Abstract
A readily portable apparatus for the size reduction of vegetable and cellulosic material is disclosed. A first shredding means having a plurality of knives is coaxially disposed with an impellar. After contacting the shredding knives the impeller directs the partially shredded material to a contacting screen or impediment which further reduces the size of the vegetable and cellulosic material. The contacting screen is pivotally movable to promote the flow of material to a discharge chute for collection. The apparatus includes means to convert the apparatus to a leaf blower and provides for attachment of a vacuum collection means. Novel safety features preventing access to moving portions of the apparatus are also disclosed and claimed.
