<p>An electronic engine speed control system 10 for a work machine utilises a hydrostatic transmission 75 to drive and control the ground speed of a plurality of wheels 30 independent from an engine 35. The electronic engine speed control system 10 comprises a hydraulic pump 85 connected with the engine 35, a motor 80, a pressure signal line 90 connected between the pump 85 and the motor 80 for transferring hydraulic fluid at various flows therebetween so that the motor 80 drives the plurality of wheels at 30 various speeds responsive to the flow of the hydraulic fluid. A valve 110 is disposed within the signal line 90 which movable from a closed position to a plurality of open positions for selectively neutralizing the hydraulic fluid flow to control the ground speed of the work machine independent from the engine speed. The electronic engine speed control system 10 operatively associated with and located remotely from the hydrostatic transmission 75 for setting and maintaining the engine 35 at any desired speed during neutralization of the hydrostatic transmission 75.</p> |
