Abstract An engine-transmission control system having an engine associated with a variable hydrostatic transmission with a ratio governor valve to set the transmission ratio and, thus, control engine speed, a horsepower demand signal valve and an engine speed signal valve with the signals derived from these valves being applied in opposition to the ratio governor valve for control thereof, and an engine fuel governor for the engine providing an operating curve for the engine which relates engine speed to engine horsepower to cause operation along the locus of minimum fuel consumption for the engine whereby operation of the transmission to set the engine speed determines engine horsepower by operation of the engine along the operating curve. The system includes first linkage means associating an accelerator pedal with the horsepower demand signal valve and the fuel governor to provide a range of movement for the horsepower demand signal valve greater than that of the fuel governor. A lost motion connection in the linkage means permits operation of the fuel governor in advance of the horsepower demand signal valve upon initial movement of the accelerator member. Second linkage means associated with an engine brake member enables control of the horsepower demand signal valve without movement of the fuel governor and is interrelated with the first linkage means whereby one linkage means may operate independently of the other.
