From the Manufacturer
The Gator Mulcher 3-N-1 blade unique design has revolutionized the way blades mulch grass clippings. The angle of the Gator teeth redirects the air flow to keep the clipping directly in front of the cutting edge. The longer the clippings remain in front of the cutting edge, the finer the size of the clipping. These 3-N-1 blades can be used for mulching, bagging, or side discharge mowing.
