Abstract: The hitching aid disclosed is for use with agricultural tractors. It is used to allow the tractor to be backed onto a trailer, whereupon the trailer becomes automatically hitched to the tractor. The aid includes a converging channel which receives the head of the trailer's draw-pin. The channel draws the pin-head into a throat, thus aligning the pin before the pin enters the pin-receiving jaws. Thus, any abusive loads due to mismatch, etc., are taken by the bulbous head of the pin and the channel, rather than by the shank of the pin and the jaws.
