Abstract

A dual mode trailer hitch that operates in both a 'vehicle-tow' mode and a 'manual tow' mode. In the vehicle-tow mode of operation, the trailer hitch is configured such that a trailer can be pivotally coupled to and towed by a towing vehicle, such as a tractor. In the manual-tow mode of operation, the trailer hitch is configured to not articulate, so that the trailer can be towed manually by a person. The trailer hitch includes bar pivot attachment member, a connecting link, a handle attachment fitting, at least one side plate, a tow bracket, and a vehicle coupling pin 23. In the preferred embodiment, the side plates are coupled on both sides of the tow bracket. The combined side plates and tow bracket are pivotally coupled to both the bar pivot attachment member and one end of the connecting link by a first pivot pin. The handle attachment fitting is pivotally coupled to the other end of connecting link by a second pivot pin. In the vehicle-tow mode, the trailer hitch is pivotally coupled to the towing vehicle by the vehicle coupling pin, which passes through apertures in the tow bracket.
