ABSTRACT:
A towing apparatus for releasable securement between a wheel, or wheel gear, or wheel support structure, of an object-to-be-towed and a towing vehicle. A hitch connection is releasably secured to an elongated, resiliently bendable draft member at one end, and to an adjustable torque engaging member at the other end. A breakaway sleeve is secured to the bendable draft member in proximity to the torque engaging member. A breakaway support member having upper and lower bracing bars is pivotally secured to the breakaway sleeve, to provide arcuate travel of the bendable draft member. Limit stops extend between braces, to limit the arcuate travel of the bendable draft member to not more than 30 degrees. An expandable yoke is secured to the upper and lower bracing bars to provide an apparatus to releasably secure the towing apparatus to the object-to-be-towed.
