Derating the engine of a combine in response to usage

摘要

An agricultural combine having an internal combustion engine for driving the various assemblies on the combine. An electronic engine controller is used to monitor and control the operation of the engine. Sensors provide inputs to the electronic engine controller. In response to the inputs from these sensors the electronic engine controller controls the output of the engine. The straw chopper, the propulsion assembly, the separating assembly and the harvesting assembly are provided with on/off switches that are in communication with the electronic engine controller. These on/off switches located in the operator's cab of the combine which are used to activate these crop processing assemblies. In response to an off signal by one or more of these switches the maximum power level is decreased accordingly.
