ABSTRACT:
Several embodiments of vehicles having automatic or manual speed control. The manual speed control permits the operator to control the speed of the engine and the automatic speed control is effective when a power takeoff shaft is being driven for automatic speed control under this condition. In each embodiment, the automatic speed control includes a governor that is driven only when the power shaft takeoff is being driven. In one embodiment, a throttle valve controls the engine speed and the manual and automatic speed controls alternatively operate the throttle valve through selectively engageable couplings that are operated in response to shifting into and out of the power takeoff mode. A number of other arrangements are also illustrated and described that provide different throttle valve arrangements for controlling the speed automatically or manually.
