<p>This invention is for an improved cutting assembly for a rotary mower, edger, trimmer or the like. It includes a body member arranged for rotation about an axis generally perpendicular with or normal to the cutting plane. It preferably includes one non-metallic cutting line attached to the body member at three alternate sites for rotation therewith in the cutting plane, although a pair of lines may be effective for present purposes under proper circumstances. More particularly, provision is made via metallic bearing surfaces for the reduction of friction between the cutting lines and portions of the apparatus and between adjacent portions of the cutting lines, and for higher speed and cutting efficiency.</p> |
