ABSTRACT:
A towing hitch having an arm arrangement including a first arm mounted on a vehicle, such as a lawn mower, to be towed and a second arm connected to the first arm and attachable to a towing tractor. Biasing the second arm toward the vehicle being towed is a resilient arrangement which causes the towing tractor and vehicle being towed to travel in parallel, but offset, paths, while a bumper assembly provided on the arm arrangement contacts obstructions, such as trees, in the path of travel of the vehicle being towed so as to change the angular relationship of the first arm and second arm against the bias of the resilient arrangement and route the vehicle being towed around the obstruction.
