A device for back scraping snow, earth, or other like substances which generally includes a truck having a concave snowplow blade mounted on its front. The blade has shoes provided on its backside, wedge shaped hinged connections mounted on the shoes, and a flat blade mounted pivotably on said wedge brackets. When the flat blade is brought in contact with snow to be scraped and the snowplow blade is moved in a backwardly direction, the snow to be scraped is moved by the flat blade.
