Benefits of Replacing Worn Top Link Pins
Worn or damaged top link pins can introduce excessive movement into the hitch assembly, accelerating wear on linkage components and reducing implement stability. Replacing worn pins helps restore a secure connection, improves implement control and contributes to safer operation in both field and transport conditions.
Installation Tip
Inspect the top link ball, retaining hardware and implement mounting points before installation. Replacing worn linkage components together will maximise service life and maintain correct hitch alignment.
