HITCH ADAPTER Abstract of the Disclosure A hitch adapter connects a tractor drawbar to an implement hitch pin and includes a cast housing having top and bottom walls and a forwardly open chamber that receives the rearward end of the tractor drawbar. The housing has a pair of vertical openings elongated in a transverse direction and receiving vertical bolts having nuts at their lower ends which are tightenable to clamp the housing between the head of the bolt and the nut. The shanks of the bolts are disposed on opposite ends of the drawbar and are shiftable laterally in the openings to engage the opposite side of the drawbar to limit lateral movement of the housing relative to the drawbar, the nuts being tightened to clamp the bolts in the selected position. Serrated surfaces are provided on both the top and bottom of the housing around the openings, and each bolt is provided with a pair of washers having serrated surfaces that respectively engage the serrated surfaces on the top and bottom of the housing. The serrations on said surfaces run in a fore and aft direction, and when the nuts are tightened on the bolts to clamp the serrations on the washers onto the serrations on the housing, lateral slippage of the bolts along the slot- like openings in the housing is eliminated.
