This automatic hitch assembly connects the tractor's three-point linkage to the drawbar or implement, allowing a tool to be coupled and uncoupled without leaving the cab. It mounts at the hitch point and uses a locking pin mechanism to secure the implement's drawbar eye around the hitch pin. A worn or misaligned locking pin can cause the hitch to release under load, leading to implement separation. The manufacturer machines the locking pin and hitch pin to the same diameter tolerances as the original assembly, ensuring the locking mechanism seats fully and the drawbar eye is held without play.
