摘要

A tractor having a mounting assembly and a lift arrangement has a float module and a header on the forward end. The float module having adjustable and calibrated springs on the header which allows the header to float relative to the lift arrangement on the tractor. The float force is ad justed by raising and lowering the lift system in dependence on an angle measurement of the lift position. The angle measurement is provided a detector the raising and lowering of the lift system is accomplished with the aid of a control system responsive to the detector.
