摘要：A tractor has hydraulically driven wheels at a cab end and castor wheels at anengine end. It can be driven cab forward in a working mode with a header on the forwardend. It is rotated to engine forward in the transport position for more stable higher
speed travel. There is provided a float module with adjustable and calibrated springs onthe header which allows the header to float relative to the lift system on the tractor. Thefloat force is adjusted by raising and lowering the lift system in dependence on an anglemeasurement of the lift position. The lift system includes a lift cylinder and tilt cylindercontrolled to change cutter angle while maintaining a sight line to the cutter bar for theoperator.
