ABSTRACT:
A cutting device is provided to replace a conventional lawnmower blade which offers improved safety, outstanding grass cutting ability, improved grass bagging suction, and a reduction in the strain on the engine. The device includes an elongated, downwardly curved rigid thermoplastic member having an upstanding airfoil at each distal end. Several elongated flexible tines extend outwardly away and downwardly from the member. The tips of these tines operate to effectively cut the grass while flexing for safety if an object is encountered, such as a rock or toe. The airfoils increase the suction within the mowing cavity to increase the grass bagging efficiency. The downwardly curved configuration presents the tips of the tines for grass cutting while reducing or eliminating the drag of the member on the grass.
