Zusammenfassung:	An electronic engine speed control system is used on a work machine utilizing an engine with a governor control movable between a plurality of positions. The governor control is operated by an operator so that a desired engine speed may be selected for driving a plurality of wheels through a transmission. The transmission is specifically controlled to obtain a desired ground speed independent of the selected engine speed. The engine speed control system includes an electronic control module. An operator switch is connected to the control module and is movable to a set position which sends an input signal with a desired engine speed value corresponding to a selected engine speed to the control module. An engine sensor is connectable between the engine and the control module for sensing the speed of the engine and sending an input signal with an actual engine speed value to the control module. An actuator is connected between the control module and the governor control and responsive to a control signal from the control module for moving the governor control to any one of the plurality of positions. The control signal is delivered to the actuator as a function of the desired and actual values so that the engine speed is electronically set and maintained at the selected engine speed independent from the ground speed of the work machine.
