I bet you despise hearing bad news. especially when you’re in the middle of cutting the grass and suddenly notice your lawn mower blowing of white smoke; it’s understandable if you have a lot of questions, the most important being: is this a serious issue? Will this problem be an easy fix?

You need to relax and take a few deep breaths because we have a straightforward answer for you. It doesn’t make a difference whether you have a 2-stroke mower or a 4-stroke mower; you shouldn’t run the mower and start looking into the common reasons for this issue.

Common Causes Your Bad Boy Mower is Smoking

Bad boy mowers contain an internal combustion engine, which can have many problems, one of them being smoke emitting from the engine or muffler. There are several reasons this may happen:

• Air Filter is Plugged
• Insufficient Engine Oil Level
• Bad Gasket in Engine
• Internal Engine Damage

Insufficient Engine Oil Level in Your Bad Boy Lawn Mower

Not only is it crucial to ensure that your Bad Boy lawn mower has enough engine oil, but it’s also crucial to avoid overfilling it. Your engine may suffer severe impacts and start to smoke if either of these oil levels is too low. Clean the foam air filter element of a Bad Boy.

Your Bad Boy Mower’s Engine Oil Level Is Too Low

Running the mower with insufficient engine oil is one of the most frequent issues that might happen. Although it appears to be a little problem, your laptop could suffer significant damage.

The engine’s moving parts start to produce friction when insufficient oil is present. As a result of this heat buildup, the oil itself may eventually begin to burn. Additionally, the engine parts may start to melt, resulting in white or blue smoke from the exhaust. In some circumstances, the damage can be irreparable, necessitating a complete engine replacement.

It’s crucial to give your mower a thorough checkup, including checking the engine oil level, before each mow: Checking the oil level in your lawnmower takes a few minutes, but it could prevent you from having to make costly repairs later. Before each usage, make sure to check the oil and add extra if necessary.

It’s also crucial to pay attention to the oil’s color; if it begins to appear black or abrasive, it’s time for a replacement.

It’s best to identify this issue quickly and avoid operating your mower under these circumstances: As with most things, it’s considerably simpler (and less expensive) to remedy an issue as it first arises than it is once it has already caused significant harm.

If you have any reason to believe your mower might not have the recommended amount of oil, proceed with caution and wait to use it until you’ve checked (and potentially replaced) the oil.

You should send your lawnmower to a qualified small engine mechanic for analysis and repair if the level lowers quickly once more because there might be a leak somewhere in the system.

The Engine Oil Level in Your Bad Boy Mower Is Too High

Generally speaking, you should always check the oil level in your lawnmower’s engine before using it. However, a lot of individuals are unaware that using too much oil might lead to issues.

Too much oil in the crankcase increases the pressure, which can then push oil into the cylinder and even into the air intake through the valve train. Your lawnmower may sustain severe harm as a result, necessitating pricey repairs.

If you discover that your crankcase has too much oil, adjusting the quantity as quickly as possible is critical.

You can accomplish this by draining a little amount of oil through the oil filter or drain plug. A tiny amount of oil from the fill area can also be sucked out using an oil evacuator or turkey baster.

After removing some of the extra oil, check the level again with the dipstick and drain the oil as necessary until it is at the proper level.

It’s crucial to check your air filter to make sure it isn’t clogged with smoke or covered in grease. If so, swap it out for a fresh air filter to stop your lawnmower’s engine from suffering any more harm.

Bad Gasket in Your Bad Boy Mower Engine

If your mower’s gasket is damaged and engine oil leaks, it may be the cause of the smoke coming from your Bad Boy. A heated surface, such as your muffler, will burn off any excess oil that has spilt onto it and emit a lot of smoke.

Internal Engine Damage on Your Bad Boy Lawn Mower

Without disassembling the engine and carrying out leak down and compression checks, it might be challenging to pinpoint the precise cause of an internal engine issue.

However, there is a straightforward test you may perform to see if your internal engine is malfunctioning.

Remove your spark plug(s) and look for any evidence of oil to finish this inspection. Oil on the spark plug may indicate a piston ring or valve train issue. Even though this check is unable to diagnose your specific issue, it will let you know that a mechanic is required to fix it.

Taking your lawnmower to a small engine repair is crucial to assess the issue and determine the cause if you carry out this inspection and discover oil on your spark plugs. Ignoring an internal engine issue could cause major harm or possibly the engine’s demise.

Your Bad Boy Mower’s Piston Rings Have an Engine Problem

Your engine must be disassembled in order to detect a piston ring issue. Damaged piston rings or scoring is found inside the cylinder wall, oil could enter and burn off, which could cause your Bad Boy lawnmower to start smoking.

Your Bad Boy Mower’s Valve Train Has An Engine Problem

An overheated Bad Boy lawn mower can have a burned valve. Only the cylinder head may be removed and tested for leakdown, which is the only technique to detect burn valve problems.

This examination and repair should be done by a small engine mechanic. The technician must precisely cut the seat and the valve to finish the combustion chamber.

You Bad Boy Mower is Blowing Black, White or Blue Smoke: What’s the Difference?

I always advise using the aforementioned techniques to locate the source of smoke coming from your lawnmower. By examining the hue of the smoke, you might be able to determine most likely its source.

Blue or white smoke is frequently produced when burning excessive amounts of oil. Oil leakage from a harmed piston ring, the valve train, the combustion chamber, or an engine gasket might cause this.

A clogged air filter may potentially be the reason oil is being driven into the cylinder.

When changing the oil, don’t forget to look for oil burning off the muffler or engine as a result of an oil leak or spill.

Black Smoke: Black smoke is produced when fuel is burned too thoroughly. This happens as a result of a clogged air filter, which permits a higher fuel concentration in the fuel-to-air ratio.

The Bad Boy lawnmower can produce dark smoke when operating heavily. Check your mower for another air limitation if the filter is not the problem.

Conclusion

Mowing your lawn should be a relaxing and satisfying experience, but it can quickly become a nightmare if your lawn mower is blowing white, black or blue smoke. If you’re experiencing this problem, you can do a few things to diagnose and fix the issue.

First, check the oil level and grade to make sure that they’re correct for your model of mower. Next, inspect the air filter to see if it needs to be replaced.

Finally, take a look at the angle at which you’re mowing—mowers can start smoking when tilted at angles greater than 15 degrees.

If all else fails, remember that regularly conducting an oil change is one of the best ways to prevent smoking issues (and extend its life overall).

Common Engine Issues and Solutions for Lawn Mowers

A reliable lawn mower is essential to maintain a healthy, well-groomed lawn. However, like any mechanical device, lawn mowers can experience some issues that may hinder their performance. Continue reading to learn more about some of the most common lawn mower problems and practical solutions to fix or prevent them.

Why is my lawn mower smoking?

If you notice smoke coming from your lawn mower, it is typically a sign of an underlying issue. One common cause is an oil leak. Check the oil level and review the mower for any visible leaks.

If you find a leak, replace the damaged gasket or seal and ensure the oil is filled to the appropriate level. Smoking can also occur from an overfilled oil reservoir. If so, drain the excess oil and refill to the recommended level. A dirty or clogged air filter can also cause smoking. Remove the filter, clean or replace it if necessary, and ensure proper airflow to the engine.

Why did my lawn mower lose speed while running?

Losing speed while operating your lawn mower can be frustrating. One possible cause is a clogged or dirty air filter. Restricted airflow to the engine can result in decreased performance. Clean or replace the air filter regularly for optimal air intake.

If it is not an airflow problem, another cause could be a worn-out or loose drive belt. Inspect the drive belt for wear, such as cracks or fraying, and replace it, if necessary, as well as check the tension of the drive belt and adjust it as per the manufacturer’s guidelines.

A dirty or malfunctioning carburetor can also cause speed issues. Clean or repair the carburetor to restore proper fuel flow and maintain a consistent speed.

Why did my lawn mower lose power while mowing?

Losing power while mowing can be caused by a few different things. One common cause is a dirty or clogged fuel system. Debris and sediment can accumulate in the fuel tank, fuel lines, or carburetor, obstructing fuel flow over time. Clean the fuel system thoroughly, replace the fuel filter if necessary, and use fresh fuel.

A worn-out spark plug may also cause your lawn mower to lose power. Remove the spark plug and examine it for signs of fouling or damage. Clean or replace the spark plug as needed to ensure proper ignition.

Finally, check the mower’s blade for dullness or damage. Sharpen or replace the blade to maintain efficient cutting performance.

Why is my lawn mower making unusual noises?

Unusual noises coming from your lawn mower can indicate an underlying problem. A common culprit is a loose or damaged blade. Turn off the mower, disconnect the spark plug, and inspect the blades for looseness or damage. Tighten any loose bolts or replace the blade if necessary.

Another reason for unusual noises could be a faulty or worn-out engine component. Check the muffler, spark arrestor, or other engine parts for signs of damage or malfunction. Tighten any loose connections or replace damaged components as needed.

Additionally, inspect the mower for any foreign objects lodged in the cutting deck or other moving parts, as they can cause strange noises.

How can I prevent some of these common problems?

Routine service and maintenance are key to avoiding common lawn mower problems. A few tips to consider are:

• Regularly check and clean the air filter to ensure proper airflow.
• Keep the cutting deck clear of debris to prevent any impact to performance or unusual noises.
• Follow the manual recommendations for oil changes and use the correct type and grade of oil.
• Inspect and sharpen blades regularly for clean and efficient cuts.
• Replace the spark plugs according to manual recommendations.
• Clean the fuel system and use fresh fuel to prevent clogs and fuel-related issues.
• Store the mower in a clean, dry area, out of the weather elements.
• Use proper John Deere parts for your equipment.

Lawn Mower: White Smoke then Dies

Is a mysterious white smoke emerging from your lawn mower? If so, you’re probably worried and wondering what on earth is going on. If your lawn mower blows white smoke then dies, there’s even more cause for concern. In this article, you will learn about the potential causes of white smoke in a lawn mower, and what you can do to address the issue.

Let’s get started with your first burning question – is this serious and/or dangerous?

White Smoke Isn’t Always a Serious Problem

A bit of white smoke coming from a lawnmower is a common occurrence with many mowers. If you’ve been a homeowner for a while, you have probably experienced this at least once.

In many cases it is not a serious issue and this problem is easy to resolve, but in some cases may be serious. I’ll tell you about the likely causes, other potential causes, and how to address them below.

Your Lawn Mower Blows White Smoke Then Dies – Why?

If your lawn mower blows white smoke then dies, this is likely a result of oil getting into the machine’s carburetor. This typically means that the gas feed jet is blocked. In many cases, you will be able to fix this problem by continuing to run your engine until the oil is cleared, but if it’s impossible for you to run the engine for a long enough time, the carburetor probably requires cleaning.

How you clean your mower’s carburetor will depend on the type of mower you have, but if you’re handy at all it’s usually something you can do yourself. I have an article which will help you locate your lawn mower’s carburetor, and that article also provides some tips and resources for cleaning your carb, or replacing it with a new one.

Remember to carefully consult the manual that came with your mower (find it online if you no longer have a hard copy).

You should remove the plug and then try turning over the engine three times. This will help to remove the oil from the cylinder. After you’ve done that, clean and replace the plug. Use some carb cleaner spray like this one on Amazon (you can find these locally as well). Spray it right into the carburetor, replace your air filter, and then try to start the engine again.

If this doesn’t work, you will need to take out the carburetor and clean it.

Other Common Causes of Lawn Mower with White Smoke

Two of the most common causes of white smoke coming from a lawnmower are:

There are other more serious causes, such as a faulty crankcase breather or a head gasket failure, which I’ll go over below.

It’s also possible that your mower’s engine is simply worn out. But in most cases, adding too much gas or tipping your mower and getting gas where it isn’t supposed to be is what causes mowers to emit white smoke.

White Smoke and Burning Oil

White smoke often points to the problem of burning oil. This can manifest in a few different ways in your mower, and burning oil can be caused by the following problems:

• Using the wrong oil grades
• Too much oil in crankcase or exceeding the oil capacity of your engine (you should be able to tell this from the dipstick)
• Crankcase breather inoperative
• Air leak from crankcase
• Head gasket is blown
• Cylinder and/or rings are worn
• You turned or tilted the engine to the side for an oil change or storage (or another reason)
• The breather tube is obstructed (the breather tube is found behind the air filter)

When figuring out engine oil capacity, remember that the capacity depends on the specific kind of engine your mower has.

Check your lawn mower manual for more information, and if you don’t have the original manual, you can typically look it up and download it online by searching your mower’s name and model number plus “manual”.

Why is there White Smoke After Tilting or Flipping My Mower?

Many people will tilt or flip their mower to clean the mowing deck. This is especially true for self propelled and push mowers.

After tipping your mower to clean it, you may notice white smoke coming out of the machine. This happens because oil is able to get into the cylinder. This oil will then burn when you restart the mower, and this leads to the white smoke.

It’s also possible that oil could have spilled and come out of the muffler on your mower, which causes the same type of smoke.

If white smoke comes out of your mower and you recently tilted or flipped it for service, it’s likely a minor issue and the smoke will stop after it burns off. You can check to see whether the oil has made its way where it shouldn’t.

I recommend giving the machine time to idle until there is no more smoke prior to operation. The smoke should clear within about 10 minutes.

Lawnmower Smoke Due to Too Much Oil

If you have a riding mower like a lawn tractor and there is white smoke, this is usually an indication of excessive oil being added to the reservoir, or you may have a fault with the carburetor. It could also be a sign of a blown head gasket, but that is more rare.

Adding too much oil is one of the most common causes of white smoke, so ensure that you only put in what you need when changing the oil in your mower.

Most mower engines need just a little over half a quart to operate smoothly, which is less than you’d think. Accidentally overfilling is easy to do, so be careful when servicing your mower.

While you may believe that too much oil will simply burn off, an excessive amount of oil can actually damage your mower’s engine. Most engines have splash lubrication systems. As a result, if you use too much oil, its level will exceed the splash paddle. You will have problems (such as white smoke) when this happens.

It’s wasteful, and it isn’t great for your machine.

When this is the cause of the white smoke coming from your mower, you are seeing the result of the excess oil being burned. In order to resolve this problem, remove the excess oil and let the engine idle for about five minutes to burn off any excess that remains in parts of your engine it shouldn’t be.

Draining excess oil can be quite difficult for some kinds of mowers, but on walk-behind mowers it’s typically easy (tilt the mower and it drains out of the hole where you added it). If you own a riding mower, investing in a special oil extractor isn’t a bad idea. This one on Amazon runs about 25.

Failed Carburetor Seal

If you have an overfilled oil level and there is a gas smell, your mower may have a failed carburetor seal.

If you think this could be the case, you shouldn’t run the engine. This is because the oil is too thin for it to give your machine the protection it needs. Once you’ve repaired the carburetor, change the oil.

Find information on carburetor cleaning for your type of mower. These should include removing the carburetor, stripping it, cleaning it, and rebuilding it.

YouTube is a great resource for this, because it’s helpful to see the job done before you attempt it yourself.

Failed Head Gasket

While the white smoke coming from your mower probably isn’t caused by a failed head gasket, it’s still a possibility. If your mower has a failed head gasket, there will be an especially large amount of smoke.

The head gasket is made of graphite and metal. It is situated between the cylinder head and cylinder block of the engine. It is there to keep the combustion chamber sealed.

When a head gasket has failed, it can show itself with high crankcase pressures or oil leaks. There could also be a quiet puffing noise. This will be compression escaping from the cylinder. In this case, you will need to replace your head gasket.

White smoke can be caused by a blocked crankcase breather. This situation will also mean there is oil in the cylinder. To deal with this, you should clean out the breather pipe. If you find that you actually have failed or worn piston rings in the end, you will probably need a new engine. A new engine is usually the less expensive option when rebuilding is necessary. A new engine will also come with a guarantee.

Oil Accidentally in the Gas Tank

If there is white smoke coming from your mower, you have possibly put oil into the gas tank. This is quite a common problem. If you’ve done this and need to fix it, drain the gas tank and then put in fresh gas. You can use a siphon or fluid extractor (again, here’s a cheap one on Amazon) to make it easier if you like.

After you’ve cleared the contaminated fuel run the engine until the mower dies from lack of fuel. This should clear out the system so you can replace it with fresh gas.

If the engine still won’t start, you probably need to clean the carburetor.

Best of luck – I hope this article has helped you identify and resolve your mower problem!

Why Does My John Deere Smoke? [Causes Solutions]

You’re bound to get some anxiety when you notice smoke spewing from the exhaust or elsewhere on your expensive John Deere Mower. How bad is it? How much is it going to cost to get it fixed? Is the damage permanent? These are all reasonable questions, but there’s no reason to panic.

There are several potential causes behind smoke pouring out of your John Deere. Low coolant levels, low engine oil levels, too much oil, bad injectors, plugged air filters, and leaking head gaskets are some of the most common reasons for a smoking John Deere.

Fortunately, all of the above is repairable, and although a leaky head gasket sounds complicated, it’s not as bad as you think, and it’s also one of the rare causes on the list.

There are also cases where there may be white smoke, and nothing is wrong with your mower.

Potential Causes and Solutions

Nobody wants to see smoke spewing out of their lawnmower, especially if it’s a new John Deere, but it happens. So, the next step is ascertaining the problem. Where it’s coming from and how to fix it, hopefully on your own.

DIY repairs are the best way to go if you have the tools and capacity, especially when it comes to a John Deere because they don’t just hand out repairs for free.

However, if you have it under warranty, that’s a different story. Warranty or not, what could be the source of the smoke?

Low Coolant Level

Low coolant levels are easy to ascertain as you can simply check your coolant level and ensure that it is where it’s supposed to be. Of course, you want to let your mower cool down before you pop the cap.

When the coolant gets too low, overheating occurs throughout the engine, and while it won’t smoke like crazy, you will see some white smoke coming from the engine. If you own a relatively new John Deere, there’s a chance that you have low coolant because there is a slow leak somewhere.

You should top your coolant off, but you should check all of the connections in and around your radiator and observe it carefully while it is running.

Air Filter

There are three things required for combustion: air, fuel, and spark. If your engine isn’t getting enough air, then it is probably running “rich,” a term for too much fuel and not enough air for proper combustion. This will cause black smoke rather than white, and one of the first suspects is the air filter.

You should remove it and clean it thoroughly (use compresses air to blow it down if you can), but you should also include your air filter in your routine maintenance procedures.

Oil Level is Too High or Too Low

Lack of lubrication will certainly produce smoke, as you will have an increase in friction and heat from moving parts within the engine that are not properly lubricated.

The problem with low oil levels is that by the time you notice it (thanks to all of the smoke), there will likely be side effects throughout the engine.

Also, like the coolant levels, if your John Deere is relatively new or well taken care of, a low oil level is likely a sign of a leak somewhere.

Too much engine oil is nearly as problematic as the reverse. Excess oil burns off and increases pressure in the crankcase. The burning off creates smoke and, as a side effect, will damage or clog your air filter as well.

You’ll need to drain the oil and change or clean the air filter. Whenever you put oil in the mower, always use only the recommended oil type and the exact amount specified in the user manual.

Bad Injectors

If your injectors aren’t working correctly, you will not get the right amount of fuel. This usually leads to fuel that isn’t burned away and leftover fuel that isn’t ignited. The typical result is white smoke. However, the John Deere will also show signs of sluggishness, vibration, or otherwise just not running right.

Depending on what John Deere you have, the process for changing the fuel injectors can be drastically different. Fortunately, there are a lot of YouTube videos on the process. Also, if your John Deere is under warranty, you will want to take it in rather than risk voiding the warranty trying to repair it yourself.

There are also several fuel injector cleaners you can try first, as that might be enough to resolve the problem without having to get it repaired.

Leaky Head Gasket

If your John Deere is pretty new, a leaky head gasket is undoubtedly something that will be covered under warranty, so long as you haven’t done anything that would directly cause damage to a head gasket.

This is probably one of the more difficult things when it comes to a DIY fix, so if you are not a John Deere Tractor or Mower mechanic, it might save you a lot of headaches to just take it in for a repair.

It may be on the expensive side, but it’s not as bad as purchasing a new John Deere.

White Smoke, Black Smoke, and Blue Smoke

White, black, or blue smoke might not tell you exactly what the problem is, but they will point you in the right direction if you know what they mean.

Black Smoke

Black smoke is usually caused by burning too much fuel without enough air. Most of the time, that indicates bad injectors or, more commonly, a clogged-up air filter. If your air filter is relatively clean, there is an air restriction somewhere, which might be a problem with the choke.

Blue Smoke

Blue smoke is usually the direct result of burning oil. It’sIt’s just the color that tends to come from it when it is burning rather than lubricating the moving parts throughout your engine. Sometimes, the blue can be really dark, and that might mean that you have multiple issues going on.

If you see blue smoke, check your oil levels to ensure that the reservoir wasn’t overfilled during your last oil change or that there is plenty of oil there.

It’s mostly going to be a problem from excess oil. However, leaking oil can find its way into places hot enough to burn it off, and you’ll notice a low oil level.

White Smoke

You get white smoke from leaky head gaskets and gas in the oil or vice versa. Diesel engines are more prone to white smoke, but that doesn’t mean you will never see it in gasoline engines.

Diesel fuel filters that aren’t working properly can cause white smoke, and out of three colors of smoke, this one will be the most prevalent, especially in diesel engines.

Conclusion

Signs of smoke emanating from your John Deere aren’t the end of the world. However, there is always cause for concern.

The best thing to do is address the smoke immediately and locate the cause, even if you discover that the cause is nothing damaging.
