Abstract
A trimmer head for supporting replaceable flexible cutting elements used in trimming grass and weeds is equipped with several arbors to facilitate operative attachment to existing power tools. A head is positioned on the chuck of a selected arbor and includes grooves and abutments to receive and frictionally engage the medial portions of the flexible cutters, whose feed ends extend radially beyond the head. A circular shield is threaded on the arbor and tightened against the head. The circular shield includes a clamping plate which engages and clamps the medial portions of the flexible cutters against the head in use.
