a) A frame having a handle, an upright post extending therefrom having a slide stop on an upper portion, a lower and upper slide on a central portion, a lever having a central portion hinged to the frame having a rearwardly extending end, and a forwardly extending slide lift end, attached and configured through a slide lift to lift the lower slide when the rearwardly extending end is depressed; b) a shovel having a bottom snow carrying portion and an upright back portion; c) a lower shovel arm having one end hinged to a lower portion of the upright back portion of the shovel, and the other opposite end hingably connected to the upper slide; d) an upper shovel portion projecting/dumping linkage, having an upper shovel arm having one end hinged to an upper portion of the upright back portion of the shovel and having the other end hingably connected to an upper end of a pivoting arm, the other end hingably connected to the lower slide and a central portion pivotably pinned to a central portion of the lower shovel arm. When the slides are lifted by the lever the shovel is first lifted up the post, and then when the top slide is prevented from further sliding, the bottom slide continues to move, causing the other ends of the lower arm and the pivoting arm to move together, thereby causing the shovel to extend outwardly and turn from a snow collection to a dumping position.
