AUTOMATIC HEADER HEIGHT CONTROL SENSED FROM FLOATING CROP ENGAGING MECHANISM

摘要

A combined electrical, mechanical and hydraulic mechanism in a combine harvester wherein the cutter bar rides on the ground and is mounted on the forward end of a frame member having its rear end pivotally attached to a cut crop receiving mechanism on the harvester. A feeler member mounted on the cut crop receiving mechanism contacts the frame member for actuating a control to raise or lower the cut crop receiving mechanism for maintaining the position of the cut crop receiving mechanism relative to the cutter bar. A manual control for raising or lowering the cut crop receiving mechanism is also provided.
