POWERTRAIN
Transmission Planetary power shift with three forward and three reverse gears operating with robust oil-cooled clutches. The modular transmission easily slides in and out of the rear case for service. Clutch packs are oil cooled for extended service life. A decelerator pedal controls ground speed from maximum to stop.
Torque Converter Power separating hydraulic mechanism, single stage converter for high reliability and performance. Torque converter is matched to engine output to achieve superior dozing capability.
Steering Twin lever wet clutch steering, multi-disc spring loaded, hydraulically separated control. Responsive and reliable maneuverability in any condition.
Final Drives Elevated sprocket, two stage planetary reduction gear, sealed and splash oil lubricated. The segmented sprocket design allows ease of service and disassembly.
Brakes Spring-applied, hydraulic pressure released, oil cooled brake clutches assure excellent braking power and control and prevent slippage, even on challenging slopes.
