The main shroud has dust and debris outlet disposed between the left end and the right end, a substantially hollow interior and a bottom opening. A first baffle is disposed within the substantially hollow interior of the main shroud. The first baffle is movable to any selected one of a plurality of flow positions, including a full flow position and a minimized flow position. A first control mechanism is connected to the first baffle for permitting selective control of the flow position of the first baffle.
