An improved cutting assembly for rotary lawn mowers, edgers, or the like, including a body member arranged for rotating about an axis normal with the cutting plane. At least one cutting line is attached to the body member for rotation therewith in the cutting plane. The line is characterized by having a working length to diameter ratio and a material composition to render the line substantially limp and nonself-supporting in the static condition. Certain embodiments of the invention may include means for detachably securing the lines to the body member and for storing a supply of the line on the body member so that the line may be paid out as the working portions of the line become shortened through wear. The cutting lines are preferably nonmetallic so as to reduce the hazardous condition which would otherwise be present for the operator and still provide an apparatus which will cut with great efficiency and safety. |
