A chute and bag system for collecting leaves and other debris,
- said chute and bag being positioned on and in contact with a ground surface and being devoid of any attachment to a lawn mower or equivalent machinery,
- wherein the chute(30) has a front end(32) and a rear end(31),
- wherein the chute front end(32) has fixed and curved intake walls(50,52) to provide a Venturi effect for incoming leaves and debris,
- said chute front end further including a lower wall(55) extending between said fixed and curved intake walls(50,52),
- wherein the area above said chute front end lower wall(55) is completely open and devoid of handles or other equipment thus providing a more efficient intake to the chute and bag system,
- wherein the rear end(31) of said chute(30) comprises a generally rectangular area for economy of manufacture and includes a lower wall(38) and side walls(39a,39b) attached to said lower wall,
- said chute rear end(31) further including a top wall(37) having a handle means(35) mounted at approximately one-third of the distance along said chute rear end(31) to provide optimal lifting efficiency for the chute and bag combination,
- wherein said chute rear end(31) further includes a built-up or reinforced portion(40) formed at a rear edge thereof to provide for attachment and retention of a draw-string type plastic bag(11),
- wherein said plastic bag(11) has plural holes or apertures(15) formed therein,
- said plastic bag(11) having a first end for attaching to said chute(30), a draw string(12) on said first end and a second end which is permanently closed to retain the leaves and debris.
