Abstract
The present invention provides a speed control system for use in maintaining the rotational speed of an output shaft of a power takeoff unit within a predetermined range. A central control unit receives signals indicative of the speed of the input gear and, in response to the received signals engages and disengages the output shaft of the power takeoff unit. The central control unit also disengages the output shaft if the system's voltage levels drop below a preset minimum.
