A system is provided for handling debris, such as twigs, leaves, grass cuttings, refuse and the like comprising a fan-shredding device including a vacuum nozzle, the nozzle being shut off from the fan suction when various units are mounted thereon, such as a hopper and a flexible extension hose. Also, a blower is provided by similarly mounting a cowl on the nozzle and a blower tube on the discharge chute of the fan-shredding device. Shredded debris is bagged in a bag mounted on the discharge chute. On bagging, the shredded debris is compacted by the fan blowing action on the small shredded particles.

A system for handling debris, such as leaves, twigs, refuse and the like, convertible for use as a blower or as a vacuum, comprising: a wheeled frame; a device mounted on said frame including an impeller housing having a vertical rear wall, a vertical front wall and a side wall therebetween having a cylindrical inner surface and a top discharge chute extending tangentially outwardly from said surface, an impeller having a circular disc vertical rear support and a hub extending axially forward from said support and two substantially radial blades extending longitudinally of and substantially diametrically outwardly from the hub, said hub being adapted for coupling to a rotatable stub shaft extending through said rear wall, said front wall being spaced forwardly of said impeller and having an inlet hole larger than and axially aligned with said hub, a vacuum nozzle connected to and extending forwardly and downwardly from said front wall past said front wall and said frontwall inlet hole and having a front inlet hole in axial alignment with said front wall inlet hole; an intake device optionally and removably mounted on said vacuum nozzle over said front inlet hole to allow for flow through said front wall inlet hole; an exhaust device optionally and removably mounted on said discharge chute to allow exhaust flow therethrough; three shredding bars longitudinally connected to the housing inner surface, each having a leading shredding elongated corner presenting a radial face, an edge and a peripheral face for debris shredding, one of the bars being positioned at the tangential connection of the chute to the inner surface and the other two bars being positioned at 120°locations therefrom so that only one blade at a time passes a shredding bar; said blades each having an outer longitudinal peripheral edge and a forwardly flaring radial flange extending in the direction of rotation for coacting with said inner surface and shredding bars to produce an air and debris flow through the front wall inlet hole and the housing and the discharge chute and to shred the debris while in the housing.
