Abstract
A sweeping machine for mounting to a blower is adapted for sweeping debris, e.g., snow, from an area around an obstacle, e.g., fire hydrant. The sweeping machine comprises a rotating brush having an axis of rotation which is horizontal, a frame for the rotating brush, an arm extending from a proximal end to a distal end to which the frame is secured, a blower, and a pivoting mechanism secured to the blower. The pivoting mechanism is adapted to swivel the arm upwardly to lift the rotating brush and to swivel the arm within a horizontal plane to move the rotating brush horizontally relative to the blower. Thereby, the sweeping machine is adapted to sweep debris from the area around the obstacle by the rotating brush toward the blower which is itself adapted to blow the debris away from the obstacle.
