If you’re ready to replace your lawn mower blade, this step-by-step guide will take you through the process.

We’ll cover prepping for the job, unplugging the mower, turning it over, unscrewing the mounting bolt, removing the old blade, inserting the new blade, and securing the blade.

Let’s get started!

Short Answer

Once the spark plug is disconnected, use a wrench to loosen the blade nut and remove the old blades.

Next, place the new blades on the mower and secure them with the blade nut.

Finally, reconnect the spark plug and start the lawn mower to test the new blades.

Preparing to Replace the Lawn Mower Blade

Replacing the blade on a lawn mower is an important part of lawn care maintenance that requires proper preparation before beginning.

Before you start, make sure to put on a pair of protective gloves and goggles to protect yourself from any debris that may fly off the blade.

Additionally, make sure to unplug the mower from its power source to eliminate any risk of electric shock.

Once you have taken the necessary safety precautions, you are ready to begin replacing the lawn mower blade.

Unplugging the Mower

Before replacing the lawn mower blade, it is important to always unplug the mower from the power source.

This will reduce the risk of electric shock and also prevent the mower from accidentally starting while the blade is exposed.

If the mower is battery operated, simply remove the battery for additional safety.

To unplug the mower, simply locate the power cord and disconnect it from the outlet.

Make sure to store the cord in a safe place, and keep it away from any water sources that may cause a short circuit.

Once the mower is unplugged, it is safe to proceed with the blade replacement.

Turning the Mower Over

Turning the mower over is an important step in fitting a lawn mower blade.

It is vital to ensure your safety by unplugging the mower before turning it over.

To turn the mower over, make sure the area is clear of any debris and that the ground is level.

Place your hands on either side of the mower, lift the handle, and then tilt it back until the blade is exposed.

Make sure the blade is facing away from you to ensure your safety.

If the blade is too heavy to lift, use a flat-blade screwdriver to help you tilt the mower.

Once the mower is turned over, you can begin unbolting the blade.

Unscrewing the Blade Mounting Bolt

When it comes to replacing the lawn mower blades, one of the most important steps is unscrewing the blade mounting bolt.

The blade mounting bolt is located on the underside of the mower and is used to secure the blade in place.

Before attempting to unscrew the bolt, be sure to wear protective gloves and safety goggles to protect your hands and eyes from any flying debris.

Once you have the appropriate safety gear, its time to begin unscrewing the blade mounting bolt.

Use a ratchet or wrench to loosen the bolt and turn it counterclockwise until it is loose enough for you to remove it.

Make sure to keep your hands away from the blade as you do this, and be sure to keep the ratchet or wrench in a secure grip.

Once the blade mounting bolt is loosened, you can remove it and the old blade.

Be sure to keep the mounting bolt in a safe place, as you will need to use it again when you install the new blade.

After the blade mounting bolt is removed, you can move on to the next step in the process of replacing the lawn mower blades.

Removing the Old Blade

Removing the old blade from the lawn mower is the first step in fitting a new blade.

Its important to take the necessary safety precautions when working with a lawn mower blade so make sure to wear gloves and goggles to protect yourself.

Start by unplugging the mower and turning it over so the blade is exposed.

Next, look for the blade mounting bolt, which is usually located on the underside of the deck.

Unscrew the bolt with a socket wrench or Allen wrench, depending on the type of bolt used.

Once the bolt has been removed, the old blade should come off easily.

Be sure to dispose of it properly and in an environmentally friendly way.

If there are any pieces of the old blade left on the mower, make sure to remove them to avoid any damage to the new blade.

Inserting the New Blade

Inserting the new blade is the next step in replacing your lawn mower blades.

This is the part where you put in the new blade and make sure it is fitted correctly.

To do this, you need to wear safety gloves and goggles to protect yourself.

Once you have the safety equipment on, unplug the mower and turn it over so the blade is exposed.

Next, unscrew the blade mounting bolt and take off the old blade.

Then, carefully place the new blade into the opening.

Make sure the blade is correctly aligned with the mower deck and that it is flush with the deck.

Once the blade is in place, you can replace the mounting bolt and tighten it.

Once the blade is secure, you can turn the mower back over and plug it in.

After that, it is a good idea to give the mower a test run before you cut your lawn.

This will ensure that the blade is securely fastened and will help you avoid any potential accidents.

Securing the Blade

Once you have inserted the new blade and made sure it is flush with the mower deck, it is time to secure it.

To do this, you will want to use a wrench or socket set to screw the blade mounting bolt back in.

Be sure to apply the proper amount of torque needed to keep the blade fixed in place.

If the bolt is too tight, it can cause the blade to break or become unbalanced, leading to an uneven cut.

If the bolt is too loose, it can cause the blade to come off during operation and potentially cause injury.

So, make sure you have the correct size and type of wrench to ensure that the blade is securely fastened.

Once the blade is securely fastened, you will want to turn the mower back over and plug it back in.

Then, you can test the mower to make sure the blade is securely fastened.

This can be done by running the mower without any grass and checking to make sure the blade is spinning properly.

If all is good, you can now begin mowing your lawn.

Final Thoughts

Replacing the blades on your lawn mower is a simple task that will greatly improve the quality of cut when mowing your lawn.

Now that you have the step-by-step guide, you can go ahead and give it a try.

Make sure you wear safety gloves and goggles to protect yourself, and above all, be sure to securely fasten the blade before using the mower.

Your lawn will thank you for it!
