This bushing sits in the rear three-point hitch assembly, acting as the wear surface between the hitch arm and its pivot pin. It absorbs radial loads from the implement and maintains the correct alignment of the linkage during lifting and lowering. A worn bushing introduces play at the pivot point, causing the hitch arm to drift laterally and reducing the precision of implement height control. This original part is machined to the same inner and outer diameters as the housing and pin, so it restores the original clearance without the need for shimming or reaming. On installation, ensure the bushing is fully seated in the bore and that the pivot pin rotates freely without binding.
