ABSTRACT:
An assembly for drawbar retention from a hanger bar on the rear of a tractor includes bottom and top capture plates spanning the intersection of the drawbar and hanger bar, front to back and side to side, and held together by four bolt and nut fasteners that are passed vertically through the four corners of the two plates such that there are two bolts on either lateral side of the drawbar and two on the front and back sides of the hanger bar. A pair of spacer blocks are provided across the front and back edges of the hanger bar releasably captured between the cover plates by the bolts. Cutouts in the spacer blocks can receive tongues on wear pads to permit pads to be captured between the top cover plate and hanger and/or the hanger and the drawbar by the bolts and spacers. The method is the arrangement of top and bottom cover plates with spacers and fasteners as stated, with or without wear pads.
