  • Patent number: 4261115
    Abstract: A snowplowing blade includes a reverse scraping blade pivotally mounted to the rear surface of a conventional plow blade and supported such that when the conventional blade is lowered and moving in a reverse direction, the scraping blade is held in a stationary position at an obtuse angle with respect to a surface for removing snow from normally inaccessible areas such as the front of garage doors. When the conventional blade is moved in a forward direction during normal plowing, the reverse scraping blade pivots out of the way so as not to interfere with normal plow operation.
