ABSTRACT:
A control system controls the actuation of a plurality of control devices of a utility vehicle, including a PTO shaft control device. The control system includes a control unit which is electrically connected to the control devices and to switches for the manual actuation of the control devices. One of the switches is an automatic mode switch which controls activation of an automatic mode wherein the control unit automatically controls the control devices. In response to signals from a hitch switch, the control system transmits control signals to a hitch control which controls raising and lowering of an implement hitch. When the automatic mode is activated the control unit automatically disengages the PTO shaft if the hitch is raised above a pre-set hitch position. The control unit is also connected to an enable switch, and when the automatic mode is activated, the control unit automatically engages the PTO shaft if the enable switch is actuated approximately simultaneously with a lowering command generated by the hitch switch.
