ABSTRACT:
The vertically swingable header of a farm machine utilizes a flotation mechanism having a torsion bar as the source of lifting force. The torsion bar is mounted on the header rather than the base machine and is operably coupled with the base machine through loading apparatus that includes a cam and cam follower system. An alternative embodiment utilizes a cam track fixedly mounted on the base machine.
