. An electronic engine speed control system for a work machine utilizing an engine with a governor control movable between a plurality of positions so that a desired engine speed may be selected and utilized for driving a plurality of wheels through a transmission, the transmission being controllable to obtain a desired ground speed independent of the selected engine speed, comprising:
an electronic control module;
an operator switch connected to the control module and movable to a set position which sends an input signal with a desired engine speed value to the control module;
an engine sensor 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 connectable 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 being 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 desired speed; and
means for disrupting the input signal between the operator switch and the control module so that the engine speed is no longer electronically set and maintained at the desired speed.
