ABSTRACT:
A material removing apparatus includes a frame including a planar base portion and axially spaced front and rear portions. An elongated axle and a plurality of wheels are attached thereto and a plurality of rigid brackets are secured to the axle adjacent to the wheels. A contoured handle is securely mounted to the frame. The apparatus also includes a lifting plate extending forwardly from the bracket end portions and spaced forwardly from the wheels for lifting shingles upwardly and away from a support surface. The plate includes an inner shaft having opposed end portions for defining a fulcrum axis and an outer shaft journaled about the inner shaft and rotatable about the fulcrum axis in clockwise and counterclockwise directions. A mechanism is included for pivoting the plate about a selected arcuate path so that an operator can position the plate between the support surface and the shingles.
