A forestry site preparation system is provided for removing woody material, including trees, stumps and slash from forest terrain. The system includes clearing means having a means attached thereto for fragmenting the woody material and directing the particulate masses produced by this fragmentation toward the clearing means. An auxiliary fragmenting means closely associated with the fragmenting means is also provided. By setting the distance between the fragmenting and auxiliary fragmenting means, respectively, particulate masses of a maximum, predetermined size can be produced. A tree-felling assembly extending outwardly from the housing to which the fragmenting means is mounted is employed in felling the standing trees by exerting a positive force on the tree, thereby causing felling to occur in a direction away from the system. If desired, the particulate masses can be collected and transferred to a remote storage area.
A forestry site preparation system adapted for use with an apparatus capable of transporting said system through woody terrain, comprising means for clearing woody material, including trees, tree stumps, and slash, for said woody terrain, said clearing means including means for fragmenting said woody material into particulate masses and said system also comprising at least one auxiliary fragmenting means for further fragmenting said particulate masses, thereby substantially controling the size of said particulate masses, said clearing means further including means for conveying said particulate masses toward said auxiliary fragmenting means.
