Torque Converterand Transmission
Torque converter of the bulldozer has single-stage, three unites structure.
Our bulldozer has a stable power output which is of high performance.
Its planetary type power shift transmission is of three speeds forward andthree speeds reverse, which makes the shift of speed and direction quicker.
