The unique blade helps chop grass clippings finer than with standard blades. This can lead to bagging up to 50% more grass and less visible clippings when mulching. Sharp-edged blades cut grass cleanly and make their way through grass more efficiently, reducing overall mowing time and effort. Xtreme blades outlast standard blades in sandy conditions. Ideal for finely cutting grass clippings and redistributing them back into your lawn, providing essential nutrients. Mulching saves time by replacing the need for raking, bagging and hauling away leaves and clippings.
