ABSTRACT:
This disclosure relates to a trailer hitch for coupling a draft vehicle to a drawn vehicle wherein the eye portion of the hitch includes a molded insert of flexible material having an axial bore extending therethrough adapted to receive the pintle portion of the hitch in coupling relation. The flexible insert completely surrounds the pintle and thus maintains the pintle in spaced relation from the eye for yieldingly restraining relative radial movement between the pintle and the eye during all phases of operation, including flexing in the vertical plane when the trailer is negotiating inclined ramps or the like.
