G6 blades are 1/4 inch thick.Here are several reasons why I think the "G6" Gator Blade is the best blade for your mower.1 Gator blades are designed to recirculate the grass clipping into the cutting path resulting in finer clippings for quicker decomposition. This decomposition adds nutrients back into the soil quicker and is less likely to develop diseases that thicker clippings may develop.2 Unlike a mulching kit, gator blades still discharge out the side. This has several benefits. With a mulching kit it is recommended that the operator only cut off a 1/3 of the grass at a time. Crowding the mulching kit can leave clumps of grass lay behind because the mulching kit cannot handle a large amount of material. Since the Gator blade disperses clippings out the side, it had handle thicker and heavier grass.3 The Gator blade is wider and in some cases thicker than the standard blade. This results in a stronger, longer lasting blade.4 The G6 Gator blades have a longer cutting edge than most standard blades. This also aids in finer clippings and superior cut.5 The cutting edge of the Gator blade has a hard surfaced treatment Oregon refers to as Fusion. The process fuses tungsten carbide into the cutting edge resulting in a longer lasting cutting edge. 6 You get all this for a price that is usually much lower than the OEM replacement blade!We strive to provide the highest quality of service found on ebay.
