发明名称 Roof ripper
摘要 A shingle removal tool includes a base, a forwardly extending blade, and a rearwardly extending shaft. A pair wheels are rotatable about a laterally extending axis located rearward of the blade. The blade has a planar portion forming a leading edge. The shaft has an obtuse angle forming a forward portion having a central axis which intersects the plane formed by the planar portion between the planar portion and the wheels and a rearward portion which intersects the plane formed by the planar portion forward of the planar portion. A rear grip can be mounted to the shaft either rigidly or for impact absorption and a fore grip can be adjustable along the shaft.
