| 摘要 | A cutting attachment rotary edgers having a planar base and a plurality of cutting fins or evacuating blades that extend outward from an outboard side of the base. A plurality of teeth are formed along a peripheral edge of the base and are defined in part by leading edges which face a direction of rotation. The cutting fins extend outwardly from the base at an acute angle so that distal ends thereof are angled in a direction opposite of the direction of rotation. The cutting fins are also spaced apart from the leading edges of the teeth of the base. The cutting fins are further attached along bases thereof at acute angles with respect to the leading edges of the teeth of the base so that radially outermost ends of the bases of the cutting fins are spaced further from the leading edges of the teeth than inner most ends of the bases of the cutting fins. | ||||||
