The machine includes an open wheeled carriage which carries a platform between its side rails and an engine is mounted on the platform to drive a rotary brush and to drive a blower mechanism. The engine platform is pivotably connected to the carriage for raising and lowering the rotary brush, and the outlet from the blower mechanism is fixed to the wheeled carriage immediately behind the rotary brush.
