Abstract
An impeller is mounted above the top wall of the housing of a mower carried by a riding vehicle, near the side of the mower at which it has its clipping outlet. The rotor of the impeller rotates on a vertical axis that is between the clipping outlet and the vertical axis of the mower blade nearest that outlet and is driven by a belt engaging a pulley on the spindle for that blade. Flat paddle-like blades of the rotor have a portion of their orbit in an upwardly and rearwardly extending passage defined by the front portion of a clipping duct that communicates the mower clipping outlet with a receptacle at the rear of the vehicle. The impeller draws air and clippings out of the mower housing and propels them rearward through the duct.
