Abstract: A hitch sling for aiding in coupling a trailer's socket to a ball mounted on a tongue extending from a tow vehicle comprises: a leg secured to the trailer and having a first roller located at lower end of the leg and below the trailer's socket, a winch, and a flexible line which extends from the winch, about the first roller and to a distal end, so that, when the distal end is secured to the tongue and the line shortened, the leg is lifted upwardly towards the tongue so as to position the socket substantially above the ball, and when the line is lengthened, the socket is lowered onto the ball for coupling. Preferably a second roller is positioned between the winch and first roller so as to direct the line along or through the leg to the winch.
