In agriculture, construction and even military applications, pintle hitches are the trusted product of specialized towing. They are notorious for their high weight capacity and simple design. The basic pintle hitch is essentially a hook and loop, with the hook attached to the vehicle and the loop mounted on the trailer. Because of their simple design, pintle hitches are able to have thicker metal construction and more secure coupling.
