    摘要： A shredder attachment converts a rotary power mower into a shredder for chopping or shredding leaves, clippings, twigs, small limbs, and other lawn and garden waste. The attachment includes a material receiving apron, an intake duct, and a plate which tightly engages the bottom of the mower housing to form a shredder chamber. An intake opening extends through the plate for admitting material to be shredded from the intake duct to a region of the chamber in which the rotary blade does not advance in the direction of the intake duct opening. A folding leg may be extended to raise the apron and duct so that the shredder attachment may be fed from an elevated position. In the first and second embodiments, the intake opening is at the rear side of the mower and the duct extends rearwardly of the mower; in a third embodiment, the intake opening is at the rear side of the mower and the duct extends forwardly of the mower from the intake opening. In a fourth embodiment, the mower housing remains horizontal and is elevated on its four wheels, the duct being formed from planar sheet metal segments for ease of fabrication, and the apron being pivotally mounted to the duct. The duct again includes a reentry ramp.
