Abstract

The device includes a blade and a handle whereby the device may be used as a conventional snow pusher. Skis or skids below the blade support the blade at an angle relative to the ground, and may raise the blade 5 cm or so off the ground surface, so that the blade does not snag the ground during pushing. Left and right struts support the skis from the blade. The struts are collapsible, and when collapsed the skis lie tucked away against the back of the blade, whereby the device may be used as a shovel.
