BALL SOCKET ASSEMBLY FOR A WORK VEHICLE

A work vehicle with a chassis, a ground-engaging blade movably coupled to the chassis via a ball and socket assembly to allow the blade to pivot relative to the chassis. The ball and socket assembly comprises a semi-spherical socket with at least a first circular groove on a surface of the socket positioned coaxially with a centerline axis of the semi-spherical socket, a second circular groove concentric and spaced apart from the first circular groove along the surface of the socket, and at least two interconnecting grooves coupling the circular groove and the second circular groove; and a ball member disposed within the socket.
