Abstract
A hitch apparatus has a tongue member with a weight bearing surface and an opposite free surface, and defining a bushing hole extending substantially vertically. A bushing has a cylindrical portion defining a drawpin hole with an outside diameter equal to an inside diameter of the bushing hole and a flange extending outward from one end of the cylindrical portion. The flange has a tongue surface adjacent to the cylindrical portion of the bushing, and an opposite wearing surface. The cylindrical portion of the bushing extends into the bushing hole such that the tongue surface of the flange bears against the weight bearing surface of the tongue member, and the bushing has a Rockwell Scale hardness greater than a Rockwell Scale hardness of the tongue member. Different bushings may define a variety of drawpin hole diameters to suit different drawpins.
