ABSTRACT:
A mulcher attachment for use with a rotary mower for shredding and mulching the clippings produced during operation of the mower. The mulcher attachment comprises a circular disc mounted on the drive shaft of the rotary mower for rotation alongside the mower blade. A plurality of relatively large openings are provided at spaced locations around the disc with an upwardly extending impeller blade adjacent each of the openings and serving for inducing a flow of air upwardly through the openings as the disc rotates while drawing clippings, leaves and other waste therewith. A series of shredder blades are integrally formed along the peripheral edge of the disc and have cutting edges extending above the upper surface of the disc adapted for shredding and mulching the clippings, leaves and other waste as these materials are cast centrifugally outwardly during rotation of the disc. A cutting edge may also be provided along the uppermost edge of each impeller blade for cutting and shredding the materials drawn upwardly through the openings during rotation of the disc.
