ABSTRACT:
An adjustable length drawbar assembly includes a cage which is pivotally attached to the rear of a vehicle and a drawbar which slides in the cage. A plurality of spaced apart bores extending laterally through the drawbar. A pair of claws are mounted to a selected one of the bores by a pin and springs bias the claws towards the drawbar. A pair of recesses are formed at the rear end of the cage adjacent to a pair of ramp surfaces. The claws are spread apart as they slide over the ramp surfaces, and the claws have tabs which are received by the recesses to releasably lock the drawbar into the desired position with respect to the cage. The claws may be pulled away from each other and out of the recesses, and then rotated on the pins 90.degree. to disable the locking mechanism.
