The power train of the harvester is a hydrostatic drive system. The harvester uses two drive loops to drive the machine.
The power train enables the machine to travel in many conditions. The power train utilizes pumps, motors, and valves in various combinations to obtain outstanding power train performance. These combinations are controlled by the IQAN monitoring and control system.
The power train has the following capabilities:
- All wheel drive control (six wheel harvesters)
- Brake control
- Differential lock control
- Directional control
- Speed control
- Traction control
The power train is composed of the following six systems that are controlled by the IQAN.
- Hydrostatic Drive System
- Charge System
- Brake System
- All Wheel Drive System
- Speed Control System
- Differential Control System
