What to Consider When Buying 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 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. You also need to ensure that your blade is well balanced because if not, it will only make the mower vibrate, which will then damage the mower’s internal parts.
To do this, you can use a balancer, which you can purchase at hardware stores or gardening centers. For people who don’t have a balancer or ones who does not want to purchase, then using a wooden dowel will do.
If you notice that the blade is tilting high, you can start filing the opposite side. You can continue filing it until the mower’s blade has already lie flat.
Here are some other tips for you to familiarize yourself with your lawn mower’s blade:
Adjusting a Lawn Mower Blade
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.

How to Sharpen 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.
1. Disconnect the Plug and Power Source
The first thing that you need to do is to disconnect the plug and as well as the power source of your lawn mower as this can cause problems while you are working on it.
You can easily disconnect the plug by removing the wire that is prominent on the front or side of the engine’s lawn mower. Even after you have disconnected everything, you still need to wear eye protection and gloves to stay protected.
2. 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.
3. Access the Blade of Your Lawn Mower
For you to be able to access the blade, turning the lawn mower to its side is ideal. Avoid haphazardly turning the mower as the oil of the engine can spill to the air filter and carburetor.
The air filter and the carburetor by most of the mowers today are located in a boxy case that is made out of plastic and is on the side. You can check the manual if you are unsure about its location.
You may also opt to pour the mower's oil in a separate container to ensure that there will be no spillage no matter how you turn it.
4. Mark the Blade's Side that is Facing Downward
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.
5. Blocking and Loosening the Bolt
Now once you see the blade, you need to loosen the bolt that secures the blade. For you to easily do this, you can block the blade using wood for it to avoid moving.
In this way, you can easily remove the blade using a ratchet or a wrench. There are lawn mowers that have a threaded nut that is reverse which will help in holding the blade to the spindle.
Once you have to remove the bolt, you need to remember all the orientation and placement of the plates and washers that will come with the blade.
6. Cleaning and Sharpening the Lawn Mower Blades
Now that you have removed the blade take some time to clean it. You need to remove grime, grass clippings, rust or anything that is making the blade look dirty.
You can use a glove for your hands and a dry clean rag. But if you haven’t cleaned the blade for quite a long time, then it would be best to use soapy water and sponge to help remove any grime and materials that have accumulated. Once done, make sure to wipe dry your blade.
Sharpening with the Use of a Bench Grinder
You can start sharpening the blade on the grinder by moving it back and forth. You need to carefully maintain the blade’s angle while you are sharpening it.
You may also opt to use a hand grinder that is equipped with a metal wheel to sharpen the blade.
Sharpening with the Use of a Belt Sander
You can also sharpen the blade of your lawn mower by using a belt sander. Start rubbing the blade at the right angle against a sandpaper that is abrasive as this will sharpen the blade gradually.
Once done, you can start inverting the blade of that the belt sander is facing up, while the lock’s switch will be turned on.
Sharpening with the Use of 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.
When using a file, it would be best to use a face mask since there will always be dust that will be produced. The mask will help protect your lungs against metal particles and airborne dust.
7. 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.
