This hitch pin secures the implement drawbar to the tractor’s lower link, transmitting draft force from the implement to the tractor chassis. It passes through the clevis of the drawbar and the hitch clevis, with the cross-hole accepting a retaining clip or linchpin to prevent unintended dislodgement. As an original-manufacturer part, the pin is machined to the same diameter and shoulder length as the original assembly, so the retaining clip seats correctly without slop. A worn or undersized pin introduces play in the hitch, which accelerates wear on both the pin bore and the implement clevis. On installation, ensure the retaining clip is fully seated in the cross-hole and that the pin shoulder contacts the clevis face.
