Abstract: An agricultural vehicle includes a chassis and an engine, transmission and operator station which are each carried by the chassis. The engine has a maximum operating speed. The transmission includes a continuously variable output. A power/economy switch which is positioned within the operator station provides a first output signal indicative of a power mode and a second output signal indicative of an economy mode. A controller is coupled with each of the engine, the transmission and the power/economy switch. The controller receives the second output signal from the power/economy switch and controls each of the engine and the transmission to be in an economy mode, whereby an operating speed of the engine is limited to a reduced maximum speed which is below the maximum operating speed, and the continuously variable output of the transmission is increased to offset for the reduction in engine operating speed.

Abstract: The control of an apparatus within a grain holding device for feeding grain to an unloader conveyor operable for conveying the grain from the holding device, includes sensing a predetermined condition or conditions representative of capacity of the unloader conveyor for receiving grain, and adaptively controlling the apparatus for feeding grain to the unloader conveyor in advantageous varying manners responsive to the conditions, including to delay initiation of feeding until the receiving capacity is increased, and to match the grain feed to the capacity. The automatic control can be overridden, to allow user control of unloader speed, and can be configured to allow cleanout of the unloader conveyor.

Abstract: An unloader control for an unloader conveyor and grain tank conveyor of an agricultural combine, which, when an unload command is received, will automatically initiate operation of the unloader conveyor to commence conveying grain in an inlet end thereof toward the outlet end thereof so as to allow smooth transition of grain from the grain tank conveyer to the inlet end of the unloader conveyor, then automatically initiate operation of the grain tank conveyor for moving grain into the inlet end of the unloader conveyor, and, when a clean out command is received during operation of the unloader conveyor and the grain tank conveyor, will automatically cease operation of the grain tank conveyor, then, after a sufficient time period for the unloader conveyor to convey substantially all of any grain therein through the outlet end, automatically cease operation of the unloader conveyor.

Abstract: An integrated combine reel drive system for an agricultural vehicle such as a combine harvester, the drive system having the features of a single integrated hydraulic circuit for activating multiple hydraulic devices carried by the agricultural vehicle. The integrated circuit includes a header circuit, wherein the header circuit includes a steering circuit, an implement circuit, and a reel circuit. The header circuit includes two valve stacks for operating multiple hydraulic devices which enables the integrated circuit to drive the multiple hydraulic devices using manageable hydraulic pressures. Specifically, the integrated hydraulic circuit activates a hydraulic power steering mechanism, a hydraulic header adjusting apparatus and other hydraulic devices associated with the header, a hydraulic drive for the reel, and a hydraulic positioning mechanism for the reel of an agricultural vehicle.
