ABSTRACT:
A dolly and method of use allow a disabled tractor to be efficiently and safely towed to a distant location. The dolly includes a ramp whereby the tractor can be easily rolled onto the dolly and secured thereto by tie-down chains. The method of use includes the steps of towing the dolly by wrecker to the disabled tractor, disengaging the dolly from the wrecker and connecting the wrecker to the tractor. The tractor is then urged by the wrecker up the ramp of the dolly where it is then secured. Electrical and pneumatic lines are connected from the wrecker to the dolly to operate brake lights, warning lights and the brake system of the dolly as conventional with trailers so the tractor can be safely towed to a distant location.
