摘要 A cutting head for a lawn trimmer is provided and consists of a cylindrical housing block bolted to a lower portion of the lawn trimmer so that the housing block is rotatably mounted thereto. A flexible cord with a knot at center of the cord is placed within an opening of the housing block with ends of the cord extending outwardly through each of a pair of opposed holes at side of the housing block.
