Abstract: A harvesting header for traversing a field to perform a harvesting operation includes a first frame assembly adapted to be coupled to a work machine and a second frame assembly suspended forward of the first frame assembly. The second frame assembly may pivot relative to the first frame assembly. A suspension system is coupled to the second frame assembly and provides a suspension force to the second frame assembly. A controller is operably coupled to the suspension system, and a slope detection system is disposed in electrical communication with the controller for communicating a slope of the field to the controller during the harvesting operation. The controller operably controls the suspension system by adjusting the suspension force based on the slope of the field.

Abstract: A harvesting head height control circuit (162) for controlling the height of an articulated harvesting head (104) that is supported on a combine harvester (102) during harvesting in an agricultural field includes an ECU (164) configured to raise and lower the portions of the articulated harvesting head. The ECU (164) receives signals indicating the magnitude of a rearward force acting upon the articulated harvesting head and automatically changes the commanded operating height of the articulated harvesting head (104).

Abstract: A method of controlling a multiengine harvester including the steps of operating the harvester in a first mode, operating the harvester in a second mode, and selecting less than all of the power absorbing loads to be driven. In the first mode, the harvester is operated using a first engine and a second engine to drive the plurality of power absorbing loads. In the second mode, the harvester is operated with the second engine being uncoupled from all of the power absorbing loads. In the selecting step, less than all of the power absorbing loads are selected to be driven dependent upon the sensed load on the first engine while operating in the second mode. The first engine is incapable of driving all of the power absorbing loads.
