A pair of connecting bars is attached to the yoke and to the vehicle being towed. A lock assembly is connected between the yoke and the drawbar. The lock assembly is adapted to move from a first position in which the drawbar is free to rotate and a second position in which the drawbar is retained to the yoke.
