Maintain a Healthier Lawn With New Lawn Mower Blades

Brand new lawn mower blades give your grass a faster, healthier cut. If your grass looks torn rather than cleanly cut after mowing the lawn, it's time to replace your blades. 


Different mowers vary in deck width, so whether you handle a push mower or riding mower, you'll need to measure the deck width to determine the correct blade size for your machine. See our guide — How to Maintain a Push Mower — for more lawn mower blade replacement tips. 


When buying new blades, it's also useful to consider specific grass-cutting features. Specialty blade types help you tackle the task for your situation, whether that's regular grass, heavy leaf foliage or a sandy subsurface. For example, the star-shaped holes in mulching blades chip up grass into smaller pieces to be returned to the lawn for added nutrients. Many Craftsman lawn mower blades are made for mulching, bagging and more.
