This three-point linkage pin is the original AGCO component for the host tractor's rear hitch assembly. It functions as the pivot point connecting the lower link arms to the tractor chassis, transmitting draft forces from the implement to the tractor frame. Wear on the pin's bearing surface causes slop in the linkage, leading to uneven implement tracking and reduced accuracy of the draft control system. As an original part, its surface finish and hardness are matched to the bushing material in the link arm, preventing accelerated galling that a non-original pin could cause. On installation, ensure the retaining clip or cotter pin is fully seated to prevent the pin from walking out during operation.
