Take your landscaping and yard work to the next level with Makita Cordless Outdoor Power Equipment. The 21-inch Lawn Mower Blade is ideal for use with Makita 21-inch lawn mowers including models XML10 and the XML11 (sold separately). The 3-in-1 mower blade can be used for mulching, bagging, or side discharge. The cutting edge of the blade tilts forward when properly installed which prevents double-cutting and improves run time. It is engineered to cut cleanly and create fine clippings to help promote lawn health. For improved convenience, it installs quickly and easily using only one bolt.
