Patent ID: 8185278

Claim:
An engine speed control system for an agricultural vehicle, the system comprising: a throttle controller for selecting a variably adjustable engine speed; a mode selector for selecting between a plurality of pre-set engine speeds; and a control device responsive to the throttle controller and the mode selector for generating engine speed commands and delivering the engine speed commands to an engine controller for controlling the speed of the agricultural vehicle's engine, the control device being operable to generate a first engine speed command associated with one of the pre-set engine speeds when an operator activates the mode selector and to override the first engine speed command with a second engine speed command associated with the throttle controller when the operator activates the throttle controller, the throttle controller is being moved to a lower engine speed, and the throttle controller calls for an engine speed less than the pre-set engine speed, wherein the control device does not override the first engine speed command when the operator actuates the throttle controller and the throttle controller calls for an engine speed greater than the pre-set engine speed.
