Oregon 21-3/16" Gator Mulcher 3-in-1 MTD (5/8" Star)

High performance replacement mower blades from Oregon. Gator G3 mower blades (formerly known as Gator Mulcher 3-in-1 blades) come with a patented design that 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. The result is less bagging, less raking and quicker decomposition. These blades work extremely well in the fall for mulching leaves also. All Gator G3 blades are thru-hardened to a Rockwell C-scale hardness of 50 for optimum safety and durability, then individually straightened for a precision cut. Blades can be sharpened like any standard mower blade. Gator G3 blades actually work better in wet grass than standard blades. This is because the turbulence created by the tips of the teeth helps to keep the grass from clumping together. The updated G3 blades work even better in wet grass than the old style Gator Mulcher 3-in-1 blades because they move more air and discharge the clippings faster.
