Abstract
A lawnmower blade includes an elongated flat bar having a central aperture for attachment of the flat bar to a rotary drive shaft for rotation of the blade in a predetermined direction in concert with rotation of the rotary drive shaft. The flat bar has a pair of opposite portions, extending in opposite directions from the aperture. A pair of first cutting edges are defined along outer sections of leading sides of the opposite portions of the flat bar and extend substantially perpendicular to the tangential direction of the path of rotation of the blade. A pair of second cutting edges are defined along outer ends of opposite portions of the flat bar and extend angularly outwardly from the outer leading side cutting edges to the outer trailing sides of the flat bar relative to the direction of rotation of the blade. The pair of straight outer leading side cutting edges also can have a plurality of crescent-shaped serrations or sawtooth-shaped serrations formed therein.
