ABSTRACT:
The present invention is a hitch for coupling a towing vehicle to a vehicle to be towed. In one embodiment, the hitch comprises a receiver portion having a channel operably configured to receive an insert member and a connection portion disposed adjacent to the receiver portion and having a chamber with an orifice extending through the chamber, an edge defining an opening of the chamber, first and second notches disposed opposing each other along the edge, and first and second coaxial opposing flanges disposed about the orifice, within the chamber and apart from each other at a predetermined distance. Further the hitch may comprise a shaft having first and second ends, where the second end inserts into the orifice of the connection portion and the first end having a diameter larger than the shaft such that it forms a plate surface on the connection portion. In an alternative embodiment, the hitch includes a receiver portion having an integral ball mount.
