Its length of 22 inches makes it perfect for medium to big lawn mowers. It also includes a five-point star center hole, making it compatible with most current lawn mowers.

Overall, it’s a tough blade created in the United States of America from high-quality steel. Once you’ve sharpened it yourself, you’ll be rewarded with unparalleled durability and cutting power. The blade may not be the sharpest straight out of the box, but if you have a metal filer, you can easily sharpen it to your liking.

The blade is extremely lightweight, allowing it to be used on lawn mowers with internal systems that allow you to modify the lift level of the blades. This adaptability is ideal for cutting your lawn at various seasons of the year while still being able to gather grass clippings from the machine so they don’t trash your yard.

Another significant plus is the low asking price, which makes this a fantastic replacement blade if your present blades are beginning to dull or have just broken.

This is a mulching blade from the same manufacturer as our last selection, and it’s designed to the same excellent standards we’ve come to expect from MaxPower. The blade is great for mulching grass that has just been cut and spitting it out the side of the lawn mower. It acts as an immediate fertilizer for your soil.

Its dimensions are 21 inches long by 14 inches broad, making it ideal for most medium-sized lawn mowers used by homeowners. It has a 5/8-inch center hole and is produced in the United States. Before ordering this mulching blade, be sure you measure the mount that your lawn mower presently uses to ensure that everything will fit.

To make things even better, it comes with a list of all the blades and lawn mower models that it can operate with, which can be found on the back of the primary label or included with the purchase. In addition to all of these benefits, it’s a very reasonable replacement blade, even less so than the last MaxPower option we looked at.

This mulching blade, on the other hand, is dark steel in color. While this has no effect on its function, it does make cleaning it a bit more harder, since identifying dirt or grassy debris on the blade is more difficult, especially in low light. Make careful to clean the blade in strong light to ensure that all dirt is removed.

However, most commercial and household lawn mower customers would be hard-pressed to find a more cheap mulching blade. Get a pair so you’ll always have a spare in case of an emergency.

Things We Enjoy:

  • Mulching blade at a low price
  • Effectively mulches grass
  • Fits a wide range of lawn mower models
  • The hole in the center is well-cut.

Things We Despise:

Check out this universal replacement blade if you have a lawn mower with a unique brand or model, or if you’re not sure whether the other two blades we evaluated will fit exactly. It’s designed to fit any lawn mowing equipment that can handle blades that are 20 inches long and 2.25 inches wide.

It does this by having six reduction washers that may be used to adjust the fit of the center cut hole, which is by default 1 inch in diameter. This is a bit too big for many current washing machines, but it will fit in a few older ones. If the main hole does not automatically fit your machine, just place one of the provided washers on its surface and it should fit.

3/8 of an inch, 7/8 of an inch, 9/16 of an inch, 5/8 of an inch, and 13/16 of an inch are the diameters of the washers. Most lawn mower manufacturers in the present day utilize them to cover all of the primary mount hole sizes. As a consequence, if you wish to share blades for various sized mowers, you may exchange this blade between other lawn mowing equipment.

The blade is a dark hue and is sharpened straight out of the box, however a little honing before use is always recommended. Cleaning the blade is a bit more difficult than cleaning a silver-colored blade, but overall, it’s a flexible replacement that should make getting a new blade for your specialized mower a lot easier.

It’s also reasonably priced and, like other MaxPower lawn mowers, is built in the United States. The looseness of the washers is one disadvantage to be aware of; you may want to double-check that the blade is fully fastened before spinning it up. The washers may shake or spin free, especially at first, wreaking havoc on the bottom of your lawn mower. You shouldn’t have any problems if you tighten them properly.

Things We Enjoy:

  • Six washers are included to adjust the fit size.
  • It’s built of tough, long-lasting steel.
  • Fits a large number of lawn mowers
  • It’s simple to replace the washers.

Things We Despise:

  • The washers might be a touch loose at times.

Replacement Blade for Toro 22″ Recycler Mower

Affiliate links / Images from Amazon Product Advertising API / Last update on 2022-02-20

This blade, which has two pairs of teeth on each end of its length, is ideal for mulching. It is 22 inches in length and is suitable for medium to big lawn mowers. Because of the teeth, it’s an excellent mulching tool that can easily cut through even the toughest weeds and transform them into excellent fertilizer for the rest of your yard.

The blade is manufactured of high-quality steel with a black paint finish that keeps it from corroding or sustaining damage as quickly as blades that aren’t coated. This makes it a bit more difficult to clean, but overall, it’s a long-lasting blade that’s an excellent alternative if you don’t want to buy new blades all the time.

This blade has three mounting holes to select from, so it should fit on most current lawn mowers without too much trouble. If you have the correct mower model, you may alter its height as well, allowing you to further personalize the performance of this blade.

It cuts through thicker or harder grass with reasonable sharpness, but it should be sharpened on a regular basis with your own metal file since the edges wear out rapidly. This is a disadvantage since blade sharpening maintenance isn’t required very often. However, we’re prepared to give it a pass since this blade is best suited for mulching tougher grass that fights back.

If you want something heavy-duty that can wrangle your yard into shape without any problem, pick out this mulching blade. It’s inexpensive and comes with free delivery.

Things We Enjoy:

  • Extremely long-lasting and durable
  • Even thicker grass may be mulched without trouble.
  • Is reasonably priced and includes free delivery.
  • On each end, there are two sets of teeth.

Things We Despise:

5. EGO Power+ AB2101 Lawn Mower Blade (21-Inch)

Affiliate links / Images from Amazon Product Advertising API / Last update on 2022-02-20

This high lift 21-inch lawn mower blade is ideal for lawn mowers that handle unmanageable yards and very thick grass. It’s an excellent option for lawn mowers with high horsepower or bigger machines that gather a lot of grass into heavy-duty bags. Indeed, this lawn mower blade was created particularly for lawn mowers that collect their clippings in a bag.

It has a factory sharpened steel blade that performs well no matter what kind of grass or weeds you’re cutting. It does need to be sharpened now and again, but it usually produces a really clean cut that may quickly clear up your yard’s overgrowth.

As a result, we believe it’s a perfect option for heavy-duty lawn mowers or professional mowers that must routinely take their equipment into untamed backyards.

It also has a slanting arc on one of its arms. As a consequence, this lawn mower blade catches grass clippings effectively and consistently tosses them into the bag. Lower-quality lawn mower blades have a tendency to drop grass trimmings under the mower’s belly, but this blade performs a fantastic job of not letting anything get away.

It has a circular mounting hole, but you can alter the size of the hole with several fitting washers to make it work with most current lawn mowers. However, be careful to measure your mount before making a purchase.

The only drawback is the somewhat high asking price, which for a single blade is a little on the high side. If you want something long-lasting and heavy-duty, it’s still a good buy, but keep in mind that this is primarily meant as a primary-use blade that should last a long time rather than a cheap replacement. To get the most bang for your money, take excellent care of it.

Things We Enjoy:

  • Steel of exceptional grade
  • Cutting is simple with sharp edges.
  • For grass trimmings, good collecting margins are essential.
  • Most lawn mowers are compatible.

Things We Despise:

  • Is a little on the costly side for a single blade

What to Look for in a Mower Blade for a Lawn Mower

Focus on these important considerations when purchasing a lawn mower blade to ensure that you get the best blade for your requirements.

Mulching vs. Lifting: Which is Better?

First and foremost, think about the sort of blade you want to buy. Lawn mower blades can either raise or cut grass, making them ideal for domestic usage or for swiftly removing grass. Mulching is possible with other blades, but they are unique and ideal for various reasons.

Lifting the blades of your lawn mower collects grass and funnels it into a bag at the rear of the machine for simple disposal.

Low Lift

Low lift lawn mower blades are perfect for cutting a standard back or front yard and are especially useful for smaller lawn mowers that have limited room. They’re especially useful for clipping grass in residential areas rather than wild weeds. Low lift blades also need less maintenance and are suitable for casual usage.

Low lift blades use less fuel and energy than other blades since they are lighter and spin at a slower speed.

Medium Elevation

Medium Elevation blades are larger in size and are ideal for cutting thicker grass and some thinner variants of weeds. Because of their versatility, you can use medium-lift lawn mower blades for both commercial or residential mowing jobs.

They are also among the simplest to locate due to their adaptability. Medium-lift lawn mower blades may be found at most places, both online and in person. They’re also great if you haven’t mowed your backyard in a while and don’t want to ruin your grass or the earth.

High Lift

High lift lawn mower blades are ideal for quickly shearing through large amounts of grass. They can remove a lot of grass and weeds considerably faster than other lawn mower blade types, and they can function for much longer since they are composed of more robust materials that can endure a lot of abuse.

On paper, they need more fuel or electricity to operate, but they may use less power altogether since they may finish a mowing task faster than the other two blade types. For commercial mowing, high lift lawn mower blades are ideal.


Mulching lawn mower blades (also known as “gator” blades) are effective for composting and finely trimming chopped grass. To function as a fertilizer, the grass is then scattered around your yard or outdoor area. If you want to utilize the same land or help it develop faster, this might be beneficial.

Length of the blade

The length of your lawn mower blades will, of course, affect how well they fit with your selected lawn mower and how much grass they can cut at once. Longer blades are better for bigger machines and can cut yards more rapidly, but they may be more difficult to utilize in confined spaces. Shorter blades are more maneuverable and ideal for smaller lawn mowers, but they take longer to cut the same area.

Overall, it’s a good idea to look for new lawn mower blades that are the same length as the ones that came with your mower when you first bought it. This assures that the blades are compatible with your machine, regardless of its make or model.

Type of Mount

Finally, think about the sort of mount that your lawn mower has. A mount is located at the bottom of every lawn mower and fits into a mounting hole drilled into the middle of all lawn mower blades. However, certain holes are made for specialized mounting.

Although both are star-shaped, there are two primary kinds of mounting. The most significant distinction between the two is that one has five points while the other has six. Examine them carefully to ensure that the blade you’ve picked is the correct shape for your mower’s installation.

In general, contemporary lawn mowers have five-point mounts, whereas older lawn mowers have six-point mounts.

When Should Your Lawn Mower Blade Be Replaced?

A: It depends on how well your yard looks after you’ve mowed it. Even if you simply ran your lawn mower over the area, your grass may seem ragged or harsh due to a faulty lawn mower blade. Replace any lawn mower blades that aren’t sharp enough to complete the job.

However, the duration of this impact varies from blade to blade and is dependent on how often you mow your grass. Most lawn mower blades may endure for months or even years before having to be changed. Depending on how often you mow, this amount will rise or fall.

Q: Is it possible to sharpen a lawn mower blade?

A: Without a doubt! To avoid injuring yourself, tip your lawn mower over and remove the spark plug if you don’t want to buy a new blade since your present one is still in mainly excellent shape. To avoid cutting yourself, remove your lawn mower blade using a socket wrench and wear gloves during the operation.

Sharpening the blades necessitates clamping it in a vice, which will keep the blade stable as you sharpen it. Take a metal file and run it from the inside to the outside of the blade’s edge. When you’ve finished, the cutting edge should be glossy and clean. As you complete this activity, be sure to keep an eye on the blade’s angle.

When you’re done, reinstall the blade and give it a try. Sharpening lawn mower blades does not need the services of a professional; do it yourself and save money!

Q: What is the best way to clean a lawn mower blade?

A: Carefully remove your lawn mower blade and clean out any grass, dirt, or debris with a garden hose. High-pressure hoses are good for cleaning since they remove more filth with less effort.

To take it a step further, dip a towel in vegetable oil and clean both sides of the blade. This will preserve the blade from rapidly deteriorating over time and will allow it to function smoothly for longer. It’ll also keep it from collecting as much dirt at first, however it’ll ultimately wear out and need to be replaced.

Cleaning should be done on a regular basis. Remember that a lawn mower is a tool; treat it well and it will look after your grass.
