ABSTRACT:
The present invention discloses an apparatus for cutting grass and the like comprising a rotary cutting member. The rotary cutting member includes a hub and a plurality of arms extending therefrom. Each of the arms includes a line holder for receiving a flexible cutting filament. The flexible cutting filaments include first and second cutting elements. The flexible cutting filaments are prestressed so that the first cutting element intersects the second cutting element thereby forming a substantially V-shaped flexible cutting filament. Each of the arms includes an air foil positioned remote from the hub. The air foil creates a low pressure area above the blade which will facilitate lifting the grass upward in the direction of the lawnmover blade.
