As a Bad Boy lawn mower owner, it’s important to know how to change the blades on your mower. This helps ensure you always have a nice sharp cut and prevents brown tips on your grass from dull edges.

Here are some easy steps to follow when changing blades on Bad Boy mowers.

How To Start Changing Blades On A Bad Boy Mower

If you own a Bad Boy lawn mower, it’s important to know how to change the blades. Over time, the blades can become dull or damaged and need to be replaced to keep your lawn looking its best.

This process is not difficult, but there are a few things you’ll need to gather first, including new blades and some basic tools. Follow the steps below and you’ll have new blades on your mower in no time!

To stop the lawn mower from moving while you work, be sure to engage the brake and use wheel chocks on both sides of the wheels.

Remove the blade bolts

To remove the blade bolts, you’ll need a socket wrench. If the blades are still mounted to the deck housing, place a block of wood between the deck housing and the blade to stop it from rotating while you use the socket wrench to remove any mounting hardware, such as bolts and washers.

Take care not to lose any components in the process. Once all of the hardware is removed, you should be able to take off the blades by hand easily.

Remove your Bad Boy mower blades

When you remove the blade, you should be aware of its location. The blade’s sharp edge on the new one may be mounted in the same direction, often with the assembly being turned counterclockwise. Pay close attention to how this blade is placed, then replace the new edge appropriately.

Install Your Bad Boy Mower Blades

The majority of mower designs forbid installing the mower blade with the wrong side down. Majority of blades has a retaining plate that prevents the blade from being installed anywhere other than the proper location. However, mower blades can be installed improperly.

Additionally, a blade can occasionally be installed too loosely. A poor installation will become apparent very quickly due to vibration and subpar lawn cutting performance; in contrast, a properly fitted installation should go unnoticed by users until it is time for maintenance or replacement again.

Clean area under your deck

A clean area under your deck is important for several reasons. First, it helps the new blades to be properly balanced when installed. Second, it keeps old blades from becoming dull too quickly.

Third, it makes it easier to see any potential problems with the deck itself. Finally, fourth, and most importantly – a clean area under your deck simply looks nicer!

Use a putty knife or other tool to scrape away any debris that has built up over time; then sweep or vacuum up the loose dirt and dust before proceeding with installing new blades or sharpening old ones.

Install blades

When it comes to installing blades, there are a few things you need to keep in mind. First and foremost, be sure that the area you’re working in is clean and free of dust or debris.

Old blades can often times be sharp, so it’s important to take care when handling them. Newer blades should also be inspected for any potential problems before installation.

The blade must be installed correctly; they can fit upside down. The center will be located higher than the edge’s ends if the edge has an offset. To avoid damage when the nut securely tightening, you must ensure that the blade fits onto the spline.

Tighten the bolts using a torque wrench

Tightening the bolts on your lawn mower is important to maintaining its edge and preventing injury. Use a torque wrench to properly tighten the bolts, following the manufacturer’s specifications detailed in your owner’s manual.

Be especially careful when tightening the bladebolt – use a block of wood to help prevent it from turning as you twist the nut tight. Inspect other parts of your mower, like belts and pulleys, before each use to make sure everything is functioning correctly.

How to Sharpen Your Bad Boy Blade DIY

If you own a Bad Boy lawn mower, you know that the blades need to be regularly sharpened to keep the grass looking neat and tidy.

However, taking your mower into a professional shop can be expensive, so why not sharpen the blades yourself? With a little time and effort, it’s easy to do-it-yourself. Plus, doing it yourself will save you money in the long run.

Gather the tools you will need

First of all, make sure that you have all of the necessary materials before starting. You’ll need a blade grinder (which can be found at most hardware stores), gloves, safety glasses, and a new or very sharp file.

It’s also important to note that there are different Bad Boy Lawn Mowers, so make sure you’re using the right blade type for your model!

The wire brush is the best way to clean bad boy blade of dirt and stubborn areas of buildup. Just put on your safety eyewear and work gloves, then begin scrubbing the grime off with the rag. For particularly difficult accumulation, use a wire brush.

Secure Your Bad Boy Mower Blade

Bad Boy mower blades need to be sharpened regularly to maintain effectiveness. This is an important step in keeping your lawn looking its best.

When sharpeniing the blade, it is important to have a secure workspace with good lighting and no cords in the way that could pose a tripping hazard. The Bad Boy blade must be securely fastened in a vice so that it does not move during the honing process.

Once one side of the blade has been sharpened, it should then be flipped over and secured again beforesharpeningthe other side.

File or Grind Bad Boy Blade Edge to Sharpen

When sharpening a blade with a file, it’s important to use the right angle and direction. Hold the file at an angle to the blade and push it along in one direction only.

Avoid sawing motions, which will damage the file. After getting rid of all burrs and jagged edges, flip the blade over and sharpen the other side. Clamp the blade in a vice when doing this so you can work safely.

A drill powered blade sharpener can be used to sharpen a blade edge quickly and easily. To use the sharpener, simply move it up and down along the length of the blade edge.

Once one side has been properly honed without any rough edges or nicks, flip the blade over and secure it in a vice before repeating the process on the other side.

An angle grinder is a great tool to use for sharpening a blade. The blades on most tools get dull over time and will need to be replaced or sharpened. An angle grinder can be used to sharpen the blade by running it along the edge of the blade until all of the rough spots or nicks are gone.

It is important that you hold the angle grinder parallel to the edge of the blade so that you do not remove too much metal from one side.

You should also flip the blade over and secure it in a vice beforeSharpen with an Angle Grinder beginning to sharpen so that you can work on both sides evenly.

How to Balance Your Bad Boy Mower Blade

Before reinstalling your mower blades on your Bad Boy mower, they must be balanced. If you don’t, your crankshaft may vibrate and become damaged. A blade is said to be balanced when each side of it is equally weighed.

Check the balance of your blade using a blade balancer or by following these instructions:

If you don’t have a blade balancer, you can hammer a nail about 3/4 to 1 inch away from the wall into the wall. The blade’s center should be on the nail head with the point facing up.

The hung weight should match on both sides before trimming any more metal off of the lower hanging side until it balances with equal weights

When Should You Seek a Professional Sharpening Service for Your Bad Boy Blade?

If you’re not entirely confident in your ability to balance or sharpen a blade, you should seek professional assistance.

Your crankshaft or engine could sustain more harm if your blades are not balanced properly or are still worn from use. Even though I have the equipment to sharpen my own mower blades, I personally prefer to have them done by my neighborhood lawn mower dealer.

They simply give the blade a nicer, cleaner edge than I can get cutting it myself. Trust us – an injured person AND broken equipment is NOT what we’re going for here!

  • It is a far more prudent choice than sharpening the blade on your own.
  • In many cases, the cost of sharpening a blade is lower than the cost of acquiring a new blade.
  • A skilled specialist can remove big nicks and gouges in the steel blade of a mower by grinding it down. This ensures that the blade is correctly balanced. Because of this, your mower’s vibration and wear and tear will be reduced.


As you can see, it is relatively easy to change your Bad Boy mower blades yourself with just a few tools and safety precautions.

Not only does this save you time and money, but it also gives you the opportunity to be sure that the job is done correctly.

Be sure to consult your owner’s manual for manufacturer recommendations specific to your model before beginning any repair project on your lawn mower.

Do I Need To Change My Lawnmower Blades?

Here’s a quick and easy guide to the three basic blade types, and how to keep your mower cutting right.

By Roy Berendsohn Published: Jan 22, 2019

changing, blades, mower, quick

If you want to make your life a lot easier this spring and summer, buy a spare blade for your walk mower. Here’s why.

Know the Types of Blades

Broadly speaking, blades are designed to bag, discharge or mulch. No single blade can do all of those perfectly, but manufacturers have developed combination blades that do two out of the three pretty well. So when you buy a blade, pay attention to the manufacturer’s specs. For example, If most of your mowing is mulching, but you rarely bag, buy a mulching blade or a combo mulch/bagger.

Why You Should Keep Spare Blades Around

The wear and tear on a blade is considerable and if all you have is a single blade, you’ll probably find yourself running a dull blade. It’s human nature. You’ve got a lawn to mow and other work (or fun things) to do, so it’s only natural to put off sharpening. But changing out a sharp blade is pretty simple and only takes a few minutes. Then you can sharpen the dull blade when you get a few minutes.

From Popular Mechanics

The hits just keep on coming. I patrol grass before I mow it to clear the area of rocks and garbage and I still hit stuff. Once, somebody threw a Coke bottle that bounced its way under the edge of a shrub. I never saw the bottle but I heard it, as soon as the blade sucked it up. That blade was toast.

Stay sharp. Having a spare means a sharp blade on hand and ready to go at a moment’s notice. This way you can cut grass for a few weeks and then swap the blade when you have a few spare minutes. Save the chore of blade filing or sharpening for a rainy afternoon or an evening.

Spread out the wear. Having spare, sharp blades allows you to distribute the wear. That way you’re not working one mower blade to death. And a sharp, well-balanced blade is easier on your mower because the mower doesn’t have to work as hard if the blade is sharp.

Your grass will thank you. A sharp blade is a simple thing you can do to improve grass health. Grass losses less moisture through a neatly-cut leaf as opposed to one with a ragged tip. Also a spare dedicated mulching blade will contribute to lawn health by contributing to maximum mulch action and deposit.

Come fall, you’ll thank us. Why? If you get a combination blade or a dedicated bagging blade, you’ll be able to better pick up leaves with your mower. Conversely, a dedicated mulching blade helps mulch leaves into your lawn.

A Word About Sharpening

Most of the time, all you need to sharpen a blade is to refresh its edge with a file and then suspend it from its center on a nail driven into the edge of your work bench or a wall stud to check it for balance. A blade that’s been damaged can be sharpened on a bench grinder or with a right-angle grinder. This requires a bit of practice, so that you don’t remove too much steel.

A file like this is all you need:

How Often Do I Need to Replace My Lawn Mower Blades?

How often you change or sharpen your lawn mower blade depends on the type of grass you have, size of your yard and how often you use your mower. For a typical homeowner, every couple of months the blade will need sharpened, or even once a month if you mow more than once/week.

Three Things to Look for:

Unevenness. Does your yard grass length look uneven after you mow? You may need to change out your blades or get them sharpened. When your blade is sharp, your grass will be cut at the same height every time with just one pass. If you’re making multiple passes to even out your yard, it may be due to a dull blade.

Torn or Non-Cleanly Sliced Grass. Take an up-close look at your grass. If you notice that the tips of your grass blades are torn and/or not cleanly slicked, it may be time to switch out your blades. Furthermore, ripped and damaged grass will lead to decreased grass health, causing grass to lose its lush, green color.

Look at the Blade Itself. Look for large chips or dents in the cutting edge that can’t be smoothed out. Over time, sand, dirt and other yard debris can erode your blade, causing the metal to weaken and even become paper-thin.

How to Remove Riding Lawn mower Blade?

changing, blades, mower, quick

Riding Lawn mowers can make the chore of mowing a large lawn so much easier. Rather than push an electric cordless Lawn mower around your yard, you simply sit on top and whizz around until the job is done.

For speed and effortlessness, a riding Lawn mower is even better than using a self propelled Lawn mower, but you still need to keep it properly maintained.

One of the most important aspects of looking after your riding Lawn mower is keeping the blade sharp. A dull blade tears rather than cuts the grass, and this will damage your lawn.

However, these mowers are large and heavy pieces of machinery, and this kind of task is not always easy – so here’s a step-by-step guide for how to remove riding Lawn mower blade.

Safety first

changing, blades, mower, quick

A riding Lawn mower has a large blade that can be extremely dangerous if activated by accident when you are doing maintenance work. For this reason, safety should always be your primary concern.

First of all, make sure you are wearing thick gardening gloves – this will prevent you from cutting your hands on the blades – and that you find a flat, hard surface in a well-ventilated area to work on.

Start by ensuring the parking brake is engaged. You don’t want your mower rolling onto you while you are working underneath it.

Next, remove the ignition key and remove the battery or spark plug. This way, there is no chance of the blades starting up unexpectedly and potentially causing a serious injury.

You are now ready to start work.

Lift the front of the mower

changing, blades, mower, quick

To gain access to the underneath part of the mower, you will need something to lift it. Possibly a regular car jack could be used or even a suitably-sized log, but it is better if you have a specialist device for your Lawn mower.

In, any case, you need to raise the front of the mower into the air to allow you to reach the blade underneath.

Use a block of wood to stop the blades from turning

You need to make sure the blades are immobile when you come to unscrew the bolt. The best way to do this is to wedge a block of wood into the blades in such a way as to stop them from turning as you turn the bolt.

Take a photo of the blade configuration

Mower blades can be very easy to reattach the wrong way around, and once you’ve removed them, it might not be completely obvious which way you should put them back in.

A good way to make sure you will be able to put everything back in place correctly is to use your cell phone to take a photo before you start doing the work.

Take a photo that shows which way the blades are installed – and then you’re ready to start removing the blades.

Here’s a video that explains how it can all go wrong – and how to avoid this issue.

Unscrew the nut or bolt

Using a correctly-sized wrench, unscrew the nut or the bolt that holds the blade in place by turning it counter-clockwise. Place the nut or bolt somewhere safe where you will be able to find it again and then remove the blade.

Sharpen or replace the blade

changing, blades, mower, quick

Once removed, you can set about sharpening the blade. However, if the blade is very old, very dull or is chipped or damaged, it may be better to simply replace it with a new one.

If you decide to replace it, take the old one with you to the hardware store to compare with the new one. There are many brands of riding mowers and all use different parts – by taking the blade with you, you can ensure the new one is compatible with your machine.

Carry out any other maintenance work

While your mower is in the air, this is a good time to check any other issues that might need to be addressed. At the very least, you can make sure there are no grass clippings or other debris stuck underneath and making it hard for the blades to turn.

You can also take advantage of the opportunity to make sure that the relevant moving parts are well oiled.

Refit sharpened blade or fit new blade

changing, blades, mower, quick

This is where the photo you took earlier comes in useful. Checking the photo, reattach the blade, taking care to fit it the right way.

You can use the same technique as before with the piece of wood to block the blades while you tighten the nut or bolt. With the wood in place, tighten the blades with the wrench, this time turning in a clockwise direction.

Lower the mower and reattach battery or spark plug

When the blade is fitted back into place, carefully lower the mower back down to ground level. Refit the spark plug or battery as necessary and you’re almost ready to go.

Check oil and fuel

changing, blades, mower, quick

An optional final step is to check the oil and fuel at this point. While not technically part of changing the blade, this is simply a good habit to develop as it will help ensure you always have enough oil to protect the engine – and that you won’t run out of fuel when mowing.

When should you sharpen or change your blade?

It is a good idea to give your mower a full service each year in the early spring before the growing and mowing season begins, and checking and sharpening the blades should be a part of this.

Unless you use your mower very intensively during the mowing season, you shouldn’t need to sharpen them more than once a season – although it doesn’t hurt to check them after the first three months of mowing.

Normally, sharpening blades will keep them cutting efficiently – but when they become older and start to have lots of nicks and chips in the blade, it might be time to consider buying a new one.

Keep blades sharp for optimum cutting performance

Keeping your mower blades sharp will enable you to achieve a clean cut when you mow the lawn – this is more efficient and is also much better for the grass since a dull blade will tear and damage the blades of grass. Whenever working on your mower for maintenance, always consider safety first to help avoid any serious injuries.
