ABSTRACT:
A filament employing lawnmower blade apparatus includes a support disc which includes a central transverse lawnmower connection channel and a plurality of peripheral transverse fastener reception channels. A plurality of filament reception fasteners are provided each of which includes a fastener head, a filament reception channel located adjacent to the fastener head, a threaded shaft located adjacent to the fastener head, and a threaded nut screwed onto the shaft. A plurality of filaments are received in the respective filament reception channels of the filament reception fasteners. For each of the filament reception fasteners, the fastener head and the shaft are arrayed along a fastener longitudinal axis, and the filament reception channel extends perpendicular to the fastener longitudinal axis. Washers are located on the shafts of the filament reception fasteners between the nuts and the support disc. The filament reception channel includes exterior walls which are arrayed in a polygonal pattern. The fastener reception channel is also in a form of a polygonal pattern. The polygonal pattern of the exterior walls of each of the filament reception channels is a complementary pattern to the polygonal pattern of the fastener reception channels. The polygonal pattern of the exterior walls of the filament reception channel and the polygonal pattern of the fastener reception channel are in forms of a four-sided square.
