Abstract
A wheel lift towing apparatus includes a crossbar with opposing end portions; two collars, one being mounted to each crossbar end portion; two wheel retainer locating struts, one being connected to each crossbar end portion via one of the collars; and two wheel retainers, one being mounted to a free end of each of the locating struts. The wheel retainers each have a central arm with first and second wheel engaging elements disposed at the opposing ends of the central arm. The wheel retainer support structure associated with each strut is configured to position each wheel retainer so that the retainers' respective first wheel engaging elements are located below a center axis of the wheels of the vehicle to be towed and so that the retainers' respective second wheel engaging elements are located above the center axis of the wheels of the vehicle.
