This hitch pin is the original equipment component that secures the trailer coupling to the tractor's three-point hitch or drawbar system. It transmits the tensile load from the towed implement through the hitch assembly into the tractor chassis. A worn or undersized pin introduces play in the coupling, which can lead to unintended uncoupling or accelerated wear on the hitch clevis and locking mechanism. As an AGCO-manufactured original part, the pin is machined to the same diameter and length tolerances as the factory assembly, ensuring the locking mechanism engages fully without excessive clearance. On installation, verify that the retaining clip or cotter pin seats fully in the cross-hole to prevent the pin from walking out during operation.
