Bulldozer
- The appearance of the vehicle is based on optimization design.
- Higher engine power reserves efficiency, bigger torque output, lower fuel consumption, while better reliability. Hydraulically controlled drive, automatically speed regulating and non-stop gear shifting.
- 3-element, single stage, single phase torque converter for higher efficiency and bigger capacity.
- The novel hexahedral cab offers excellent visibility, the powerful ventilation and unparalleled dust-free.
- The final drive uses triangle Spline and tip relief, crowned gear drive for enhanced balance and the stability during power transmission and added life.
- New blade is more durable and capacious.
- Alarming monitoring system is efficient and reliable.
- Implement controls are piloted to minimize operating effort.
