Abstract
A removable ball goose hitch system. The ball member includes a ball portion and a body portion. A plurality of locking ball bearings in the body portion are engaged by an internal plunger that is actuated by a screw that protrudes from the top of the ball portion. The locking ball bearings are adapted to be engaged with a receiver in the hitch mechanism on the vehicle. When the screw is unthreaded, the ball bearings are allowed to retract and the hitch ball can be removed. All moving parts of the mechanism are located in the ball member and improper hookups are prevented.
