Through the multi-functional control valve, the shift can be changed among 1st gear, 2nd gear, 3rd gear forward or reverse rapidly.
Steering and Braking Clutch
1. The steering clutch and braking clutch adopted in this bulldozer are adjustment-free, oil-type and multi-disc clutches.
2. The braking clutch is of spring-pressed, hydraulic separated, constant meshed type. The steering clutch is of hydraulic pressed, non-constant type.
3. While the steering and the braking clutches are operated at the same time, slow steering, sharp steering and braking can be realized.
4. The braking of the entire bulldozer can be achieved through the pedal.
5. Parking braking rod works to keep the undercarriage system in braking condition while the engine is started. It guarantees the machine not to slip on slopes when the engine is started.
