Our new mulching kit is as environmentally responsible as it is user friendly. Using our mulching blade and insert will result in shorter grass clippings, which serve as a natural fertilizer for your lawn. Our kit is quick and easy to install and minimizes the amount of clippings that need to be landfilled. You can also collect and remove the grass clippings from your lawn simply by switching out the mulching insert for the included grass catcher. The mulching kits are available for the RMA 370 and RMA 410 C STIHL Lithium-Ion mowers.
