Patent ID: 7171798

Claim:
A rotary brush cutting and shredding blade for mounting to driven shaft of motorized brush cutter, comprising: a circular disk member constituting bilateral planes and having both top and bottom sides circumscribed by a peripheral border, with serrated cutting elements disposed on said peripheral border in a direction of rotation of said disk member for cutting, and a center aperture for mounting of said disk member to said driven shaft with the top side adapted to face toward the upper continuous extend of said driven shaft and the bottom side adapted to face away from the lower terminus of said driven shaft, for urging circular movement of said disk member in the disposed direction of rotation; at least one auxiliary cutting means extending below said disk when mounted to said shaft and having an unsevered angular juncture with the disk member and having three sides severed, and said auxiliary cutting means located radially outward of said central aperture position and radially inward of said peripheral border, said auxiliary cutting means deflected substantially out of the plane of said bottom side of said planar disk member; each said auxiliary cutting means including structures having predetermined surface configurations, whereby adherence of debris is impeded and shedding of debris is urged by centrifugal forces and manufacturing is simplified and economized, and said unsevered angular junctures oriented lengthwise into the direction of rotation, whereby said auxiliary cutting means are made impact resistant and strengthened, and whereby said auxiliary cutting means provide both axial and radial cutting and shredding capabilities.
