摘要： A cord-type mowing tool having a cutter body formed with at least one radially extending bore for receiving a cord serving as a grass cutting blade, and a clamping member fitted in the central bottom opening of the cutter body for forcing against the central portion of the cutter body an end portion of the cord inserted in the radially extending bore to hold the cord in place. The clamping member is threadably connected to the cutter body, so that by loosening and tightening the threadable connection it is possible to readily replace the old cord by a new cord of a predetermined length. The grass cutting tool is simple in construction, light in weight and reliable in performance.
