Abstract
A method and apparatus for controlling engine speed during power take-off (PTO) operation. A technique is disclosed which enables accelerator pedal over-ride of PTO operation, wherein PTO operation is resumed when the accelerator pedal induced engine speed value decreases to a preset PTO engine speed. Also, a high-speed governor is employed to limit accelerator pedal-based engine speed during PTO over-ride operation to thereby limit maximum engine speed. In accordance with the invention, the operator of a vehicle can thus accelerate the engine, via actuation of the accelerator pedal, to engine speeds in excess of the preset PTO engine speed without disengaging PTO operation.
