This clutch assembly engages and disengages the rear three-point hitch on the host tractor. It sits between the hydraulic control valve and the lift arms, transmitting torque to raise or lower the implement. When the clutch wears or slips, the hitch fails to hold position under load or drifts downward during operation. As an original-manufacturer component, its internal friction surfaces match the original stack height and spring preload, so the engagement timing and holding torque remain as the system was designed. On reinstallation, verify the linkage free play and bleed the hydraulic circuit to remove trapped air.
