Torque converter
Torque converter is power separating hydraulic-mechanic type
Transmission
Planetary, power shift transmission with three speeds forward and three speeds reverse, speed and direction can be quickly shifted.
Steering clutch
The steering clutch is hydraulic pressed, usually separated clutch.
Braking clutch
The braking clutch is pressed by spring, separated hydraulic, meshed type.
Final drive
The final drive is two-stage planetary reduction gear mechanism, splash lubrication.
