摘要：A cutting attachment for u with a vegetation cutting device. The cutting attachment has a body with a generally planar coupling portion and a central axis of rotation. In one embodiment, the body further includes a conical central wall portion extending radially outwardly and in a first direction from the coupling portion and the axis and a circular outer wall portion adjoining the central wall portion and extending generally radially outwardly therefrom. The central wall portion defines a conically-shaped lf-cleaning inner cavity dispod symmetrically about the axis. The outer wall portion has a generally smooth outer surface which rves as a skid plate. An outer lf-cleaning cavity is formed by an outer surface of the central wall portion and an inner surface of the outer wall portion. A coupling asmbly, which can include an adapter having first and cond clamping elements, is carried by the coupling portion for coupling the body to the cutting device to cau rotation about the axis. A plurality of spaced apart radially extending cutting elements, in the form of cutting blades and/or cutting strings, are carried by the body. Cutting blades are provided with aerodynamic configurations, rrated edges, inner and outer cutting edges and arms for curing the blades to the cutting attachment which permit longitudinal movement of the cutting blade with respect to the cutting attachment. Cutting strings are provided with inner and
outer cutting portions, grooves for reducing fraying and a spiraled configuration.
