A ball hitch is disclosed for connecting a drawbar of an agricultural vehicle to a coupling pin of a trailer. The ball hitch comprises a ball element having a part-spherical outer surface and a cylindrical bore for receiving the coupling pin of the trailer. The socket element is constructed as a sleeve that is removably mountable in the drawbar and has a part-spherical inner surface within which the ball element is received to allow the coupling pin to swivel about mutually orthogonal axes relative to the drawbar.
