Abstract: A machine for removing a material mounted to an underlying surface from the underlying surface is disclosed. The machine includes a frame body, an assembly for propelling the frame body relative to the surface, a plate carried by the frame body and a blade assembly pivotally coupled to the plate. The plate is movable relative to the frame body between a deployed position for removal of the material from the surface and a stored position with the plate positioned for unrestricted movement of the frame body relative to the surface. The blade assembly includes a removal blade for removing the material from the surface. The blade assembly is movable between a plurality of positions with the blade oriented at an angle relative to the plate, and is secured in a selected one of the plurality of positions during removal of the material from the surface.
