Snapper lawnmowers smoke if there is not enough engine oil in the engine, a plugged air filter, or a faulty engine gasket.

There is a possibility of smoking due to a problem with the valve train or piston rings of the engine. A Snapper mower that burns a high concentration of fuel can also emit smoke.

Is your lawnmower on its last legs? Your lawnmower emits different colors of smoke, and you can’t figure out what they all mean! Described below are the different colors of smoke and how to fix it on your own or by a professional Why Your Snapper Lawn Mower is Smoking.

Regardless of the color, smoke from your lawnmower is cause for concern and may require professional assistance. In a more positive light, blowing smoke does not necessarily indicate serious problems with your lawnmower, but it can become one if left unattended. 

Reasons Your Snapper Mower is Smoking

Why Your Snapper Lawn Mower is Smoking

There is a high probability that the engine in your lawn mower is burning oil if you see it blowing white or blue smoke. Here are some things that could cause your engine to burn oil (from most common to least common):

• A lawn mower was tilted incorrectly on its side, or it was used at an excessive angle.
• A lawn mower was lubricated with too much engine oil.
• Oil has been found in the lawn mower’s fuel.
• Head gaskets, piston rings, or cylinders with damage/malfunctions.

To determine which cause(s) may apply to you and your lawn mower, let me describe each one in more detail.

Your Snapper mower’s engine oil is too low

The internal engine parts will not be lubricated properly if your engine oil is low. Your engine gets hot when there isn’t enough oil, causing friction to build up. As a result of the heat, the oil becomes flammable and parts of the engine may melt. Smoke is produced as a result.

The oil in your mower engine may be low, causing you to experience smoke. You can try adding fresh oil and operating your mower again.

Despite correcting the engine oil level, if your mower became hot and began smoking because of low oil, you probably caused engine damage that cannot be repaired.

If you are having problems with your mower, you should take it to an experienced small engine mechanic.

You should check the engine oil level of your mower before each mow. A low level of engine oil can damage your mower Why Your Snapper Lawn Mower is Smoking.

You should catch this problem early and avoid running your mower under these conditions.

Why Is My Snapper Mower Blowing Blue, White, or Black Smoke?

Whenever you smell smoke coming from your mower, I recommend following these steps to identify its source. Identifying the color of the smoke, however, may be an indication of its possible cause.

It is associated with the burning of excess oil and blue or white smoke appears. Several things can cause this, including damaged piston rings, valve train damage, or engine gasket leaks. A plugged air filter can also cause oil to be pushed into the cylinder.

Excessive fuel combustion causes black smoke. Fuel concentration is higher due to a plugged air filter allowing fuel to be more concentrated.

There is a possibility that the Snapper mower will emit black smoke when it runs rich. In the absence of an air filter, look for another air restriction in the mower.

The meaning of white lawn mower smoke?

In most cases, lawn mower smoke is white, and it fades away by itself. In the event it does not, you have an overflowing oil reservoir. It can be caused by a variety of factors, but overfilled oil reservoirs will cause an engine to burn oil. 

Among these are spilling oil on the housing or overfilling the crankcase while servicing the lawn mower. 

If you mow on a 15-degree incline, overfill the gas tank if it’s a 2-stroke mower (the correct ratio is 32:1 gasoline to oil), or if it’s a recently purchased mower with leftover oil residue, the lawn mower oil reservoir can fill up over time. 

White smoke will disappear on its own if you leave the lawn mower running for a few minutes since exercise will burn off excess oil. The white smoke may not dissipate after you run your lawnmower for roughly 15 minutes.

The first issue is that the seals on the combustion chamber may have worn out, causing oil to leak into it. There may also be an air leak in the crankcase, or both the rings and the cylinder are worn out. 

It is more than likely that white lawn mower smoke is caused by a malfunctioning head gasket, which will require professional care. Check if your lawn mower is still under warranty, and if so, bring it to your nearest service dealer for an inspection. 

What causes a lawn mower to smoke?

 It is probable that your smoke problems are caused by leaky oil seals in the engine’s lubrication system or around the pistons. Your crankcase is also cracked. These are jobs that should be left to a small engine pro unless you’re experienced working on engines. Alternatively, you may need to clean or adjust the carburetor if smoke is being produced. Almost all owners’ manuals include instructions for adjusting carburetors.

Blue smoke is coming out of my lawn mower. What does it mean?

There are pretty much the same reasons why blue smoke emits from your lawn mower exhaust as white smoke. In addition, it is possible to overfill the crankcase or spill oil on other parts of the mower when filling the crankcase. 

It is also possible to cause blue smoke with incorrect oil grades or when tilting the lawn mower too much when mowing a ditch or hill. Therefore, ensure the spark plug is tilted when mowing an angled area.
