This pin serves as the pivot or connecting link within the three-point hitch linkage, transmitting tensile and shear loads between the implement and the tractor’s lift arms. It is positioned at the hitch point where the implement attaches, and its outer surface contacts the bushing or clevis bore during operation. Wear on the pin’s contact surface leads to increased clearance, which causes play in the hitch and can result in uneven implement lift or accelerated bushing wear. As an original-manufacturer component, the pin is machined to the same diameter tolerance as the original assembly, so no shimming or bushing replacement is needed to restore proper fit. On installation, ensure the retaining hole aligns with the locking mechanism and that the pin is fully seated before securing.
