Product advantages

More reliable-high configuration, low failure rate

  • Global procurement, select domestic and foreign famous suppliers for parts and components, effectively improve reliability and reduce failure rate.
  • The 93 sand dust filter adapts to various environments such as dusty and different soil quality, extending the maintenance period of the main filter element and reducing user operating costs.
  • The crankshaft is made of forged steel, which has higher strength.
  • Integrated fuel filter to facilitate vehicle layout and maintenance.

    • More efficient-strong power and high efficiency

  • High speed and constant power, low speed and large torque, good acceleration.
  • The torque reserve rate is as high as 25%, which is more suitable for the soil quality and agronomic requirements of different regions, and the work efficiency is high.

    • More economical-accurate fuel control, low fuel consumption

  • Optimize supercharger, fuel injector and calibration ECU data, through flexible control of fuel injection pressure, realize multiple injections, reduce engine fuel consumption and improve combustion efficiency

    More comfortable-low vibration and noise 

  • Large-flow water pump and low-speed fan effectively reduce cab noise and avoid driving fatigue.
  • Controlled by the electronic control system, the fuel injection pressure is more stable, the response is fast, the fluctuation is small, and the combustion noise is low.

    • Smarter-real-time monitoring, remote control 

  • Installment management, which can locate and remind payment at any time for the whole machine that implements installment payment.
  • Fuel consumption management, real-time recording, monitoring, and storage of engine real-time fuel consumption and comprehensive fuel consumption.
  • Vehicle speed management, real-time recording, monitoring and storage of real-time vehicle speed.
  • Positioning management, can locate the position of the whole machine, and accurately grasp the position information of the whole machine.
  • Security and anti-theft, can track and locate the stolen agricultural machinery, and remotely lock the agricultural machinery.
  • Abnormal reminder, real-time monitoring of engine operating parameters and early warning of hidden troubles.
  • Remote diagnosis, automatic fault alarm, remote engine fault analysis and judgment.　

    • More adaptable-complex environment, flexible response 

  • Adapt to various environments with high temperature, dust and different soil quality.
  • Good cold start, smooth start without any auxiliary measures at -10℃.

    • Cold start capacity

  • The air intake heater ensures the starting temperature at -25°C.

    • Drain interval

  • 500h oil drain interval.
