When you start up your lawn mower, you expect it to produce green grass, not white smoke. So Why Would a Lawn Mower Blow White Smoke? There are several reasons this could happen, and some of them are serious.
If you see white smoke coming from your lawn mower, don’t ignore it. Gardenssay detailed here what you need to know about why it’s happening and what you can do about it.
White Smoke Coming From Lawn Mower – How To Fix It
Why Would a Lawn Mower Blow White Smoke – Here Is Why
If your lawn mower is blowing white smoke, it could be due to a variety of reasons. The most common reason is that the engine is burning oil.
This can happen for a number of reasons, such as if the oil level is too low or if the oil isn’t being changed frequently enough.
Another possibility is that there’s water in the fuel.
This can happen if the fuel has been sitting for a while or if it was exposed to moisture somehow. Either way, it’s not good for the engine and will likely result in white smoke.
If your lawn mower is blowing white smoke, try troubleshooting these possible causes before taking it to a mechanic. Also, read Why Would a Lawn Mower Stop Running & Lawn Mower Runs for 30 Minutes Then Dies.
Why Does My Lawn Mower Blow White Smoke When I Start It
If your lawn mower blows white smoke when you start it, there are a few possible causes. It could be caused by too much oil in the engine, a dirty air filter, or a problem with the carburetor. If there’s too much oil in the engine, it can cause the engine to overheat and produce white smoke.
To fix this, you’ll need to drain some of the oil from the engine. If the air filter is dirty, it can restrict airflow to the engine and cause it to run lean. This can also lead to white smoke coming from the exhaust.
Cleaning or replacing the air filter should fix this problem. Eventually, if there’s an issue with the carburetor, it can cause fuel to be drawn into the engine without being properly combusted.
This will also result in white smoke coming from the exhaust. You may need to adjust or clean your carburetor to fix this issue.
Lawn Mower White Smoke Then Dies
White smoke from a lawn mower engine is typically caused by too much oil in the crankcase. This happens when the oil level is overfilled, or when the wrong type of oil is used.
If too much oil gets into the combustion chamber, it can cause the engine to “hydrolock,” which means that the piston can’t move up and down properly.
This will cause the engine to stall and produce white smoke. If your lawn mower’s engine produces white smoke and then dies, first check the oil level. If it’s overfull, drain some out until it reaches the full line on the dipstick.
If you’re using the wrong type of oil, switch to a higher-quality lawn mower oil recommended for your model. Also, if your lawn mower has been sitting for a while without being used, make sure to add fresh gas before starting it up again.
Lawn Mower White Smoke Fix
If you’re like most people, you love the smell of freshly cut grass. But if your lawn mower is producing white smoke, it’s not exactly an aromatherapy session. White smoke coming from a lawn mower usually indicates that oil is burning in the engine.
While this may seem like a big problem, it’s actually pretty easy to fix. The first thing you need to do is check the oil level in the engine. If the oil is too low, it can cause white smoke.
To top off the oil, remove the dipstick and add more oil until it reaches the “full” line on the dipstick. Once you’ve topped off the oil, replace the dipstick and start up your lawn mower again. If it’s still producing white smoke, move on to step two.
Step two is to clean or replace the air filter. A dirty or clogged air filter can restrict airflow to the engine, causing it to overheat and produce white smoke. To clean your air filter, simply remove it from its housing and rinse with warm soapy water (be sure to let it dry completely before putting it back).
If your air filter looks damaged or excessively dirty, play it safe and replace with a new one – they’re relatively inexpensive and easy to find at any hardware store or home center.
Assuming steps one and two don’t solve your problem, there’s a good chance that something is wrong with your carburetor – specifically, that there’s too much fuel mixture going into the engine cylinders (this is known as “flooding”).
This can happen for a number of reasons – old gas sitting in the tank over winter months being one of them. The easiest way to fix this problem is to drain all of the gas from your tank and then refill with fresh gas (adding a fuel stabilizer wouldn’t hurt either).
Is White Smoke from Lawn Mower Dangerous
It’s a common misconception that white smoke coming from your lawn mower is dangerous. However, this isn’t necessarily the case. While it’s true that white smoke can be indicative of engine problems, it doesn’t necessarily mean that your engine is in danger of overheating or catching fire.
In most cases, white smoke is simply the result of burned oil and is nothing to worry about. If you do notice white smoke coming from your lawn mower, it’s important to take a look at the oil level before taking any further action.
If the oil level is low, topping it off may solve the problem. However, if the oil level is already full, then there may be an issue with the engine itself and you’ll need to take it to a mechanic for further diagnosis.
Lawn Mower White Smoke And Sputtering
If your lawn mower is sputtering and emitting white smoke, there are a few possible causes. It could be that the oil level in the engine is too low, or that the air filter is dirty and needs to be replaced. Another possibility is that the spark plug isn’t firing properly.
Whatever the cause, it’s important to diagnose and fix the problem as soon as possible, as continuing to operate a lawn mower with these issues can cause serious damage to the engine.
If you’re not sure what’s causing your lawn mower to sputter and emit white smoke, take it to a qualified repair shop for diagnosis and repairs. In the meantime, here are a few things you can check on your own-
Oil Level – Check the oil level in your lawn mower’s engine according to the manufacturer’s instructions. If it’s low, add more oil until it reaches the proper level. Be sure to use the type of oil specified by the manufacturer- using a different type of oil can cause problems.
Air Filter – A dirty air filter can restrict airflow to the engine, causing it to run less efficiently and potentially overheat. Inspect your air filter and clean or replace it if necessary. Consult your owner’s manual for specific instructions on how to do this.
Spark Plug – A faulty spark plug can prevent ignition from occurring in an engine cylinder, which will cause that cylinder not to fire properly. Remove the spark plug and check it- if it looks damaged or fouled, replace it with a new one.
Again, consult your owner’s manual for specific instructions on how best to do this.
Riding Mower Blowing White Smoke When Blades are Engaged
If you’re riding mower is blowing white smoke when the blades are engaged, there’s a good chance that the engine is burning oil. This is usually caused by worn piston rings or valves, and it can be fixed by replacing those parts.
In some cases, though, the damage may be too great and the engine will need to be replaced.
Lawn Mower Blowing Blue Smoke
If your lawn mower is blowing blue smoke, it could be a sign of a serious problem. Blue smoke from a lawn mower typically indicates that oil is being burned along with the fuel. This can damage the engine and cause other problems.
There are several possible causes of blue smoke from a lawn mower. One is that the oil level in the engine is too high. When this happens, the excess oil can be drawn into the combustion chamber and burned along with the fuel.
This will cause blue smoke and can damage the engine over time. Another possibility is that the oil seals or gaskets in the engine are worn out or damaged. This can allow oil to leak into the combustion chamber and be burned along with the fuel, causing blue smoke.
Worn out seals and gaskets should be replaced as soon as possible to avoid further damage to the engine. A third possibility is that something else is wrong with the engine itself, such as a cracked cylinder head or piston rings.
These problems can also cause blue smoke due to oil being drawn into the combustion chamber and burned along with the fuel. If you suspect any of these problems, it’s best to take your lawn mower to a qualified repair shop for diagnosis and repairs.
Lawn Mower Blowing Black Smoke
If you notice your lawn mower blowing black smoke, it’s important to take action quickly. Black smoke coming from a lawn mower is an indication that the engine is not running properly and needs to be fixed.
There are a few things that can cause a lawn mower to blow black smoke.
One possibility is that the air filter is dirty and needs to be replaced. Another possibility is that the fuel mixture is too rich, meaning there’s too much oil in the mix. This can happen if you accidentally put too much oil in when filling up your gas tank.
Too much oil in the mix will cause the engine to run less efficiently and produce more smoke.
If you notice your lawn mower blowing black smoke, make sure to take action right away so you can get it fixed and back up and running smoothly again.

How Do I Fix White Smoke on My Lawn Mower?
If your lawn mower is emitting white smoke, there are a few potential causes. The most common cause of white smoke is an issue with the engine’s oil. If the oil isn’t changed frequently enough, it can break down and start to burn.
This will cause white smoke to come out of the exhaust. Another potential cause of white smoke is a problem with the fuel mixture. If too much oil is mixed with gasoline, it can cause the fuel to burn inefficiently and produce white smoke.
If you’re not sure what’s causing the white smoke, take your lawn mower to a qualified repair shop for diagnosis and repairs.
Why is My Lawn Mower Blowing Out White Smoke?
If your lawn mower is blowing out white smoke, it could be due to a variety of reasons. First, check the oil level. If the oil is low, it can cause the engine to overheat and produce white smoke.
Also, make sure that the air filter is clean. A dirty air filter can also cause the engine to overheat and produce white smoke. Eventually, if the gas tank is empty or nearly empty, this can also cause the engine to overheat and produce white smoke.
How Do I Fix My Smoking Lawn Mower?
If your lawn mower is smoking, there are a few possible causes. The most common cause of the smoke is oil leaking onto the hot engine. This can happen if the oil level is too high, or if the oil seal is damaged.
Another possible cause of the smoke is fuel leaking into the hot engine. This can happen if the fuel line is damaged or clogged. If your lawn mower is smoking, you should first check the oil level and make sure it’s not overfilled.
If the oil level is fine, then check for leaks from the oil seal or fuel line. If you find a leak, you should repair it before using the lawn mower again.
How Do I Fix White Smoke from Exhaust?
Assuming you are referring to a car: If you see white smoke coming from your exhaust, it could mean that your engine is burning coolant.
Coolant is usually a bright green or yellow color, so if you see white smoke and notice that your coolant level has decreased, then that is likely the issue.
To fix this, you will need to locate the leak in your cooling system and repair or replace the damaged component. Once the leak has been fixed, be sure to refill your coolant reservoir and keep an eye on it to make sure it doesn’t happen again.
If you continue to see white smoke after repairing the leak, then there may be another issue with your engine and you should take it to a mechanic for further diagnosis.
Conclusion
If your lawn mower is blowing white smoke, there are a few potential causes. The most common cause is that the engine is running too rich, meaning that there is too much fuel being burned. This can be caused by a number of things, including a dirty air filter or carburetor, an incorrect spark plug gap, or an oversize piston.
Another potential cause of white smoke from a lawn mower is water getting into the cylinder. This can happen if the engine gets too hot and the coolant system isn’t working properly. Lastly, white smoke can also be caused by oil leaking into the cylinder.
