Fuel filter system
- The three-level fuel filter is used, which has electric fuel pumping, fuel water separation and fuel filtration functions, ensuring good fuel adaptability. The high-mounted fuel filter is used, which is easy for maintenance and can be equipped with the three-level nanny filter element for easy layout and maintenance of the engine.
Cooling system
- The high-capacity water pump guarantees low noise and power consumption.
Drivetrain
- The double PTO structure and three speed ratio options (i.e., 1:1/1:1.13/1:1.24) guarantee the flexible arrangement of the hydraulic system.
Electronic control system
- The special “constant speed control”, a special throttle control logic, is developed to improve work efficiency and reduce labor intensity.
- The instantaneous speed change rate is low; the throttle response to sudden application of load is fast; the speed fluctuation is small; and the system runs smoothly during operation.
Long maintenance period
- 500h oil change period is ensured, reducing the usage cost.
Environmental adaptability
- The engine functions normally at -35°C ~ 50°C and more than 5,000m above sea level.
