Mulching apparatus for a lawnmower

摘要

A mulching device for attachment to a lawnmower includes a cutting assembly separate from the mower blades, wherein the grass clippings are finely cut and then dispersed onto the ground surface. In one embodiment, the cutting assembly includes an auger that compresses the grass clippings prior to cutting them. The mulching device may also include a separation chamber for separating the grass clippings from the forced air exiting the mower deck, so that the grass clippings may be cut in an environment separate from the forced air. In another embodiment, the mulching device includes a dispersion assembly for spreading the cut grass clippings onto a ground surface. The dispersion assembly may include a chute extending from the forced air outlet to a position adjacent the cutting assembly, wherein the forced air exiting the separation chamber is directed onto the cut grass clippings to disperse the cut grass clippings onto the ground surface.
