Abstract: Microprocessor controlled automatic power control for adjusting the engine power setting in an engine-transmission power train in which the transmission drive reduction is variable in ratio, by step change or continuously so, such as for use in farm tractors. The microprocessor control monitors the position of this automatically moving lever and the desired transmission output speed to keep the setting adjusted so that engine power is set, within a deadband, to maintain a desired engine speed preferably resulting in minimum fuel consumption or in maintaining constant transmission output speed. Preferably, the microprocessor has a higher priority primary function of also automatically adjusting the transmission drive reduction ratio, for the same purpose but with higher sensitivity. The power control lever is specifically designed to automatically return the power setting to manual control as soon as the operator grabs the handle.
