Title: Friction-driven rotary push broom

Abstract: A rotary push broom provides a geometry between the centerline of the broom's wheels and the centerline of the broom's cylindrical brush that allows the vertical height of the cylindrical brush relative to that of the wheels to be adjusted as the frame rotates. The broom includes a support stand that allows the broom to be stored in a way that does not put the broom's weight on the brush. The broom also includes a ratchet gear system so that the broom rotates along with the wheels when the broom is operated in a forward sweeping direction and spins independent of the wheels when the broom is operated in a rearward direction. The gear system should be arranged so that the cylindrical brush rotates slower than the wheels in the sweeping direction. The support stand can be integrated with an endplate that accommodates the wheel connection and ratchet gear system.
