Abstract
A tow bar apparatus has a hitch member, a pair of linkages, and a pair of tow bars. The hitch member has a receiver tube adapted to removably engage a towing vehicle, and a vertical pivot post having a vertical axis that is generally orthogonal to the surface when the hitch member is mounted on the towing vehicle. Each of the pair of linkages connects the hitch member to a proximal end of one of the pair of tow bars. Each linkage includes a vertical aperture that pivotally mounts the linkage on the vertical pivot post, and a horizontal pivot pin attached to one of the pair of tow bars. A towed vehicle attachment element of a distal end of each of the tow bars is adapted to be removably attached to the towed vehicle.
