Maintaining a well-kept lawn requires the use of a lawn mower. Over time, the blades on your lawn mower may become dull or damaged and need to be replaced. Removing the lawn mower blade can seem like a daunting task, but with the right tools and techniques, it can be done easily and safely. In this article, we will discuss how to remove a lawn mower blade step-by-step.

How to remove lawn mower blade

If you are having difficulty removing the lawn mower blade, first make sure that there is no debris blocking the blade’s path. Next, use a pair of pliers to grip either end of the blade and twist it counterclockwise. Finally, use a screwdriver to pry the blade loose from the lawn mower.

Step 1: Prepare the Lawn Mower

Before starting to remove the lawn mower blade, it is important to ensure the lawn mower is turned off and the spark plug is disconnected to prevent any accidental start-ups. Also, tilt the lawn mower to its side with the air filter and carburetor facing up.

Step 2: Remove the Blade Nut

Use the wrench or socket set to loosen the blade nut by turning it counterclockwise. In most cases, the nut will be on tight, so make sure to apply enough pressure to break it loose. Avoid using too much force as this could damage the nut or bolt.

Step 3: Remove the Blade

After loosening the blade nut, remove the blade from the lawn mower deck. To do this, gently pull the blade down and off the spindle. If the blade is difficult to remove, use the block of wood to wedge the blade to prevent it from rotating.

Step 4: Inspect the Blade

Once the blade is removed, inspect it for any damage, cracks, or dullness. A dull or damaged blade should be replaced to ensure the lawn mower is operating efficiently and effectively.

Step 5: Replace the Blade

If the blade is damaged or dull, it should be replaced. To replace the blade, align the center hole of the blade with the spindle and slide it onto the spindle. Make sure the blade is facing in the right direction, which is usually indicated by an arrow on the blade.

Step 6: Tighten the Blade Nut

After the blade is replaced, use the wrench or socket set to tighten the blade nut by turning it clockwise. Make sure the nut is tightened securely to prevent the blade from coming loose while mowing.

Step 7: Test the Lawn Mower

Before using the lawn mower, test it to ensure it is operating properly. Start the lawn mower and allow it to run for a few minutes to ensure the blade is spinning correctly.

What are the different types of lawn mowers?

There are many types of lawn mowers on the market, so it can be hard to decide which one is right for you. Here are four different types of lawnmowers:

Electric Lawn Mower: These machines use electric power to cut the grass. They’re convenient because you don’t have to lift the blade, and they’re usually quieter than gas-powered mowers. However, they require regular maintenance, so make sure to clean the cutting blades and battery compartment regularly.

Gas Lawn Mower: These machines use gasoline or oil to power the blade. They’re cheaper than electric lawnmowers, but they also require more work since you have to fill the gas tank and change the oil often. They’re usually louder than electric lawnmowers and tend to leave a larger trail in the grass.

Powered Push Mower: These machines use an engine or motor that’s either self-propelled or push-driven. They’re typically easier to operate than other types of lawnmowers, but they can be less powerful and less durable than other types of machines.

Clutch Mower: A clutch mechanism allows you to slow down or stop the blade once it’s started rotating. This type of machine is typically easier to control than other types of lawnmowers because you don’t have to keep your hand on the throttle all the time.

Tips to keep your lawn mower blade sharp

If your lawn mower blade is not cutting the grass evenly, it may be because of a dull blade. Sharp lawn mower blades reduce the amount of time it takes to cut the grass, which saves you time and energy. Here are some tips to keep your lawn mower blade sharp:

Always sharpen the blade before each use. A dull blade will take longer to cut through the grass and will produce more clumps.

Keep the blade clean. Dirty blades cause drag and resistance when cutting through the grass, which can make the job harder than it needs to be. Clean the blade with a damp cloth after every use and store it in a clean area to prevent rusting.

Maintain tension on the blade while using it. Loosen or adjust the blade tension if it’s seems too tight or if it’s producing poor results when cutting through the grass.

How to sharpen lawn mower blade

There are a few ways to sharpen lawn mower blades. The most common way is to use a sharpening stone, but there are also electric sharpeners and manual sharpeners available. Sharpen the blade until it’s sharpened to the correct edge angle.

For standard lawn mower blades, 18 degrees is usually correct. If you’re using an electric or manual sharpener, use the manufacturer’s instructions for the best results. When removing a lawn mower blade, it is important to take the necessary safety precautions to prevent any injuries. Wear gloves to protect your hands and safety glasses to protect your eyes. Also, disconnect the spark plug wire to prevent the engine from accidentally starting.

Avoid touching the blade with your bare hands as it can be sharp and cause injury. Use a block of wood to prevent the blade from rotating when removing or installing it. Additionally, always make sure the lawn mower is turned off and the spark plug wire is disconnected before removing the blade.If you’re using a sharpening stone, use a light touch and move the stone slowly back and forth across the blade.

For electric sharpeners, hold the blade at a 15-degree angle to the sharpener and use short, quick strokes. For manual sharpeners, hold the blade at a 20-degree angle and use long strokes.

How to repair lawnmower blade

There are several ways to repair a lawn mower blade. You can either replace the entire blade or just the broken section. If the entire blade is broken, you’ll need to replace the whole unit. If just the broken section is damaged, you can fix it with a new blade.

How To Sharpen Your Lawn Mower Blade Without Removing It? (2023 Guide)

Keeping your lawn mower blade sharp is critical to keeping your lawn looking as good as possible.

Not only do sharp blades cause less damage to the grass you’re cutting, but they also do a more even job which helps to keep your lawn looking better after you’ve finished.

Of course, grass doesn’t cut easily and is full of little silicate particles that dull your lawn mower’s blade over time.

That means that you need to sharpen your lawn mower blade regularly if you want to maintain peak performance and keep your lawn as healthy as possible.

You could send your lawn mower’s blade a professional to get it sharpened, or pay for replacement. Or, you can go the more cost-effective route and sharpen it yourself at home.

You can even sharpen your lawn mower blade without having to remove the blade from the lawn mower. This guide will show you how, though I still recommend taking the blade out for a more complete sharpening every once in a while.

In this guide you’ll learn:

  • How to sharpen your lawn mower blade
  • Why it’s important to sharpen your lawn mower blade
  • And much more!

Why Do You Need To Keep Your Lawn Mower Blade Sharp?

Grass has evolved to have small silicate particles embedded throughout the leaves. It evolved that way to help discourage herbivores from eating the leaves as they grow. Even though that adaptation wasn’t very effective, there are still plenty of herbivores who are capable of eating grass, it has a big impact on the tools we use to keep and maintain our lawns.

The biggest impact of those silicate particles is that lawn mower blades dull rather quickly compared to other blades. Your lawn mower’s blades don’t have to be incredibly sharp to be effective, but once they get too dull they start tearing and shredding your grass instead of cutting it.

Once your lawn mower blade has started shredding your grass, it’s harder for your grass to keep your lawn growing. You may even start to see yellow-green tips and other signs of disease in your lawn. That’s because ragged ends are harder for your grass to close, harder to heal, and more vulnerable to infection.

Keeping your lawn mower’s blade sharp is also important for the lawn mower itself. A dull blade can put more stress on the moving components of the lawn mower, including the motor, leading to higher maintenance requirements and more expensive kinds of maintenance over time.

Keeping your lawn mower blade as sharp as you can is a good way to make sure your lawn and your lawn mower are in the best possible condition.

Are you comfortable taking your lawn mower’s blade off? This video shows how to sharpen a removed blade. It also gives some good tips for how to get your lawn mower ready and when to sharpen your lawn mower’s blade.

Run the rotary tools sharpener down the blade a few times until the blade is visibly sharper. It should only take 2 to 3 repetitions and only a couple of minutes per side to get this done.

Once you finished sharpening the blade, clean up any metal shavings that are still on the undercarriage for on the lawn mower blade itself. Turn the lawn mower back upright and reconnect the power source and fill the gas tank if needed. You should be ready to mow with your freshly sharpened blade.

When Does Your Lawn Mower Blade Need Sharpening?

Knowing when to sharpen your lawn mower blade can be a little bit of an art rather than a science. That’s because different kinds of grass dull your lawn mower’s blade at different rates. Combine that with different lawn mower motors, different blade materials, and different blade designs and you have a recipe for very varied sharpening schedules.

There are some general rules you can follow to make sure sharpening the blade at the right time. These are good guidelines, but if you think your lawn mower blade needs sharpening you’re probably right.

I like to sharpen my lawn mower blade just as I’m starting to mow my lawn in the spring. It helps make sure my lawn is off to a good start every year, and also gives me a chance to look over my lawn mower for any signs that it needs maintenance before mowing season starts.

After that, your lawn mower’s blade should be sharpened every 20 to 25 hours of use. For some people, that means that you’ll only sharpen your lawn mower blade a couple of times a year. For other lawns, you may need to sharpen the blade several times a season. That’s why some guides, like this guide to lawn care, recommend sharpening twice a season.

Of course, the quality of your blade’s original edge and the quality of the material itself can impact how often the blade needs to be sharpened. High-quality metal and a well-ground edge will always last longer than than soft metal or a badly sharpened edge. Some grass types may also wear through your blade’s edge faster.

Because of that variability, I recommend you pay attention to your lawn mower’s performance on your lawn. If you start to struggle to get an even cut, it’s time to sharpen the lawn mowers blade. Pay attention to how long you can go between sharpening to develop your own customized schedule.

Just remember that the more often you sharpen your lawn mowers blade the more often you’ll have to replace it. That’s because sharpening takes off a small amount of metal every time. As you start to strip the metal away, the blade will get less effective and more brittle.

Eventually, after sharpening your blade several times, it’s better to just replace and get a new blade than to keep trying to sharpen it.

Don’t be surprised if your sharpening schedule changes when you change lawn mower blades. That’s the different metal qualities and blade edges at work. Even if you buy the same model of blade it’s possible that the manufacturer will have changed processes and that the new blade will need a different maintenance schedule.

My Final Thoughts On Sharpening Your Lawn Mower Blade Without Removing It

Keeping your lawn mower blade sharp doesn’t have to be difficult. Sharpening your lawn mower’s blade without removing it is quick, easy, and very effective.

It’s one of the simplest ways to keep your lawn mower’s blade in good condition without just replacing the blade.

Plus, your grass will definitely appreciate the sharper blade. It will be healthier, grow faster, and less vulnerable to disease when you keep your lawn mower’s blade in good condition.
So, now that you know how I know how easy it can be there’s nothing to get in your way.

Keep your lawn mowers blade sharp, keep your lawn mower effective, and enjoy your beautiful lawn.

Spindle Turns When Removing Blades – How to Stop It

You’ve noticed that the blades on your riding mower aren’t cutting all that well and decide it’s time to remove them to sharpen them up. You’ve been through this process dozens of times before. You block the blade with a piece of 2×4 and a clamp and set to work on removing the bolt. But you run into a problem you’ve not experienced below. The spindle turns when attempting to remove the blade. So the bolt itself just spins and spins; there’s no resistance. How are you going to get it off?!

While a lawn mower blade bolt that’s stuck is not too uncommon, the issue of the spindle turning when removing mower blades is less common. I have got a few ideas you can try to fix this issue though.

How to Fix a Spindle that Turns When Removing Blades

This problem shouldn’t be confused with that of a lawn mower blade bolt that is stuck and won’t budge whatever you seem to do. That’s another problem. With this issue, we need to stop the spindle from spinning so you can get enough torque on the blade bolt to remove it.

Here are a few ideas on how you might do that.

Use a Wide Grip Wrench on the Spindle

It’s clear that you need to secure the spindle in some way so that it is not able to spin. The most obvious way to do that is by using a wrench and clamping it in some way.

You’re going to want to remove the pulley from the spindle first though. Trying to clamp the pulley is definitely not a good idea, as you’ll almost certainly end up damaging it, and then you’ll have a whole other problem to try and resolve.

Once the pulley is out of the way and safely put to the side, clamp the spindle with the wide grip wrench. Make sure it’s locked on there tight, as you don’t want it slipping. If you have a smaller deck, you may not need to do anything else, as the sides of the deck will lock the wrench in place. If you’ve got a bigger deck, however, you may need to add an additional clamp onto the side of the deck to lock the wrench up against it.

This should prevent the spindle from turning when removing your blade. If you’re having trouble budging the bolt with a regular socket wrench, try using an impact wrench instead. The extra torque they can add will usually loosen even the most stubborn of bolts.

Engage the Clutch to Provide Resistance

This tip is only worth reading if you have a manual clutch as opposed to an electric clutch. If yours is electric, skip this one.

For this you are going to want to have your mower shut off. You’re then going to want to engage the clutch. In theory, this should prevent the pulley and spindle from moving as the main engine drive pulley won’t spin. At the very least it should provide some extra resistance and if you use a good impact wrench on the blade side, it might just do the trick.

Grind the Head of the Bolt Off

I should preface this by saying that I’ve never done this myself. I’m actually a little bit scared of doing so. The paranoid part of me thinks I’ll take too much off and then I won’t be able to get the body of the screw out.

But this is what I’ve seen a lot of folks recommending you do if you have a mower whereby the spindle turns when removing blades. You need to carefully grind the head of the bolt off and then leave it to cool down. You’ll still have the thickness of the blade and washer poking out of the threaded hole, which is enough for you to grab hold of and turn. You could use a pair of pliers too (I always find this stuff easier with pliers…damn small hands that I have!).

Final Thoughts

There you have it. A spindle that turns when removing blades can be a real head-scratcher at first, but it’s not a lost cause. You have options, namely:

  • Locking the spindle up with some sort of wide grip wrench
  • Engaging the clutch to provide the necessary resistance
  • Grinding the head off of the bolt

Once you manage to get the bolt off, I’d also check out the condition of the spindle bearing. It may be worn and need replacing.

About Tom Greene

I’ve always had a keen interest in lawn care as long as I can remember. Friends used to call me the “lawn mower guru” (hence the site name), but I’m anything but. I just enjoy cutting my lawn and spending time outdoors. I also love the well-deserved doughnuts and coffee afterward!

Комментарии и мнения владельцев

My nut on the blade turns but doesn’t come off. I think the spindle may be turning also. Suggestions?

Hi Ben, If you have a vertical drive shaft connected directly to the engine, then you can take a look at the top of the engine. If the flywheel is turning, then when you turn the bolt it is still tight. If you have a bolt connecting the blade to a pulley, then take a look at the top of the pulley. If the pulley is spinning as you try to loosen the bolt, then again the bolt is tight and your attempt at loosening the bolt isn’t working. The best way to get the bolt out is to lock the blade so it can’t move, then attempt to loosen the bolt. If this fails, you might need to put a wrench on the top of the pulley/flywheel to stop the spindle/driveshaft from spinning. Good luck & Tom.
