ABSTRACT:
A riding debris mover for moving debris on a surface from a first location to a second location comprises a frame coupled to a riding platform adapted to support a user, and a plurality of wheels coupled to the frame comprising at least two opposing traction wheels for driving the riding blower. A power source is coupled to the frame and is operatively coupled with at least the two traction wheels, whereby the traction wheels are rotated independently and the riding blower is propelled. A blower assembly has an air inlet opening and an air outlet opening, the blower assembly being supported by the frame and operatively coupled with the power source, whereby the blower assembly generates a stream of air from the air outlet opening. A deflector assembly is associated with the blower assembly and comprises at least one movable deflector, whereby the at least one movable deflector can be independently moved between an open position, a closed position, and a position intermediate the open position and closed position, to control the air flow and air flow velocity of the stream of air generated by the blower assembly.
