ABSTRACT:
A rotary filament assembly is provided wherein a plurality of resilient monofilaments are attached to a rotary member such that free portions of the resilient monofilaments extend substantially vertically when the rotary member is at rest and such that upon rotation of the rotary member at a predetermined speed, the free portions sever vegetation, such severance serving purposes of mulching and/or cutting and trimming. In one embodiment (10) used in a power lawn mower (29), the rotary filament assembly can cut and/or mulch vegetation and has resilient monofilaments (14) mounted to a blade (12) such that their free portions (24) extend substantially upwardly when the blade (12) is at rest. In another embodiment (110) used in a hand-held power trimmer, resilient monofilaments (128, 128', 130, 130', 132, 132') are selectively mounted on a solid disk (112) such that their free portions (130a) extend substantially downwardly when the solid disk is at rest.
