A snow shovel apparatus comprises: a) a frame having an extending handle, an upright post extending from a front portion of the frame, said post having an upper end portion having a slide stop, and a central portion having a lower slide and an upper slide, and a lever having a central portion hinged to the frame, a rearwardly extending end portion, and a forwardly extending slide lift end portion, attached and configured through a slide lift connection means to lift the lower slide when the rearwardly extending end portion is depressed; b) a shovel portion having a bottom snow carrying portion and an upright back portion; c) a lower shovel arm having one end portion hinged to a lower portion of the upright back portion of the shovel portion, and having the other opposite end portion hingeably 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 portion and having the other end hingeably connected to an upper end portion of a pivoting arm, said pivoting arm having the other end portion hingeably 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 lift end portion of the lever the shovel portion is first lifted up the post, and then when the top slide is prevented by the top stop from further upward sliding, the bottom slide continues to move upwardly, causing the other ends of the lower arm and the pivoting arm to move together, thereby causing the shovel portion to extend outwardly and turn from a snow collection to a dumping position.
