Abstract
A tree cutting attachment for a skid loader or other types of self-propelled work vehicles to be used at construction and landscaping sites. The device is used to cut down brush and trees of up to 8-10 inches in diameter. The tree cutting attachment is made up of a motor driven rotor assembly which is journaled within the frame of the attachment. The rotor assembly comprises a cage-like mounting system having pockets in which tempered steel blades, approximately 6 inches in width are bolted in a side-by-side relation. Two rows of blades are mounted 180 degrees apart proximate the periphery of a rotor comprised of a series of parallel, generally circular plates that are welded to longitudinally extending rods. The knife blade elements are bolted to the blade holders with the non-sharpened end of the blade elements abutting a flat steel bar that forms part of the cage.
