摘要： Method and apparatus for pulling a vehicle free from mud, etc. using a vehicle drive wheel as a windless or winch and employing an elongated flexible strap, a gripper plate mounted on a leading end of the strap and an anchor plate mounted on a trailing end of the strap. The gripper plate is inserted between the tire and its support surface with upstanding teeth of the gripper plate engaging the tire. The drive wheel is then rotated with the vehicle engine to draw the gripper plate around the tire and wrap the trailing strap around the tire. The gripper plate is then secured to the overlapping strap, the anchor plate is anchored at a remote point aligned with the drive wheel and the vehicle is driven towards the anchor point using the strap to pull the vehicle free.
