Abstract
An apparatus for holding a plurality of flexible cutting filaments having an angular cross-section for cutting grass and the like comprises a rotary member. The rotary member includes a hub for mounting the member to a drive shaft of a lawn mower or the like. The member includes a rim disposed around the hub. A disk secures the rim to the hub. The member includes at least a pair of passageways for securing at least one pair of flexible cutting filaments. The passageways are keyed to the cross-section of the cutting filaments and extend through the rim for permitting the filaments to be positioned within each respective passageway at a specific orientation. Each of the passageways extends through the rim at different elevations above the ground for permitting the cutting filaments to cut the grass at different heights.
