Abstract:
A brushcutter blade with an undulated peripheral cutting edge, wherein the edge alternates partly circular cutting sections, with partly arcuate, radially recessed cutting sections. Recessed cutting sections provide accelerated radial cutting and also additional axial shredding. Auxiliary axial segments are formed or deflected out of the blade body around a base line or juncture with the blade, at angles acute to the plane of the blade, and the openings through the blade created thereby, are radially outward of the juncture. The segments are configured to provide an inclined leading edge for each segment, that cuts a laterally extended path with the movement of the blade, and enhances both radial and axial shredding. A contrasting vivid color band on distal cutting sections optically merges into a distinctively visible cutting edge for obstacle avoidance and safety enhancement.
