Abstract
The present invention discloses an apparatus for cutting grass or vegetation and the like, which includes a rotary cutting member. The rotary cutting member includes a hub and a plurality of arms extending therefrom. Each arm includes a line holder for receiving a flexible cutting filament. The flexible cutting filament includes first and second cutting elements, and is positioned such that first element is positioned above and laterally offset from the second element. Each arm is shaped so as to form an air-foil. The air-foil creates a low pressure area above the blade which facilitates lifting the grass upward in the direction of the lawnmower blade.
