MTD Gator Mulcher™ Blades "to fit"

Gator Mulcher™ Blades: The angle of the Gator tooth 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. The clippings easily fall through the cut grass leaving a beautiful lawn.

MTD Fusion® Blades "to fit"

Fusion® Blades: Stay sharper, and hold their clean cutting edge longer; sharpen as easily as a standard blade, just not as often; the difference is in the blade, not on the blade; R50™ hardness throughout the blade. Spend less time sharpening. Spend more time mowing grass and making cash. Tests prove it. Fusion® edges wear 40% less than the edges on standard blades.
