Manufacturer ID: K664
The K664 is not just an upgraded version of our popular 4WD IHT series of transaxles. These drive systems have been engineered from the ground up for the demands of heavier and more function-rich 4WD mower and articulating vehicle applications. Bigger and stronger pump and motor systems have been integrated to offer the power and control needed for bigger lawns and heavier loads. These units also include heavier axles, more gear options and better control flexibility. The K664 is an excellent choice to larger premium 4WD tractors and articulating ride-on mowers.
Patented L.O.G.I.C. case design for easy installation, reliability and serviceability.
Heavy steel axles for added strength and control.
Manual locking differential system (optional).
External hydraulic accessory support and charge pumps.
Larger pump and motor displacements provide the torque you need for ground engaging equipment.
