If you are not sure whether or not changing your own lawnmower blades is something that would interest you, then read on and we will discuss why this is a good idea for anyone who owns their own home or works on their own property.

What Is A Lawnmower Blade?

A lawnmower blade is a metal blade that is attached to the bottom of a lawnmower. The purpose of a blade is to cut grass as it slices through the blades horizontally, just like scissors would cut paper.

When operating properly, your mower’s blades will rotate around the axle so that it can slice through any unwanted vegetation on your property.

How Do I Change My Lawnmower Blade?

Remove the old blade. Unscrew the bolts holding the blade in place and pull it out of its bracket. Check to make sure that you’ve removed all parts of the old blade, including nuts and washers.

Clean your deck. Use a pressure washer or stiff brush to get rid of dirt and grass clippings from underneath (and behind) your mower deck before installing a new blade. This will help prevent rusting while protecting its finish as well as improve airflow for better engine performance when cutting grass next time around!

Install a new blade in reverse order of removal: Slide rubber washer over shaft first then secure with nut onto threaded end; repeat process until both sides are secured together tightly enough so they won’t come apart again easily once finished installing them onto either side before tightening down completely by hand.

How to Remove and Replace Lawn Mower Blades

Is It Safe To Change My Own Lawn Mower Blade?

You should be able to change your own blade. However, if you don’t feel like taking on this task, there are professionals who can do it for you.

The cost of having someone change the blade varies depending on where you live and what kind of equipment they use. You may also have to pay extra for new parts if your current blades need replacing due to wear or damage.

What Kinds Of Blades Are There For A Lawnmower?

There are many different kinds of blades for a lawn mower. The type of blade you choose depends on your lawn. You can choose from a number of different materials. They can be made of steel, aluminum, or plastic. 

The thickness will depend on whether you have a thick or thin lawn and how much grass it will take to get the job done.

“Breaking a lawn mower while doing maintenance work like changing blades can be frustrating. But don’t worry, our tips on how to avoid breaking a lawn mower are here to help. Check out our guide on how to avoid breaking a lawn mower to learn more.”

How Should I Store My Lawn Mower Blade?

Keep the blade clean and dry. After you’ve finished mowing, make sure to wipe off any grass clippings from the blade with a rag or towel.

If it’s not too wet outside, you can hang up the mower in its shed for storage until next time; otherwise, keep it under cover somewhere so that no rain will fall on it.

Don’t store your lawnmower in an enclosed area like a garage or even shed during winter months because it could collect moisture from condensation and freeze when temperatures drop below freezing overnight not only will this damage your machine but could also cause flooding if there’s been any water buildup around where you keep it stored (and potentially ruin anything else inside). 

Instead, leave yours outside where there’s plenty of ventilation during cold weather months so that any excess moisture gets dispersed into thin air instead!

Where Can I Buy A New Lawn Mower Blade?

You can buy a new lawn mower blade at any home store or hardware store, such as Lowe’s or Home Depot. The blade will be in the lawn mower section of the store, along with all other accessories needed for your lawnmower.

What Kind Of Oil Should I Use On My Lawn Mower Blade?

The last thing you want to do is use too much oil, as this will just drip down the side of your lawn mower. Also, make sure that you are using a high-quality oil that has been specifically designed for lawn mower blades. You should never use motor oil on your lawnmowers as it can damage them!

What Kind Of Blade Is Best For Your Lawn?

The type of blade you need depends on the type of grass you have and how often you mow it. Thick-bladed lawns require a sharp, heavy-duty mower. 

Shorter grasses require lighter blades with more life in them, so they will be less likely to break when cutting through dense stands of weeds or clumps of dirt. 

If your lawn is mixed with different types of grasses, choose a blade that’s made for specific types like Bermuda or zoysia and for different lengths at each end: one for tight spots near walls and fences; another for wider swaths across open spaces between trees (to avoid damage from bumps).

What Kind Of Blade Will Last The Longest?

There are many types of lawn mower blades available on the market today. Choosing the right one can be difficult, especially if you’re not familiar with all of them. When choosing a new blade, it’s important to think about what kind of work your lawn requires and how best to accomplish that job. 

If you have thick grass or weeds growing in your yard, then a mulching blade may be ideal for you because it will chop them up into small pieces while they’re being cut down by your lawn mower. 

On the other hand, if you don’t want clippings flying everywhere when trimming around objects like decks and fences then consider using an offset edge blade instead as these do not produce any discharge from where they’re attached on top off

lawnmower’s deck (which prevents damage caused by flying debris). Of course there are also several other options available such as power rotary blades which cut through tall weeds quickly without damaging landscaping around them (but usually require more maintenance).

“Pitchforks are a great alternative to aerate your lawn if you don’t have a lawn aerator. It’s an easy, cost-effective way to keep your lawn healthy and in great condition. Read our guide on can you aerate lawn with pitchfork to know more about how to proceed with lawn aeration.”

How Do I Install My New Lawn Mower Blade?

To change the blade in your mower:

  • Turn off the lawn mower and disconnect the spark plug wire.
  • Remove the blade from your mower by loosening or removing screws from both sides of it, depending on your model.
  • Install a new blade onto your machine by sliding it over those same screws that were removed to remove the old one (you may need to use a pair of pliers if they are too tight).
  • Reconnect your spark plug wire once you have finished installing your new blade and start up your mower again.

How Do I Take Care Of My New Lawn Mower Blade?

Keep the blade sharp. A dull blade will cause uneven cutting and leave grass clumps behind.

Clean the blade. After you’re finished mowing, remove any debris from the blade with a rag or brush.

Check the tension of your lawnmower’s blades by using an adjustable wrench or pliers to turn them counterclockwise until they are loose enough to rotate freely without resistance. If you can’t adjust them yourself, take your lawn mower to a repair shop for help.

Make sure there is enough oil in your machine; if there isn’t any left, add more before proceeding with step 5 below so that it doesn’t get too hot while operating again after adding new lubricant (if needed).

Check that there aren’t any bent parts on either side of each blade before reassembly takes place so nothing gets damaged during use later down road when everything starts moving around again due

“Wet grass, when not managed properly, can cause serious problems to your lawn mower, such as breaking or jamming the blade. To prevent this, learn from our experts in our guide on could wet grass break a lawn mower to ensure your lawn mower stays in great shape.”

Disassemble the lawnmower. This may be difficult depending on what kind of mower you have. If it’s a gas-powered model, make sure you turn off the fuel supply before removing any parts.

Remove the old blade and replace it with a new one (you’ll need one that matches your type of mower). 

Check that all bolts are secure before reassembling all components back into place again – they should fit snugly without excessive force being required so that they don’t fall out unless pushed too hard against what they’re holding together (careful not to strip threads!).

How Long Does It Take To Change A Blade On A Lawn Mower?

The time it takes to change a blade on your lawnmower will depend on the type of lawnmower you have. Some models are easier to access than others, and some require additional tools to remove or install blades. 

If you don’t feel confident doing this yourself or if you don’t have the right tools, it might be best to hire someone with experience changing out blades in various makes and models of lawnmowers.

What Tools Are Needed To Change A Blade In My Lawn Mower?

  • Socket wrench – a socket wrench is used to remove the bolt from the lawnmower’s engine case. This will allow you to take off the old blade and replace it with a new one.
  • Screwdriver – A screwdriver is used to remove bolts that hold on various parts of your lawnmower’s engine case. Without these bolts, you cannot take apart your mower to access its inner workings.
  • Hammer – A hammer can be used in place of a tool like an ice pick if necessary, but this should only be done when absolutely necessary because it can cause damage if not done correctly and will likely lead to more problems down the line (such as having issues with starting up).
  • Flathead screwdriver – A flathead screwdriver is needed because there are some screws that cannot be removed without one (or something similar).
