Abstract:
A flexible rotary cutting device useful for attaching to a rotary drive configured to trim vegetation, particularly a lawn mower. The flexible rotary cutting device includes a cutting head, an attachment mechanism, at least one cutting-filament retention mechanisms, and at least one cutting-filament. At least one cutting-filament may be releasably attached to the at least one cutting-filament retention mechanism. The at least one cutting-filament may be configured to sever vegetation as the cutting head is rotated, and may be positioned such that it is passed through the at least one filament-aperture, and between the first-filament engaging pawl and the second-filament engaging pawl, in such a way that the at least one cutting-filament is engaged and anchored by the first-plurality of teeth and the second-plurality of teeth, and extends radially from the outer flange of the cutting head.

Claim (Index 19):
A method of trimming vegetation, the method comprising the steps of:\n providing a cutting device attachable to a rotary drive configured to trim vegetation, the cutting device comprising a cutting head including a disk, an outer flange affixed to the disk defining a cylindrical inner volume, a cover affixed to the outer flange concentric to the disk, and a rotational axis passing through the center of the disk, an attachment mechanism affixed to the cutting head for releasably attaching the cutting head to the rotary drive, at least one cutting-filament retention mechanism including a first-fulcrum cylinder having a first-fulcrum axis affixed to the cutting head, the first-fulcrum axis being parallel but not concentric to the rotational axis, a second-fulcrum cylinder having a second-fulcrum axis affixed to the cutting head, the second-fulcrum axis being parallel but not concentric to the rotational axis, a first-filament engaging pawl pivotably engaging the first cylinder having a first-plurality of teeth, a second-filament engaging pawl pivotably engaging the second cylinder having a second-plurality of teeth, the second-filament engaging pawl mirroring the first-filament engaging pawl, at least one filament-aperture disposed within the outer flange of the cutting head, and at least one cutting-filament releasably attached to the at least one cutting-filament retention mechanism, the at least one cutting-filament being configured to sever vegetation as the cutting head is rotated, the at least one cutting-filament being passed through the at least one filament-aperture, and between the first-filament engaging pawl and the second-filament engaging pawl, such that the at least one cutting-filament is engaged and anchored by the first-plurality of teeth and the second-plurality of teeth, such that the at least one cutting-filament extends radially from the outer flange of the cutting head; coupling the attachment mechanism to the rotary drive; inserting the at least one cutting-filament into the at least one cutting-filament retention mechanism; rotating the rotary drive in order to rotate the cutting device in tandem with the rotary drive; and severing vegetation with the at least one cutting-filament as the at least one cutting-filament makes contact with vegetation.
