Abstract: A hitch for connecting a trailer to a vehicle, especially a motorcycle or land-roving vehicle. The hitch comprises two couplings, including a conventional ball member adjacent one end, and a ball-bearing assembly located intermediate the ball member and the means for attaching the hitch to the vehicle. The ball-bearing assembly is capable of rotational movement about a horizontal axis for a full 360 degrees. The hitch thus provides unlimited rotational movement between the vehicle and the trailer in addition to the conventional pivotal movement provided by the ball member coupling.
