Abstract
A method for use with an apparatus such as a tractor having an engine and an output device, such as a mower deck or snow thrower, comprising the steps of determining a rotational direction of a rotatable shaft as one of a forward direction and a reverse direction and selecting the operational status of the output device as one of an engaged state and a disengaged state, where the operational status is in the disengaged state when the shaft rotates in the reverse direction and is in the engaged state when the shaft does not rotate in the reverse direction.
