A handy device for retrieving a vehicle stuck in a snow bank with a metal shoe about the width of a tire and roughly conforming the radial curvature of the tire, multiple conical sharp or blunt projections on the under surface of the metal shoe that increase traction on snow or ice, a side plate attached to one side of the shoe at one end and with a hole at the other end, and, a right angled bar, one side of which has multiple small holes and passes through the hole in the side plate and other side of which passes through the existing gaps in the wheel rim, and, a metal pin that locks the angled bar into the hole in the side plate. A preferred embodiment includes wherein the side plate and the angled bar are laminated with plastic or such poor conductor of cold. An alternative embodiment includes wherein the side plate is hinged to the metal shoe on one side with or without the other side fixed through a hinge to the rim of the wheel.
