Abstract

A harvester implement includes a linkage system supporting a harvester head, and a float system having an internal fluid pressure that is controllable to achieve a ground contact force between the harvester head and the ground surface. A controller is operable to receive a user defined input commanding a desired ground contact force, and define an initial value of the internal fluid pressure to achieve the desired ground contact force. The controller may then automatically detect a change in an operating parameter of the harvester head during operation, and automatically re-define the initial value of the internal fluid pressure to provide an adjusted value of the internal fluid pressure to maintain the desired ground contact force based on the detected change in the operating parameter of the harvester head during operation.
