发明名称 Rotary cutting assembly
摘要 An improved cutting assembly for rotary lawn mowers, edgers, trimmers or the like, including a body member arranged for rotating about an axis normal with the cutting plane. At least two cutting lines are attached to the body member on a compound spool for rotation therewith in the cutting plane. The invention includes means for detachably securing the lines to the body member and for storing a supply of the line on the spool 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.
