ABSTRACT:
A dual implement hitch for pivotal connection to the drawbar of a towing vehicle whereby a pair of implements, such as rakes, tedders or the like may be selectively towed in one of several modes by a simple movement of an operator without disconnecting the implements from the hitch and reconnecting same in a different position. The hitch comprises an arched longitudinal frame having a clevis at its front end for connection to the towing vehicle. The rear of the longitudinal frame is rigidly supported upon an arched transverse from which is supported by dirigible wheels at its opposite ends. A first hitch element is provided at the front end of the longitudinal frame behind the clevis for pivotally connecting a first implement to the frame, beneath the arch. A second hitch element is provided at the rear of the longitudinal frame for pivotally connecting a second implement in trailing position behind the hitch. A tie rod maintains parallel relationship of the wheels. An operator is connected between the transverse frame and the tie rod for selectively moving the wheels to one of: a transport position with wheels parallel to the longitudinal axis of the hitch, a left offset position causing the hitch to track to the left, and a right offset position causing the hitch to tract to the right of the towing vehicle. Two side delivery rakes connected to the hitch may thereby be towed selectively in a transport mode, a single windrowing mode and a double windrowing mode.
