ABSTRACT:
Grass collection apparatus for attachment to a rotary power mower includes a platform mounted behind the mower and carrying thereon a grass container comprising an open-ended wire mesh cylinder, the lower end of which has removably attached thereto in surrounding relationship therewith a disposable plastic bag which is folded between the platform and the container. A stream of air and entrained grass clippings from the blade housing are directed by a conduit upwardly into the container through an inlet near the bottom thereof and against a perforated deflector comprising two concave sections intersecting in a cusp-like ridge disposed centrally of the inlet path. The deflector is inclined upwardly and inwardly of the container and is provided at the upper end with a downturned hood portion and operates to split the stream of air and entrained grass clippings to prevent the buildup of back pressure and to prevent the clippings from exiting the top of the container.
