Regardless of the size and type of lawn mower you have, the durability and design of the blades underneath the deck impacts the effectiveness of your machine more than you might think. Small rocks, roots, and wood chips can dent and bend those blades over time, which reduces their efficiency and can actually put more stress on the mower engine. These worn-out blades can also rip and tear your grass instead of cutting it cleanly—resulting in a discolored and ragged-looking yard.
We recommend that you replace your lawn mower blades once a year to make sure your mower is working efficiently, so we’ve rounded up the best lawn mower blades on the market to make maintenance as easy as possible.
If you're considering a new mower this year, check out our picks for the best lawn mowers, the best riding mowers, and the best zero-turn mowers.
The Best Lawn Mower Blades
What to Consider
The most important factor to consider is compatibility with your lawn mower. Luckily, mower manufacturers have made things easy by placing the serial number in a visible, easy-to-find area, usually on top of the unit towards the back.
As long as the mower’s serial number matches the same one on the blade product listing, it should fit just fine. Don’t skip this step—you can easily end up with a blade that doesn’t fit correctly if you do. Many of the blades we recommend, like our best overall pick from 8Ten, are compatible with several models from multiple popular mower brands.
The type of blade is another important factor to think about. Some mowers only work with one type of blade, while others are compatible with different lift designs.
These varying designs include mulching options that are ideal for powering through thicker, heavy-duty lawns; high-lift blades for efficiently throwing clippings a long distance; and low-lift models that create minimal noise and dust.
Keep in mind that most lawn mower blades are already sharpened, but may not appear to be since many use a coating to protect them while shipping. This coating naturally comes off while you mow, so unless the directions specifically tell you to do so, you don’t need to sharpen lawn mower blades.
Lawn mower blades are not as sharp as you might expect and don’t have a razor-thin edge as it would easily bend and dull from the roots, sticks, and rocks.
How We Selected
I spent years as part of the landscaping team at a large state park, operating, maintaining, and repairing lawn mowers—a job that required a lot of blade replacements. Since I used both riding lawn mowers and walk-behind mowers on the job, this gave me experience with different types of blades and manufacturers, as well as the factors that go into installation and overall operation.
We curated a list of basic options that fit mowers popular for residential use to make sure our recommendations fit your machine. We only recommend options from reliable brands we’ve grown to trust over time, like 8Ten and Maxpower.
