A tractor or utility vehicle used for agricultural work may be used for transport tasks and for carrying out tasks in the field. The tractor or utility vehicle can be coupled to an implement that has electoral couplers, hydraulic couplers, and/or a power takeoff that is connected to the tractor couplers and to the tractor power takeoff. Implements attached to a tractor or utility vehicle are generally not utilized full time, and thus a coupling mechanism is provided to allow for convenient connecting and disconnecting of the implement.
