Abstract
A one-piece pintle hitch is disclosed. The one-piece hitch utilizes an integral drawbar that may be engaged with a conventional receiver assembly such as installed along the underside of a vehicle. The one-piece pintle hitch avoids the use of prior art mounting plates that bolt to one another. Accordingly, the problems associated with threaded fasteners such as loosening, fracturing, and corrosion are eliminated. In addition, the one-piece pintle hitch utilizes a unique configuration along its bar portion that results in a significant reduction in weight and materials.
