What to Consider When Buying the Best Lawn Mower Blades

Buying the Best Lawn Mower Blades
  • Model – While some replacement mower blades fit a wide range of lawn mowers, others are manufactured specifically for a certain brand or model. Be sure to check that it’s compatible with the exact model you have before you buy.
  • Material – A good quality blade will cut effortlessly through grass growth and last a long time, so it’s worth paying the extra cost. The best bet is a high-grade stainless steel with an anti-rust coating.
  • Length – Blade length determines the length of the trim, but longer blades are not always better. The most important thing to do is check your mower to see what size blades it takes. This will range from model to model from about 16.75 inches all the way up to 22 inches.
  • Deck Size and Mower Type – Different blades have been developed for self-propelled electric lawn mowers and riding mowers, as well as mowers with different deck sizes, so it’s important to know what your current mower’s deck size is.

Importance of Sharpening Your Lawn Mower Blade

A lawn mower blade that is not well maintained, has the tendency to slash the grass blade's edges. This will, in turn, leave your grass torn instead of having a clean cut.

The torn part will turn brown after a few days, which will make your lawn susceptible to diseases and pests. That is why it is best to sharpen the blades of your lawn mower for your grass to get a clean cut, which will help reduce stress and damage.

How To Inspect Your Blade

At the start of the season for mowing, it is best to inspect your blades thoroughly for signs of dents, nicks, and even blends. You also need to make sure that your blades are properly balanced and correctly sharpened before you use it to work on your lawn.

Besides inspecting the blade, it would also be ideal to check the lawn for sticks, rocks and any other debris that can nick your blades, while mowing your lawn.

Balancing Your Lawn Mower Blades

While it is important to make sure that your blades are well sharpened, it is also important to ensure that your blades are balanced. The reason behind this is because an unbalanced one can cause the engine to get stressed and as well as the cutting deck.

You can do this by using a blade balancing tool, but if you don’t have this kind of device, then a grinder will do.

How to Sharpen Your Lawn Mower Blades

Now, for your lawn mower blades to be sharpened correctly, there are some tips that you need to do for you to ensure that you are doing the right thing. The reason behind this is because not knowing how to properly do it will only cause for your blades to get damaged. 

Here are some tips on how you can effectively sharpen your blades for your lawn mower. 

1. Remove the Lawn Mower's Spark Plug

The first thing that you need to do is to remove your lawn mower’s spark plug. This will help prevent the motor from starting accidentally, which can cause serious injuries. You can tie or tape it back so it won’t be able to flop back and come in contact with your plug.

2. Removing the Lawn Mower Blade

You can access the lawn mower blades by turning the mower to the side. But always make sure that the air filter and carburetor are facing up to avoid any oil spill from the engine.

These two parts are housed in a boxy plastic case beside the engine. If you are unsure on where to locate it, you can check the manual of your lawn mower or contact the manufacturer.

Here’s a video on how to properly remove the lawn mower blade.

3. Marking the Blade

To avoid making the mistake of reinstalling the blade in the wrong position, mark the blade’s downward side. Reinstalling the blade the wrong way will just make it useless.

You can mark the blade using a spray paint, but this doesn’t mean that you have to paint the entire part of the blade, a little dot will do. You can also use a pen or a single tape so that you can mark the blade.

4. Safely Mobilize and Clean the Blade

Most blades are secured using a bolt, and for you to be able to remove the screw, it would be best to immobilize it. This will help the blade to be steady while you are loosening the bolt. You can use a clamp or a vise if you find this convenient.

5. Sharpening Using a File

You can start sharpening the blade using a metal file by stroking from the inner edge of the blade to the outer part until it gets shiny and clean. You can repeat filing the blade on both sides until you get the desired shininess that it has.

When sharpening your blade, you also need to make sure that the file is at an angle of the blade’s bevel while you are sharpening it. Typically the angle of the blade is 40 or 45 degrees, though there are some instances that the angle is different, so it is best to check the manual.

6. Reinstalling the Blade

Before installing the bolt to the blade, it would be best to use a sealant or a lubricant to make sure that it won’t rust. Once done, you can reinstall the blade and take note of the mark that you made earlier.

Always remember that the sharp part of the blade should face the spin’s direction or the direction where the portal of the grass catcher is. Lastly, when tightening the bolt, always make sure to use a racket or a wrench, instead of a hammer.


Here are some other tips for you to familiarize yourself with your lawn mower’s blade:

Adjusting a Lawn Mower Blade

Balancing Your Lawn Mower Blades

For you to be able to change the blade, you need to find the lever which is usually located on the mower’s side. For people who have lawn mowers that can be driven, the lever will usually be found on the side where your leg is.

Once you have located the lever, you can start pulling it down for you to be able to create a cut or pull it up for it to remove lesser grass.

Changing Your Lawn Mower Blade

There will come a time, which you will need to modify the blade of your lawn mower because of particular problems. When changing the blade, you need to make sure that the mower in unplugs for it to turn on and injure you accidentally. 

  • Remove the old blade and as well as the bolts, since you will need the bolts for the new blade that you are going to install.
  • The new blade should be slid over the mower’s spindle, once you’re done, you can put the bolt back to the pivot screw.
  • Tighten it using a wrench but make sure just to tighten it enough, since you don't want to end up having a loose bolt.
