or another k46. If I have to replace the transmission I will contact you for what transmission will fit my tractor.

Hello,
I would need a little more information to help you. I need the serial number of the pump to know which one it is so I can get you the information on oil.
