This ball joint connects a hydraulic control rod to the actuator lever within the tractor's hydraulic system. It allows angular misalignment between the rod and the lever while transmitting linear push-pull force. Wear at the spherical contact surface introduces free play, which causes delayed or imprecise implement response. As an original AGCO component, the ball stud and socket are machined to the same clearance as the original assembly, so no shimming or bushing adaptation is needed during replacement.
