A method of controlling an output of an internal combustion engine having an electronic governor device and/or that of at least one variable displacement hydraulic pump driven by the engine in which, when the engine is operated in a range of high speed revolutions approximately equal to or exceeding the number of revolutions of the engine at a rated point on a governor control curve specific to the engine, the engine is operated by the action of the electonic governor device at a given point of a curve of equal horsepower of the engine where an engine output torque is higher than that in the high speed revolution range and where fuel consumption is lower than that in the range.
