How to Sharpen and Balance Lawn Mower Blades: The Fast and Easy Way

Your soil is healthy, your new grass is coming up nicely, and it’s time to fire up the lawn mower for that first fresh cut of the spring.

But something’s wrong.

Your mower is vibrating, making odd noises, and just isn’t cutting right.

If your push mower is having these symptoms, it might just be the blades.

If your lawn mower blades aren’t balanced, your cuts won’t be even, your lawn mower won’t push well, and and you’ll likely end up wasting a lot of time.

Taking the mower to a pro will cost you both money and time. And that grass is growing higher and higher every minute.

Lucky for you, balancing your lawn mower blades is not too difficult if you’ve got the right tools and the know-how.

Let’s take a minute to learn about the lawn mower blades, how to assess them, and how to sharpen and balance them in no time.

Safety Warning

Before you read on just know that this can be a potentially dangerous DIY project if the proper precautions are not taken.

These are sharp blades that have the potential to hurt you if not handled properly.

Make sure to wear the cut resistant gloves and use a blade holder when handling the blades.

Always disconnect the battery and spark plug anytime you are doing maintenance on you mower.

What Does it Mean to Balance your Lawn Mower Blades?

Think about how your lawn mower works. A sharp metal blade spins at a very high speed around a central rod.

If the blade isn’t perfectly horizontal, it won’t cut your grass evenly. The blade will begin to wobble at very high speeds and cause noise, vibration, poor cutting, and possibly even injury to the operator.

Balancing your lawn mower blades makes sure the machine is running properly and keeps your push mower cutting quietly, evenly, and consistently.

How to Tell If Your Lawn Mower Blades Need to Be Balanced

There are a few common ways to tell if your blades need to be balanced.

Your blades need to be balanced anytime after sharpening them. The sharpening process removes metal from one side and therefore unbalances the blade.

That’s why mower blade sharpening and balancing should always go hand in hand.

An excessive vibration, wobbling, or rhythmic noise could all be indicators your blades aren’t balanced.

So if you think your blades are no longer balanced, what do you do?

How to Take Off the Lawn Mower Blade

The first step is to remove the current blades from your lawn mower. Take your mower it to a flat surface outside or in the garage to get started.

Disconnect the Battery

For safety, you want to make sure the lawn mower doesn’t wake up when you’re wrist-deep in the blades.

Disconnect the battery and spark plugs to make sure the mower stays off.

It’s also easier to remove the blades if the carburetor is on the high side when it’s tipped back.

Check for a Bent Blade

While the mower is in this position, rotate the bade by hand and see if the blade ends are flat and straight. If they are bent, then you will need a new blade. If they are straight, then keep going.

Indicate Orientation of Your Blade

Before removing the blade, use something to indicate which side of the lawn mower blade is up.

We recommend some tape, spray paint, or a marker. This will help you assemble the blade in the correct orientation later.

Remove the Blade

Use your safety gloves and goggles anytime you’re handling the blade.

Use your socket wrench, blade holder, and a little muscle to take the center bolt out of the blade. Be mindful of where you put your hand during this process.

Keep that bolt handy, you’ll need it later.

Now that the blade is removed, let’s sharpen it.

Do You Need a New Blade?

Before trying to sharpen the blade, you have to assess if it’s fixable or if you need a new one.

If your blade is bent, or if the trailing edge is too thin, it can shatter.

If the cutting edge is deformed, has low spots, or has any curvature to it, it’s time to scrap the blade.

You can always take the blade to your local hardware store if you’re unsure if you can sharpen it safely.

Assuming your blade looks okay, let’s move on to sharpening it.

Sharpening Your Lawn Mower Blades

Always use a blade removal tool and holder to position your mower blade when sharpening it. It’s very difficult and dangerous to sharpen it otherwise.

• For walk-behind and riding lawn mowers, single and twin blade models
• Holds blade in place for faster, safer removal
• Rigid metal construction
• Universal, fits most models
• Set of 2

Place it in the blade holder with the blade-side facing upwards. Use a straight file and push it against the blades in and in an upward direction – starting with the file closer to you, then extending your arm.

Only file in this one direction, not back the other way.

It shouldn’t take long to completely sharpen the blades. You’re not trying to make it as sharp as a chef’s knife, more like a butter knife.

When you’re satisfied with the sharpness, it’s time to move on to balancing the lawn mower blades.

Balancing Your Lawn Mower Blades

Remember that the blade is like a seesaw. If there’s a heavier side of the blade, the lawn mower will not work correctly. The good news is, this seesaw design is easier to balance.

The easiest option is to use a lawn mower blade balancer.

This is a cone shaped metal object designed to accommodate any sized blade axis hole opening.

Position the blade balancer on a level table ad then place your lawn mower blade onto the balancer.

If the blade is balanced, it will stay level and on the balancer even when you spin it.

If the blade is unbalanced, the heavier side will fall down towards the table, especially as it spins.

If the heavier side falls down, it’s time to take the blade back to your blade holder and sharpen the heavier side down until it evens out.

Repeat this process until the blade balances itself horizontally when still and when gently spinning.

Now your blade is sharpened and balanced, it’s ready to get re-installed!

Re-Assembling Your Lawn Mower Blades

Carefully take your blade back to your mower while wearing your safety gloves.

Don’t forget the bolt and your blade holder.

First-Time Lawn Mower Buyer? Here’s How To Pick the Right Mower for Your Lawn

Choosing the right lawn mower for your first home or rental doesn’t have to be a challenge. Knowing the size of your lawn, your limitations, and your budget can help.

Ok, so you bought your first home, your grass is getting unruly, and you don’t have a lawn mower for routine lawn maintenance. Don’t dwell on those stares from Chuck and his “perfectly manicured lawn”; you can get the right tool to kick your grass, too. So how do you pick the correct self-propelled, electric riding mower, lawn tractor, or zero-turn mower for your lawn?

How do I know what mower to buy?

First-time lawn mower buyers should take factors like their level of mobility, lawn size, topography, and budget when choosing the right mower for your landscape. For instance, a suburban home with a ¼ acre of lawn space probably doesn’t require a high-dollar riding mower.

However, if physical concerns preclude you from pushing a self-propelled mower, a small riding mower can speed up your lawn maintenance and take the strain off your back and knees. over, a riding mower or lawn tractor with a hydrostatic transmission and 22 horsepower will have little issue traversing steep hills on a sloped property.

Still, electric self-propelled units take swappable power packs like the RYOBI 40V batteries. Better yet, some can cost under 200 and tackle a small lawn with relative ease.

What is the right size mower?

According to Popular Mechanics, ¼ acre lawns or smaller are self-propelled territory. Further, anything above that size might warrant a riding or zero-turn unit for ease, time management, and comfort.

Of course, these are simply guidelines. Some owners with large properties might not have the budget for a gleaming, new commercial zero-turn mower. In those cases, a preowned model or having the patience to use a riding mower is an option.

Additionally, zero-turn mowers tend to have the easiest time balancing large lawns and tight spaces. Still, zero-turns are often more expensive than lawn tractors. For instance, Lawn Love says the average lawn tractor costs around 3,515. However, the average zero-turn costs about 1,535 more than the home-use tractors, for a total of 5,050.

What type of lawn mower is easiest to use?

The easiest lawn mowers to operate and maintain are small, self-propelled units. Furthermore, some of the most straightforward mowers today are electric models, like the EGO Power and RYOBI Dual Blade 21-inch self-propelled mowers. Both models earned top scores from The Spruce for ease and performance.

over, manufacturers like CRAFTSMAN, Toro, and Honda produce many gas-powered mowers with decks larger than 20 inches. While running a tool with an internal combustion engine (ICE) isn’t as straightforward as seating a removable lithium battery, these gas-powered units are cheap and straightforward.

When it comes to choosing a lawn mower for home use, most American renters and homeowners will get the job done with a self-propelled unit. However, in some rural and large-lot landscapes, a small-deck application might not cut it.

What is Mower Blade Balancing?

Making sure the weight of your blade is distributed equally from one side to the other is all that is required to balance your blades.

When you remove more metal from one side of a blade than the other during the sharpening process, the blade usually becomes imbalanced.

The Importance of Mower Blade Balancing

It’s important to know the importance of mower blade balancing because it can affect both the quality of your trim or cut and the wear and strain on your mower.

Because of this, an unbalanced lawnmower blade can result in a number of problems, such as internal structural bolts snapping or losing, giving you more work to do, or producing a lot of vibration, which will in turn place stress on the blade shift, the spindle, and, in most cases, the engine.

Tools and Materials Needed for Mower Blade Balancing

Here are some tools and materials you should keep in hand when you plan to balance mower blade:

• Safety Gloves
• Blade Holder
• A File, Grinder, or Sharpening Stone
• Medium Flat File
• Spanner
• Goggles or Other Safety Glasses
• Steel brush
• Socket Wrench

How to Sharpen Lawn Mower Blade?

Follow these steps explained below on how to sharpen a lawn mower blade to get a clean cut:

Assemble all Your Work Equipment

You require both your work equipment and personal protection equipment to maintain the highest level of safety.

A steel brush, a wrench to remove the blade, safety goggles, ear muffs (if you’re using a grinding machine), a bench grinder or sharpening equipment of your choosing, and a blade balancer are among these.

Disconnect the Spark Plug

This will stop the motor from starting by accident. Tape the spark plug wire back after removing it from the plug to prevent it from falling back and making contact with the plug.

This could be a good opportunity to examine your spark plugs and, if necessary, clean or replace them.

Tilt Mower on its Side

In order to place the carburetor and air filter upwards and avoid any oil or gas from dripping into the air filter, tilt the mower onto its side while ensuring sure it is horizontal and on a flat surface.

After that, while holding the blade, remove the screw by using a wrench to loosen it.

Remove the Blade

Wedge a short 2×4 between the blade and the deck to clamp it.

Use a long-handled wrench to loosen the nut. The bolt and blade can be removed by turning counterclockwise.

Remove Dust and Debris

Now dust off the rust and debris from your blade using your steel brush. To find out if the blade needs to be replaced, inspect it carefully.

Sharpen the Blade

Sharpen the blade along the original angle of each cutting edge using your file or grinder. Make sure to keep the original angle, only file in that direction, and remove an equal amount of steel from each edge.

Don’t sharpen the bottom of the blade, and be sure to remove an equal portion of metal from both sides!

Mark the New Blade

Reinstalling a sharpened mower blade upside down after sharpening it is a common mistake made by lawn owners. The blade won’t cut after it is reinstalled upside down.

Before removing the sharpened blade, spray paint it. It will help you in learning how to reinstall it properly.

Check Blade Balance

Don’t forget to check the blade balance!

To make sure the blade is balanced, place it on a nail. If a blade part dips, file it off to make the blades even.

Reinstall the Blade

Screw in the bolt or nut and reinstall the blade on your lawnmower. In order to press down on the breaker bar and tighten it, insert the 2×4 in the opposite direction.

Make sure the bolt is correctly tightened because a loose blade may cause the engine timing to be wrong, which will make it difficult to start the mower. You can also get professional help to avoid accidents of any sort by getting a lawn mower blade balancer for accurate results.

Here’s the best for the mower blade balancing.

How to Balance Lawnmower Blade After Sharpening?

It’s likely that you won’t evenly sharpen your lawnmower blades if you do it yourself. Uneven sharpening can make a blade heavier on one side than the other, which can lead to heavy vibration, the eventual loosening of certain important internal bolts, and faster engine wear and tear.

Here’s a step-by-step guide that will help to deal with damages:

Fasten Blade Over a Nail Head

Put a large nail into a wall plank in your garage or shed using a hammer.

Put the hole in the center of your lawnmower blade over the nail head to balance it on the nail base.

Rotate the Blade

Watch what happens if you try rotating the blade a quarter turn to the right. If it maintains its position, it is balanced, and there is no need for concern. It’s a negative omen, though, if it spins back to where it started. Turn the blade halfway to the right once more.

The blade is balanced if it stays in position, but if it continues going back to the bottom, the blade is out of balance and the portion that keeps going back down is excessively heavy.

File the Blade

Remove the blade from the nail after identifying the heavy area and secure it to a workbench or other sturdy surface. Make sure you keep an eye on the heavy portion of the blade. File the edges of the blade’s heavier part down with a smooth file.

As you file, make an effort to keep the blade edge’s normal angle.

Check for Balance

Remove the blade from the clamp and use a brush or your hands to gently clean it. Return to the joist and set it on the nail head there.

Check to see if the same section keeps falling to the bottom by spinning the blade once more.

Repeat Procedure

Reinstall your blade once both pieces are balanced. If not, keep filing the blade and balancing it on the nail alternately until it stays in place on both portions. Reinstall the blade on your lawnmower once you are certain that it is balanced, then use it as normal.

You can look forward to seasons of a perfectly cut lawn if you have the expertise of sharpening your lawnmower blades and balancing.

Depending on the particular mower type and its settings, a mower blade’s spinning speed can change. Typically, lawnmower blades rotate between 2,500 and 3,500 revolutions per minute (RPM). Using an unbalanced blade can lead to serious consequences for both the lawn mower engine and blade shaft.
