Reasons Why Your Riding Lawn Mower Smokes

Why Your Kubota Lawn Mower is Smoking

Clean air is essential for the performance of your Kubota mower. Having a plugged air filter can cause it to run rich and emit black smoke when it lacks sufficient airflow. When the ratio of fuel to air is larger than air, this is known as running rich.

Smoke can also result from a blocked air filter, which prevents the engine from drawing air through the intake. Wherever air is available to it, it will find it.

This can result in air being pulled from the engine crankcase. Using air, oil can be pulled into the cylinder. As the oil burns, smoke is produced.

You can clean your riding mower’s air filter by following these steps:

• Take out the air filter from the housing.
• If any dirt remains in the housing, remove it with a clean, dry cloth. Avoid allowing dirt to fall into the air intake.
• The dirt in your air filter should be loosened and knocked away by tapping it against a solid surface.
• The filter should reflect light if held up to a light source. Whenever you can see light, repurpose your paper; when you cannot, replace it with a new filter.
• You should never run your riding mower without an air filter, even if it’s a temporary fix. Any debris or dirt that enters the engine could damage it. Repair costs can be high as a result.

It’s time to check the oil level in your Kubota mower

In the presence of insufficient oil in the engine crankcase, friction can build between moving parts of the engine.

Friction can increase the heat so much that the components can melt and the oil can begin to burn off, causing smoke. If you attempt to fix the problem by increasing or decreasing the oil level, it is most likely not enough to help.

Low oil suddenly causes your engine to smoke, which can result in severe engine damage and an expensive repair bill.

Checking the engine oil level before every mow is a necessity, not just a suggestion. In this way, you’ll be able to catch problems early on. In the event that your mower’s engine oil level is low, it could indicate you have an oil leak or that you are burning or consuming oil.

In the case of a low engine oil level, you should check your engine for leaks and repair them. If you can’t find the cause of your low oil level, have your engine checked out by a small engine mechanic who is experienced.

Before continuing to run your Kubota lawn mower, the mechanic can perform some tests to determine what the problem is.

The engine oil level is too low on the riding mower

The parts of your engine don’t receive adequate lubrication when there isn’t enough oil in the crankcase. Lack of lubrication can increase friction, resulting in an increase in heat generation.

When the heat becomes so intense, the parts melt and the oil burns off, creating smoke.

A low oil level and high temperature in your engine can be detrimental. Added oil could bring it up to the correct level, but it is unlikely to work.

When you run out of oil and the oil starts smoking, you have already suffered significant interdamadamage. A qualified engine mechanic can diagnose the extent of the damage.

Kubota mower engine oil is full

If you have too much oil in your engine, pressure can build inside the crankcase. As a result of this pressure, the oil will enter your cylinder and meet the air intake through the valve train. During combustion, oil burns off and creates smoke.

Smoke can cause your air filter to clog. It is also possible to cover the filter with oil when oil is pushed through the air intake. Once you find oil stains or a plugged filter, you should replace it.

You should adjust your engine oil level to the manufacturer’s recommendation. A dipstick indicates the full level of oil in your engine by two lines.

If your Kubota’s drain plug or oil filter has an oil drain hole, drain a bit of oil from them. A turkey baster or an evacuator can also be used to remove oil from the oil fill area.

You should always check the engine oil level and drain or add oil until it reaches the full level…never lower nor higher.

You have a valve train problem with your riding lawnmower

The valve train in your riding mower can smoke due to a burnt valve. In the case of a burnt valve, it is a valve that has been overheated. Extremely hot mufflers can indicate a faulty valve or timing issue.

A leak-down test can only reveal valve problems once the cylinder head has been removed. Repair and testing of this engine should be done by a small engine mechanic.

When the valve is burned, the seat and the valve must be cut at specific angles. This will ensure that the repair is done correctly and the combustion chamber is completed.

White or blue smoke from my lawn mower is dangerous?

The short answer is yes. You and your lawnmower are at risk of white/blue smoke from lawnmowers. A doctor doesn’t need to tell you not to breathe in smoke resulting from burning oil. If oil is burning on the lawn mower, it needs to be inspected. This is the first sign of a larger problem. Other parts of your mower, such as the air filter and spark plugs, can be damaged by oil. However, oil can also damage engine parts that shouldn’t come into contact with it. Even if you notice your lawn mower is smoking, make sure you take the time to investigate the problem. If your lawn mower produces black smoke, you may face a different set of problems.

It may be that black smoke indicates that the mower is burning too much gasoline, or running rich.

The ratio of gasoline to air in your lawn mower’s carburetor is controlled by its carburetor. When the carburetor doesn’t get enough air, gasoline gets more blended into the mixture, creating black exhaust smoke. A dirty or clogged air filter might be preventing adequate airflow into the carburetor. It may be necessary to replace the air filter. (Air filters vary depending on mower model; view an example air filter on Amazon.) Next, run your lawn mower. Increasing airflow may be needed to resolve the black smoke if the carburetor needs adjustment. The carburetor of your mower should be adjusted either by a professional or by the user according to the instructions in your owner’s manual.
