Title: Header flotation and lift system with dual mode operation for a plant cutting machine

Abstract: A method and system for controlling the operation of a header lift and flotation system for a plant cutting machine, which provides dual modes of operation, including a first mode allowing operator settable and controllable header height with an upward floatation or up-float capability, and a second ground contact mode having a full (up and down float) capability. The system is automatically operable for switching between the two modes responsive to predetermined input commands, and can automatically calibrate for changes in the header weight so as to provide consistent float function and feel.
