ABSTRACT:
A rotary lawnmower blade that includes cutting edges on removable cartridges which can be replaced without the use of tools. The blade is hollow in design with air inlets that pick up high volumes of air as the blade rotates, compress the air and discharge it at an increased velocity to aid in discharging the grass clippings and other debris. The blade also is designed to increase the suction action of the blade as it rotates in order to make the grass more erect and also pick up the grass clippings more effectively. Also included in the design is an unique method of attaching the blade to the engine drive shaft so as to minimize damage if the blade strikes a solid object.
