ABSTRACT:
An internal combustion engine is mounted on a frame supported by a set of wheels and has a shaft connected to drive a blower impeller. An annular plate is mounted on the engine surrounding the engine shaft, and a blower housing has a support ring which is secured to the plate by a releasable band clamp to provide for rotating the blower housing on the axis of the engine shaft. The blower housing has a center inlet and a laterally projecting tangential outlet, and a movable air deflector is mounted on the housing adjacent the outlet. The air deflector is actuated by an elongated control rod which extends from a handle assembly projecting rearwardly and upwardly from the frame, and the control rod permits the operator to actuate the air deflector when the blower outlet and deflector are located at either a high position on one side of the frame or a low position on the opposite side of the frame.
