Driving system

Torque converter: A torque converter is a 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 a hydraulically pressed, non-constant engaged clutch.                                  

Braking clutch: The braking clutch is hydraulic pressed by a spring, separated hydraulic, constant meshed type.                                         

Final drive: The final drive is a two-stage planetary reduction gear mechanism and splash lubrication.
