The 8 Best Lawn Mower Blades 2022

Despite their sturdy construction and sturdy feel, your lawn mower blade can take some serious knocks while mowing your lawn. No matter how hard you try to avoid them, rocks, roots and wood chips can dent and bend your mower blades, and cutting millions of blades of grass constantly dulls the edge. Not only does a worn blade put more strain on your mower’s motor, it also affects the appearance of the lawn itself, resulting in discolored and ragged grass. It is recommended that you replace your blades once a year to ensure that your mower is operating as efficiently as possible. We’ve rounded up the best lawnmower blades on the market to help you out.

The best lawn mower blades

What to consider

The first thing to consider when choosing a lawn mower blade is whether or not it will fit your existing lawn mower. Luckily, this is a fairly simple process, and mower manufacturers have made it easy by placing the serial number in a visible, easy-to-find area, usually on the top of the unit towards the rear . As long as the mower’s serial number matches the same number on the blade retailer’s listing, you should be fine. If you skip this step, you can easily end up with a blade that doesn’t fit properly or is the wrong length.

The type of blade is another factor to consider. Your mower may only accept a specific type of blade, but others allow you to be a bit more flexible and are compatible with different lift designs. These can include mulching options that are ideal for traversing thicker, tougher lawns, high-lift blades for effectively throwing clippings a long distance, and low-lift models that create minimal noise and dust.

Keep in mind that most lawnmower blades are already sharpened, but may not appear to be since many use a coating to protect them in shipping. This coating will naturally peel off as you mow, so unless you’re specifically told to do so, you probably don’t need to sharpen them. Lawnmower blades are also not as sharp as you might imagine and do not have a razor-thin edge, which would easily bend and become dull from roots, sticks and rocks that you will inevitably crush as you go.

How we selected

I spent years on the landscaping crew of a large state park, operating, maintaining, and repairing lawn mowers, a job that required a significant number of blade replacements. Since the park used both ride-on and walk-behind mowers, it gave me experience with different types of blades and manufacturers, as well as the factors that go into installation and general operation.

Since residential users will most likely be looking for blades for a variety of mowers, I’ve done my best to curate a basic list of options that should either fit your mower or at least send you into the right direction in terms of reliable and popular brands. , such as 8TEN and Maxpower.
