摘要:
An extensible and retractable, split hitch construction which offers articulative versatility in aligning the hitch with the ball or other hitch connection of a towing vehicle. Accordingly, rather than requiring an exact alignment of the trailer tongue with the tractor ball, for example, the tractor is merely brought in proximity with the hitch connection. Thereafter the tongue of the hitch is extended and pivoted as necessary to come into proper vertical alignment with the ball or other tractor connection. Means are provided in the hitch construction for the gradual application of brakes to the towed trailer where the same presses toward the tractor.
