    Abstract: A winch pulley accessory for directing the pull of a vehicle-mounted winch to move a motor vehicle in any desired direction. The pulley accessory comprises an elongated tubular member and a pulley block. The tubular member slides into a box hitch mounted on the front of a vehicle. The pulley block is attached to the end of the tubular member. The pulley block has a sheave rotatably mounted on a pin. The pulley accessory allows a front-mounted vehicle winch to pull the vehicle backwards by sliding the pulley accessory into the hitch with the pin oriented horizontally and extending the winch cable under the vehicle, or laterally by sliding the pulley accessory into the hitch with the pin oriented vertically. The pulley accessory is lightweight, easy to install, and easy to remove for transport.
