Lawn Mower Blades: The Ultimate Guide (Types, Measuring, and )

Purchasing replacement blades for your lawn mower is a relatively easy task if you know your lawn mower blade’s part number. If you have your lawn mower’s model and serial number, referencing that mower’s model and serial number parts diagram is another fool-proof way to purchase the correct blade.

But, what if you don’t have any of these part numbers to reference? How do you determine which blades will fit your mower?

By the time you are finished reading our Ultimate Guide to Lawn Mower Blades article, you should have all the info you need to purchase a blade that will work perfectly with your lawn mower.

How to measure lawn mower blades

We’ll get into the various types of lawn mower blades further into the article (skip to view types of lawn mower blades). First, we will walk you through measuring the blade on your lawn mower to determine which size blade you need.

Measure mower blades diagonally

The most common mistake we see when people are attempting to measure their lawn mower blade is measuring straight across the blade. This is going to give you an inaccurate measurement!

To properly measure a lawn mower blade, measure the blade diagonally.

Center hole diameter

The next measurement you will need is the diameter of the center hole of your lawn mower blade.

If your mower blade has 3 holes, make sure you are measuring the center hole!

To measure the diameter, measure straight across.

If your mower blade does not have a circle for the center hole, you will need to determine what the shape in referred to. on mower blades without circle-shaped holes in just a second.

If your mower blade has outside holes

If you notice 2 holes on either side of the center hole in your lawn mower blade, you will also need to take some measurements here.

Many push lawn mowers and some other types of mowers utilize these outer holes to ensure the blades do not hit each other while in use. Many commercial lawn mowers use 2 or 3 blades, not just 1 blade.

A perfect example of this is the Exmark Commercial 30. This is an oversized 30 wide commercial push mower that utilizes the center holes to ensure each blade is mounted in the correct position.

Once again, you will want to measure the diameter of these holes.

You will also need to measure the distance between the center of these 2 outside holes. This measurement is referred to as center to center.

Lawn mower blade center hole types

Most lawn mower blades have circles as the center hole shape. If your blade does not, here is a quick reference of other possible mower blade center hole types.

Less common but not pictured center hole types include a square and a 7-point star center hole.

Measuring your mower blades width

The width of a lawn mower blade is usually not relevant to the fitment of the blade but we wanted to make sure you knew where to measure if this is applicable to your mower.

To accurately measure the width, make sure you are measuring straight across and measuring at the widest section of your blade.

Right-hand cut vs left-hand cut blades

Believe it or not, the cutting edge is not on the same side for all lawn mower blades.

Right-hand cut lawn mower blades are overwhelmingly the most common type.

Left-hand cut blades can be found on some mower’s manufactured by Kubota, Woods, Walker, and others.

Lawn Mower Blade Thickness

It is recommended to stick with the specs of the blade that came stock on your lawn mower. If for whatever reason you cannot determine the OEM blade part number, don’t stress about the thickness of the blade. It is not a huge deal, although using a blade that is too thick could lower the RPMs to a point where cut quality is lost.

As you might expect, blade thickness is measured by measuring the top of the blade to the bottom.

If you are bending a lot of blades, you may want to purchase a thicker lawn mower blade or just stop hitting rocks! Believe me, I’ve had 100 employees in my lawn care business over the years and completely understand if you are not sure if your employees are looking at what they are cutting as they are working!

Types of lawn mower blades

Now that you understand how to measure lawn mower blades properly and the various types of center holes you may find, let’s take a look at the different types of lawn mower blades and when you may want to consider each type.

We should mention you may see standard blade in the description of some lawn mower blades. This is basically the middle ground between high lift and low lift lawn mower blades. It is pretty suitable for any type of cutting.

High lift lawn mower blades

High lift lawn mower blades create a lot of lift due to the exaggerated fin on the non-cutting edge side of the blade.

When to use high lift lawn mower blades:

  • When you are cutting tall grass ( Grass over 3 tall )
  • When you are cutting flimsy grass such as turf-type tall fescue

When not to use high lift lawn mower blades:

Low lift lawn mower blades

Low lift lawn mower blades c reate little lift due to the exaggerated fin on the non-cutting edge side of the blade.

When to use low lift lawn mower blades:

  • When you are cutting short grass (Grass under 3 tall)
  • When you are cutting rigid grass such as Bermudagrass
  • In sandy soil conditions (see flat blades too)

When not to use low lift lawn mower blades:

Gator blades

Gator blades are also referred to as 3-in-1. Gator blades are often used by professional mowing companies in the fall to shred leaves as they mow. S ome companies run gator blades all year long.

Gator blades also shred longer grass blades before being discharged from the mower’s deck. Gator blades do create some lift.

When to use gator blades:

When not to use gator blades:

Mulching blades

Mulching blades mulch the grass clippings to allow for returning the grass clippings to the soil as natural nutrients.

It is important to note, you can certainly discharge the clippings from the mower’s deck back into the lawn without mulching blades as long as you are cutting your grass on a frequent enough basis.

When to use mulching blades:

  • When you are not discharging the clippings or bagging
  • When you are following the 1/3 rule (only remove 1/3 or less of the grass blade each time you mow)

When not to use mulching blades:

Flat lawn mower blades

Flat lawn mower blades create zero lift due to the blade being completely flat.

When to use flat lawn mower blades:

When not to use flat lawn mower blades:

  • Most of the time! Only use flat lawn mower blades when in extremely sandy soil conditions and cutting a rigid grass type

Self-sharpening lawn mower blades

To ensure this article covers all the bases, we wanted to include a new option when it comes to lawn mower blades.

Self-sharpening blades use patented technology to literally sharpen themselves as you mow. The early adopters seem to agree that these blades do in fact sharpen themselves.

Of course, these blades come with a hefty price tag as far as lawn mower blades are concerned. It will be for you to determine if they are worth the investment.

When to sharpen lawn mower blades

Factors such as how much use, what type of grass you are cutting, the length of grass you are cutting, soil conditions, and other factors will determine how often you will need to sharpen your lawn mower blades.

How to Sharpen and Balance a Lawnmower Blade

After finishing this article, check out our guide on sharpening lawn mower blades.

The best way to determine when you need to sharpen your lawn mower blades is by simply looking at the cut quality. This refers to the sharpness of the cut you are getting out of your blades. In the picture above you can clearly see the blades on the lawn mower that cut this grass need to be sharpened as they are tearing the grass instead of cutting it.

How to tell if a mower blade has been sharpened too many times

If you read the manuals, most lawn mower blade manufacturers recommend replacing the blades when there is 1/2 left between the cutting edge and the fin, sail, or lift. The fin, sail, or lift is referring to the part of the blade that is angled up.

If you continue to mow with less than 1/2 of material left, you are putting yourself and others in danger as there is a great possibility this blade could fail and send a piece of the blade flying from your mower. Please take this recommendation seriously!

Even if no one is hurt if this occurs, you very well could be on the hook for property damage costs.

When to replace lawn mower blades

At some point, lawn mower blades can no longer be sharpened and will need to be replaced.

You may need to replace your lawn mower blades because you have sharpened them too many times and have removed too much material from the blade.

Other reasons you may need to replace your lawn mower blades are much more obvious.

For example, if you bend your lawn mower blade, it should be replaced. Please do not attempt to bend it back to being straight once again. The integrity of the blade was lost as soon as it was bent.

Other reasons to replace your lawn mower blades include large chunks missing due to hitting an obstacle or hairline fractures. You should always inspect your lawn mower blades when sharpening or if you know you just hit an object you shouldn’t have!

OEM vs Universal Lawn Mower Blades

Something worth noting about lawn mower blades is that you do not have to stick with the OEM blades that came with your lawn mower!

Some stock blades simply do not provide a great cut quality. The 2 most important factors when purchasing aftermarket blades is that you purchase blades with the same length and center hole diameter. If your blade has the additional outer holes, you need to account for these specs as well.

Above is an example of a universal replacement blade that has an elongated hole instead of a circle. You will often see this on universal blades that account for outer holes because they want the blade to fit as many makes and models of mowers as possible.

Lawn Mower Blade Conclusion

To wrap this up, let’s just summarize the most important information we covered.

The 2 most important things to note when purchasing lawn mower blades is the length of the blade and the center hole diameter.

Make sure you purchase a blade with the appropriate outer holes as well if your mower requires them.

Use high lift blades if you are mowing cool-season grasses.

Use low lift blades if you are mowing warm-season grasses.

Try gator blades if you are mowing long grass or would like to shred leaves as you mow.

Mulching blades should only be used with a mulching lawn mower or a lawn mower with a mulching kit installed.

At the start of growing season, part of the necessary prep every homeowner with hopes of a greener yard tacks (or should tack) onto the to-do list involves the cleaning and sharpening of lawn mower blades. If the blades are left dull, each afternoon spent mowing only rips and chews the grass. Coarsely cut grass doesn’t just look bad; it’s also more vulnerable to pests, disease, and drought. Read on for our step-by-step guide on how to care for your largest landscaping tool, and you’ll reap the benefits of a clean cut all season long.

Types of Mower Blades You Can Sharpen

If you own a walk-behind or ride-on mower, then you can remove and sharpen the blade yourself. Both types have a mowing deck that’s equipped with either one or two blades that spin horizontally around a vertical spindle. Remove each blade by loosening a single nut on the spindle. If you happen to own an old-fashioned reel mower, which uses multiple blades mounted to a cylinder, then you’ll need to take it to a lawn mower repair shop to have the blades sharpened.

How To Tell If Your Lawn Mower Blade Needs To Be Sharpened

How often to sharpen lawn mower blades can vary based on use and other factors, but your lawn will tell you if your mower blade is in need of a good sharpening. All you need to do is look for a few telltale signs of a poor cut.

  • Ragged cut: A sharp mower blade should slice cleanly through the grass. If it’s leaving a ragged edge, then the blade is tearing grass instead of cutting it.
  • Uncut grass: Look carefully at your lawn after you mow it. If there are sections that appear to be pushed down instead of actually cut, then your mower blade is too dull.
  • Uneven height: The grass blades should be at consistent height after you mow the yard. If they’re not, then the mower blade isn’t sharp enough to cut cleanly through the grass.
  • Nicked blade: In addition to examining your lawn, you should assess the blade itself. If there are noticeable nicks and dents on the blade’s edge, then it needs to be sharpened.

How to Sharpen Lawn Mower Blades in Less Than an Hour

The type of lawn mower blade sharpener you have in your shed or garage will dictate the best way to sharpen a mower blade. Read on to learn about how to handle this lawn-mower maintenance job using a file, power drill, or bench grinder.

Step 1: Disconnect the spark plug (on a gas mower) or battery (on an electric mower).

This is the most important step in the entire process. Gas mowers start by using centrifugal force, which the user creates by pulling the starter cord. Though very unlikely, it is possible to create that same force by turning the blade. Eliminate any chance of the engine starting by disconnecting the spark plug, which is found on the front of the engine.Those with an electric mower should make sure to either unplug it from its power source or remove the battery if it’s cordless.

Step 2: Remove the blade.

Flip the mower over, so you can access the blade. Holding one side of the blade to keep it from moving, loosen the blade’s mounting nut using your socket wrench. If the nut is on tight or you don’t feel comfortable holding the blade, use a piece of scrap lumber to hold the blade in place so you can loosen the nut.

Step 3: Clean the blade with a metal scraper.

Clean the blade with a scraper and assess its condition. If rocks, branches, and other debris have inflicted deep nicks, you’ll want to replace it. Otherwise, gather the tools you need to sharpen it manually or mechanically.

Step 4: Sharpen the lawn mower blade.

At this point, you have a few options for how to proceed with sharpening, depending on the tools you have at hand.

  • How to sharpen lawn mower blades with a file: Clamp the blade horizontally in a vise and run a bastard-cut mill file along the cutting edge, using a one-way down stroke. Follow the existing angle (usually 45 degrees, but you can refer to your owner’s manual for the ideal angle) until the blade has the sharpness of a butter knife. Aim to remove an equal amount of metal from the cutting edge of both ends of the blade. Counting strokes may help you keep track.
  • How to sharpen lawn mower blades with a power drill: A faster technique involves a power drill with a sharpening stone attachment. Clamp the blade—cutting side up—in a vise. Secure the sharpening stone in the drill; the stone’s plastic guide should rest against the rear of the blade to ensure the proper cutting angle. Put on safety glasses, turn on the drill, and move the stone from the center of the blade to the tip.
  • How to sharpen lawn mower blades with a grinder: The fastest way to sharpen the blade is with a bench grinder. With this method, you’ll need to be careful not to oversharpen the blade or remove too much metal. Oversharpening creates a thin edge, which is easy to damage, and removing too much metal shortens the life of the blade. Hold the blade perpendicular to the rotating wheel as you move it along the cutting edge at the angle of the existing bevel. This throws sparks, so be sure to wear safety glasses. If the blade gets too hot, dip it in a bucket of water to cool it.

Step 5: Check the blade’s balance.

Check the blade’s balance before remounting it, because a lopsided blade will wobble and overtax the mower’s engine. Set a blade balancer on a flat surface and rest the blade on the balancer using the center hole. If the blade dips, use the file, sharpening stone, or grinder to remove metal from the back edge—not the cutting edge—of the heavier side toward the end of the blade.

You can also check the balance by hanging the blade on a wall from a nail through its center hole. If the blade tilts to one side, remove material from that side.

Step 6: Reinstall the blade in the lawn mower.

Reinstall the blade to the spindle under the mower using the mounting nut. Tighten the nut with a socket wrench while holding the blade with one hand. Flip the mower over and reconnect the spark-plug wire or power source, and then get to work!

Final Thoughts

If your lawn mower isn’t cutting it, then it’s probably time to give that blade a good sharpening. This process isn’t difficult if you have the right tools for the job and follow the above instructions. That said, if mower blade sharpening isn’t something you have the tools or time to do yourself, you can have a local lawn mower repair shop sharpen your blade for you for about 15 to 20. If you examine the blade and determine that it’s too worn out or damaged to be sharpened, then you’ll need to purchase a new one that’s compatible with your mower brand and model for about 20 to 25.

The 7 Best Lawn Mower Blades 2023: Reviews and Buying Guide

A good lawnmower is characterized by two things. It’s motor power and its cutting ability. The blade of a lawnmower decides the quality and the length of trim you are going to get.

The best part about a blade in a lawnmower is that it can compensate for the motor power of the machine with its sharp edge. This means that you can have a better cut with a certain blade of length and sharpness even if your motor does not help you increase the speed of the cut.

But how do you pick such a blade? Well it all depends on three major factors

  • Length of the Blade: Obviously, the first thing that you are going to check is the length of the blade. Now there is no rule of thumb but please keep in mind that longer does not mean better. It has to fit within your lawnmower model. Most blades fall within the sizes of about 16.75 inches and 22 inches long. Most mowers can facilitate blades as long as 21 inches or 22 inches too. Pick based on the model.
  • Build Material : The build material of the blade perfectly is a choice you can make irrespective of the model of the mower. Lower metal can help you cut costs but not the grass. Please keep in mind that a blade to your lawnmower is more of a care investment and can influence the life of the mower itself. So strong stainless steel is mostly the best choice. Also, look at the paint job done on the blade so that it doesn’t end up getting rusted.
  • Deck Size: Finally, you should also take into consideration the deck size of the blade. Most of the push mowers have a deck size of the range 16 to 30 inches. Riding mowers have higher sizes of the deck as well.

Apart from these three factors, there are a bunch of more factors that you might want to check out. We have included all of them in the Buying Guide section of the article. Be sure to check them out as well.

Now let’s go and review the list of the best lawn mower blades you can buy.

Buying guide: How To Choose The Best Lawn Mower Blade?

Given that a lawnmower blade is important in deciding the quality of the cut, the life of your mower machine, it is important and vital that you pick a good quality one. In this buying guide, we will be discussing a few key factors that you should be considering while buying a new lawnmower blade.

Length of the blade

The first and foremost thing that you need to look for in a blade is its length. The typical lawn mower will have a blade length. General lawn mower blades fall within the blade length range of about 16.75 inches to 22 inches long.

While you will find a lengthy 21 inches or 22 inches blade to be convenient, please do not be misguided by taking longer blades thinking they are better but that’s not true. But they have to be of adequate size and the ones that fit properly. Shorter may not cut wider but wider may not fit easily too.

Width of the blade

The next thing to consider is the width of the blade. The typical width of the blade falls between 2.25 inches to about 3.5 inches. But as mentioned above, too wide of a blade might not fit in or end up damaging the mower. Also, too shallow of a blade can not help you cut better as well. Choose the size proposed by your lawnmower manual.

Size of the Deck

The next important thing that you need to consider is the size of the deck. This usually falls between the range of about 16 inches or 30 inches but longer is considered a bit better. But then again, like the width, check the fit as well. If you have a riding lawnmower, the size is picked better upside from there.

Total Number of Blades

This is more of a riding lawnmower thing but some handheld mowers too require multiple blade settings too but most of the time, they need just a single blade.

For riding mowers, you might want to have better push on the cut and this pick a total number that will match perfectly with the width of the deck of your mower.

Blade Holes

The holes in a mower blade refer to the latching holes that will grab onto the opening. Most of the blades have about 5 point opening whereas a few others come with 6 point openings.

Depending on the type and model of the mower you are using, you will pick the various type of blades with different holes. This information is neatly mentioned in the product literature of your lawnmower. Please make sure that you are choosing something that fits perfectly within the openings of the holes and the mower.

Blade Shape

The next important thing that you will consider is the shape of the blade. When you are buying a set of replacement blades, most of the times, we tend to replace the exact same type of blades we had previously. You need not necessarily buy blades that exactly resemble the original blades.

All you need to do is check if the original blades have a perpendicular blade shape or a parallel blade shape. Now you need to buy a batch that will match the shape type of the blade you currently have. It is ideal, but not a mandatory thing.

Build material

The last thing that you should want to consider is the material using which the blade is built. This is important as it can decide the life of your lawnmower machine as well. Treat the build material as an investment and then you will be gravitated towards picking a strong build material.

Stainless steel is the most preferred build material as it will aid in getting you a brilliant and sharp cut of the grass while not getting rusted easily as well. For the rusting part, good painting is preferred on the surface.


The Maxpower commercial Mulching blade set of 2 blades that are built for 42 inches cutting area. It is suitable for Poulan, Craftsman, Husqvarna for a variety of model numbers. It has star-shaped mounts with better range and great stainless steel build that makes it one of the best replacement lawn mower blades that you can buy online.

I wrote this guide because I’ve been there, and I know how important proper blade installation can be. After all, getting the installation right is critical for the life of the blade, the function of the lawn mower, and the appearance of your lawn.

In this guide you’ll learn:

  • Why lawn mower blade direction matters
  • How to tell which side of your lawn mower’s blade is up
  • And much more!

Why Does It Matter Which Side Of Your Lawn Mower Blade Is Up?

If you’re in a hurry, this video will help explain why it matters which side of your lawn mower’s blade is up, why it matters, and how to install the blade.

Use the Cutting Edge

Most walk-behind lawn mowers rotate the blade to the right, or clockwise. That means that when the blade is spinning, the cutting edge should spin to the right. However, this isn’t 100% foolproof.

Some lawn mowers do spin counterclockwise. It’s rarer, but you have to know which direction your lawn mower spins to be sure. Your lawn mower’s user’s manual should be able to tell you which direction the blades spin.

The Wings Face Up

On most lawn mower blades there will be a small part of the blade that isn’t flat, but angled up. This little wing on the blade is designed to encourage air movement, helping pull your grass upward for an even cut.

The wings on lawn mower blades are always designed to point up toward the lawn mower’s cutting deck. The same is true for the more extensive wings on mulching blades. If your lawn mower blade has wings, those wings should point toward the lawn mower and away from the grass.

Those three techniques should help you figure out which side of the lawn mower blade is up on pretty much any lawn mower blade. Assuming you know which direction your lawn mower spins the blade, that is the most fool-proof method, but the other two options are usually easier and faster ways to tell.

How To Tell What Kind Of Lawn Mower Blade You Need?

There are two basic kinds of lawn mower blade to choose between, and getting the right one can make a significant impact on your lawn mower’s performance. Most lawn mowers are compatible with both types of blade.

It’s important to remember that not all blades are created equal, and just because a blade is the right length doesn’t mean it’s compatible with your lawn mower. You always need to check your lawn mower for which blades are compatible.

Regular Lawn Mower Blades

Regular lawn mower blades are the simplest option. They are blades that are designed to get the job done without any bells and whistles or extra functions. These blades leave clippings relatively long, but they can also provide a more even mow than more complicated blades.

It’s important to have a good cutting edge on these blades since they are really reliant on cutting power to get good results.

Also called standard or medium-lift blades, these blades are typically on lawn mowers with side-discharge designs.

High Lift Blades

High lift blades are generally used for lawn mowers that have a bagging function because they provide more airflow that helps to move the grass clippings into the bag. These blades also provide higher suction, which means that they cut the grass at a more consistent height by pulling the grass up straighter.

Mulching Blades and Gator Blades

Mulching blades and gator blades both provide even more suction and cutting power in order to process the grass into smaller pieces. Of the two blade types, mulching blades are gentler. They process clippings into smaller chunks to distribute back over your lawn to act as a protective layer over the top soil.

However, mulching blades are not typically a good idea if you’re trying to bag your grass clippings at the same time. They just don’t move the clippings toward the bag very effectively.

Gator blades process the grass clippings even smaller than mulching blades. They are designed to get the clippings small enough to eventually mix into the top soil of your lawn where they will decompose and replenish the soil.

My Final Thoughts On Which Side Of The Lawn Mower Blade Is Up

Knowing which side of your lawn mower is up might seem like a simple thing, but it’s incredibly important. Choosing the right side of your lawn mower blade will help maintain the health of your lawn and can even reduce the maintenance on your lawn mower itself.

Learning how to install your lawn mower’s blade properly shouldn’t be difficult, but it is an important step if you want to keep your lawn mower in good condition. Hopefully this guide will help you decide which kind of blade is right for your lawn, and learn how to install it successfully.
