Abstract: A mulching apparatus is described for converting green waste, including tree branches, small limbs, leaves, and grass clippings into a pulverized mulch. The apparatus comprises a green waste agitator hopper in the shape of an inverted, truncated cone, the hopper having a plurality of first blades fixed to an inner wall and projecting toward a vertical axis of the hopper. A waste agitator arm is rotatably mounted in the hopper through a bottom of the hopper for rotational movement about the vertical axis. The waste agitator arm has a plurality of second blades fixed thereto so as to intermesh with the hopper blades when the arm is rotated. A conduit is connected to a side region of the hopper to enable feeding waste material from the hopper to a fan mulching pulverizer disc rotatably installed in the conduit. The fan mulching pulverizer disc reduces the hopper waste material to a pulverized mulch and then blows the pulverized mulch out of the apparatus through a discharge duct.

Abstract: 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 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.
