    What is the difference in a K46CR an K46C

    • ggraham says:

      Hello,
      The K46C is sold to John Deere and the K46CR is sold to Husqvarna. Gearing is different, the fan and pulley stack up is different, axles are different lengths, and the K46CR has IDS whereas the K46C does not.

    I am looking for a rebuild kit for a Tuff Torq K55 transaxle. Serial number 021110. It is out of a 1996 John Deere STX38 with the black deck.
    Is that something that is still available, part number, cost?
    Thank you in advance for any help.

    I have a husqvarna lgt 2654 with a tuff torq k46 bn # 7a646084161. My question is i see the replacement k46bn has a number of 7a646084162. Is this just the new model and are they compatible.

  • I have a John Deere riding mower with the K46V transmission in it and have replaced the trans three times within 6 year time. I have a chance to get a k57 or a k66 type and was wondering if they would fit. I heard those two types are stronger transmissions.

  • John Engdahl says:

    I have a JD L110. Found a used transaxle on line with the same JD part number of AM131575 but the serial # is different (46V- 0064049 mine is 46V- 0089577). Both are TUFF TORQ K46V S/N: . Is it safe to assume that if the OEM part number is the same the transaxle will fit?
    Thank You

    • ggraham says:

      Hello,
      We do have some parts for that unit. it is a K61D according to Tuff Torq though Toro did call it the K61A for them. We do have a distributor for Argentina. Before you call or email make sure you get the serial number which is stamped on the top by the oil fill area. The CSR will need that number.

  • Dennis says:

    just purchased a K57R serial # 7A646084020.
    do you know what the factory oil is in it?
    with all the issues of the K46 wanted to use 20-50 synthetic oil

    • ggraham says:

      Hello,
      The K57R uses a version of 10W-30. 10W-30 is a conventional motor oil, however, it has enough additives to make it a unique item not to be found at retail outlets

  • Sidney says:

    Bought a Husqvarna Rider 120C which has a TUFF TORQ transmission. No oil is showing in the plastic transparent reservoir. How do I fill up the transmission to bring the oil up to the full level for: Tuff Torq 787T0024040 S/N: 36P-1026724
    HSQ/AB: PN: 585 23 52-01 what is the recommended oil.

  • Brian Mallory says:

    I have a 206 JD X300. After mowing up a small hill at my lake home for about 5 years the K46 transaxle was giving out. I bout an X320 for the lake home and took the 300 back to my permanent home where there is just a slight grade to deal with. I only have 300 hours on the X300 so I’d like to replace or re-build the transaxle. Which variation of the K46 is the best? I want to be able to change the oil easily. Is there a stronger, more powerful replacement for my K46 that will fit my X300?

    • ggraham says:

      Hello,
      Unfortunately, K46’s are configured to be in the tractor that they are installed in. They do not swap from one tractor to another without issues. You would need to know which K46 you have in your X300 because there are several different versions of the tractor and they all use different K46’s. There is a bar code sticker on the case of the transmission and on that sticker is a serial number following S/N. Get the serial number and that will tell you which transmission you have. Then you can search for it on the website (https://tufftorq.ordertree.com/) and find the parts you need.

  • Peter says:

    Are all axles on K46 the same spline count? Can I use an axle that is for a K46BR in a K46CR?

    • ggraham says:

      All the splines are the same, however, the length of the axles is different thus it makes it an ill-advised idea to use axles from a K46BR on a K46CR.

  • James Holloway says:

    Which transaxle comes in John Deere lt190.Is the part number on the transaxle or where do I find the information.

    • ggraham says:

      Hello,
      According to the JohnDeere website, it is the K46HD. You should be able to locate a bar code sticker on the case of the transmission close to one of the axles and on that sticker the serial number should start with 46HD. That will verify that it is the K46HD.

  • BEN HOLDEN says:

    Will 1A646034141 Transmission Right axle fit my TT# 7A646084091 S/N 46AW0106233?

    • ggraham says:

      Hello,
      That number 1A646034141 is a part number for a case. I cannot tell you which transmission that is because a case part number is not a unique identifier for the transmission because it is on all the cases.

  • Ken Cullipher says:

    I have a Tuff Torque P/N 7A646024390 JD P/N: AM131580 S/N: 46AC0197911. I need to replace this transaxle as it has started jerking and jumping when turning. I would like to know what newer models that would be very similar as this is a 2004 I believe. Most transaxles with that JD part number will likely have high usage also. Can you refer me to some information that will help me maneuver through the model numbers, part numbers,cross reference charts, that would let me be able to look for the newest possible replacement?

  • Freddy Nash says:

    i have i believe a k57 not sure it is on a simplicity rider 16hp vanguard vtwin and i believe 38 inch cut my question is can you replace the input shaft without having to take the trans case apart

    • ggraham says:

      Hello,
      For a K57 you would need to split the case. There is a pin that runs the charge pump and is through the shaft internally. You have to remove that pin to be able to get the shaft out.

  • Randy Andrew Danielson says:

    Can you replace a tough Torx t40 with a tough Torx k62 on a John Deere l118 lawn tractor?

    • ggraham says:

      Hello,
      Not without major modfications. The simple reason being that our transmissions are built for the specific tractor that they are installed in. There are a number of variations that could make it difficult to impossible to replace one transmission with another. Not the least of which, in this case, is the size difference.

      Hello,
      I do not believe that the motor housing caused this, either. Depending on which K55 you have there could be a kit to replace the input shaft.

    • ggraham says:

      Hello,
      That is a strange occurrence. I would check the shock absorber that is on the control arm to be sure it is working correctly. Otherwise, It could be a linkage issue and you will want to check that as well.

  • James Britts says:

    Good morning.
    I have a 7A632084610 model K62v in my garden tractor. Will a 7A632084621 model K66y be a heavier duty direct bolt in replacement unit? If not, why? What do the V and Y suffixes indicate? All external dimensions seem to be the same.

    • ggraham says:

      Hello,
      Since the K62V is sold to John Deere and the K66Y is sold to Husqvarna the axles could be very different lengths. But the real difference is that the logic is opposite between the two transmissions and if you install the K66Y where the K62V is and hit the forward pedal it will go in reverse. Also, I do not see the fan and pulley on the K62V as John Deere put there own on the unit. so I do not know how different those are, either. We do not recommend swapping transmissions because these transmissions are built for the specific tractors that they are installed in.
