Abstract
A utility tow bar includes a coupler assembly, a pair of tow arms and fasteners for securing the tow arms to the coupler assembly. More specifically, the coupler assembly includes a tow arm receiving channel for holding the tow arms as well as a hitch ball receiving socket and hitch ball lock for connecting the utility tow bar to a towing vehicle. Preferably the tow arms are substantially S-shaped. Each tow arm is connected at its proximal end to the coupler assembly. Each tow arm includes a connector at its distal end for connecting to a trailing vehicle. Two sets of aligned mounting apertures are provided in the coupler assembly and tow arms. A pair of pull pins are received in the aperture sets to secure the tow arms and coupler assembly together. Pin clips secure the pull pins in position.
