Abstract
Abstract An attachment member having a cross bar and a pair of legs is attached to the under side of a vehicle to be towed in such a manner that it is attached to the rear of the rear wheel axle and also in front of the rear wheel axle with the legs extending beneath the axle so as to be clear of the axle when the vehicle is resting on all four wheels. When it is desired to tow the vehicle a tow bar is fitted to the attachment means at two positions with the rear end of the tow bar protruding to the rear of the towed vehicle. The legs of the attachment member are provided with sliders which can be moved to positions beneath the axle so that when the rear end of the tow bar is raised, the sliders engage the under side of the rear wheel axle and the vehicle is lifted.
