15 Lawn Mower Problems You Can Fix Yourself

Your lawnmower is not working, so now the most common thing you see first is the fuel system. Before you take any step, you are required to check the fuel level and quality. If the tank is low, refill it. But if the fuel is sitting for more than 30 days, then it has become stale and causes problems. 

In such a case, you drain the old fuel by siphoning it. As you drain the fuel, replace it with fresh gasoline. Besides, if you want to store the fuel for an extended period, then use a fuel stabilize. 

Yet another common culprit for the lawn mower problem is those dirty spark plugs. You locate the spark plug and remove it. Furthermore, use a socket wrench and inspect it for any signs of dirt or damage. 

If you notice a layer of deposits, you can clean it with a wire brush and remove the buildup. Although, if the spark plug is cracked or severely corroded, it’s best to replace it with a new one. As a damaged spark plug can hinder the ignition process and lead to poor engine performance. 

One of the simple maintenance ways to deal with lawn mower problems is a stuck starter rope. It happens because the flywheel brake's element is engaged. The flywheel is a safety feature designed to prevent the mower from starting when the blades are not in a safe position. 

Check the flywheel brake level to ensure it is fully disengaged. The next step is to inspect the mower blades for obstructions. Grass clippings and other debris can lodge around the blades. Tilt the mower on its side and visually inspect the blades for any blockages. 

If the lawnmower's blade is dull, it can affect its cutting performance. Look for signs of wear or tear. If they are just simply dull, sharpen them using the blade sharpener. 

Safely remove the mower blades as you lose the bolts that hold them in place. Secure the blade and carefully sharpen the cutting edge. If they are excessively worn, it’s best to replace them entirely. 

Sometimes, smoke from your lawn mower may occur. This is the classic sign of an oil issue. The smoke occurs when the oil level is too high, causing excess oil to burn off and produce smoke.

In certain cases, smoke also shows serious problems, such as worn piston rings that allow it to enter the combustion chamber. To deal with this, you check the oil level and drain the unwanted oil to the required level.

But if the smoke persists, then look around for the leak and check the piston rings for damage. 

Everything looks good when you use a lawnmower, but then it becomes slow. This happens due to the buildup of grass debris under the mower deck, which can hinder the blades' movement and decrease performance.

You should clean the underside of the mower deck and remove the debris that obstructs the blade. Then, check the air filter and clean it. In a severe situation, the better choice is to replace it. 

Excessive vibration can be a surprising lawn mower problem. It is likely due to the blades. Inspect the mower blades for signs of wear and tear. Loose blades can also significantly increase vibration.

You can fix them by tightening them securely using the appropriate tool. Despite all these, if you notice any damage, replace the blades immediately to prevent further issues. 

Sometimes, the lawn mower loses power while you mow. It is one of the biggest lawn mower problems. The solution to this problem is straightforward. It happens due to a dirty air filter. 

Check the air filter and clean or replace it as needed. In addition, clear any debris from the deck to allow for proper airflow and optimal cutting power. 

Apart from that, your lawn mower can encounter a clog in the mower deck or an engaged engine brake. Inspect the engine brake to ensure it is fully disengaged; sometimes, it can accidentally remain on.

If the brake is fine, inspect the underside of the mower for any grass debris that may have built up. Then, clean the mower deck to reduce resistance and make it easier to pull the starter cord.

If the power mower experiences a battery issue, then it's time to work with the battery checking. First, check if the batter is fully charged since the low amount can hamper the power mower's performance. 

Aside from that, look for the connections between the battery and the mower to ensure they are secure and tight. Inspect the battery terminals for any signs of corrosion, like white or green buildup.

Clean the terminals carefully using a battery terminal cleaner and then provide a thorough drying. If the battery continues to underperform, then it is time to change it. 

While regular oil changes are needed, there may be times when the engine oil breaks down and becomes contaminated with dirt and combustion byproducts. This can reduce the effectiveness of the lubricant and protect the engine component. 

You can address the issue by changing the oil, as mentioned in the mower's manual. This means changing the pillar every 25-50 hours of use. The fresh oil helps to keep the engine running smoothly and extend the life of your mower. 

When the fuel filter is obstructed, it is a severe lawnmower problem that requires your attention and specific actions. Locate the fuel filter and inspect it for any signs of blockage or buildup. If you notice that the filter is dirty, it likely needs to be replaced.

Turn off the fuel supply and relieve any pressure in the fuel line. Then, disconnect the fuel lines from the filter and take care to catch any spilt fuel in a container. Replace the old filter with a new one. After replacing the clogged fuel filter, try starting your mower again.

Aside from other problems, the pull cord is a common lawn mower problem. If it gets stuck or is difficult to pull, it is caused by an obstruction under the mower.

As usual, you start with a regular check under the mower to see if there is any blockage. If the cord appears worn, then it should be replaced to restore smooth operation. 

Sometimes, the lawn mower can backfire. It is the classic sign of startling and unsee engine issues. To resolve this, you should rain the old fuel and replace it with fresh oil.

Then, clean the carburettor to remove any debris that may be causing the improper fuel flow. Furthermore, the best way to prevent these lawnmower problems is to do regular maintenance. 

While you are aware of the lawn mower problem, what causes it? Knowing these can help you prevent this kind of situation. 

A lawn mower that keeps cutting off can be frustrating, and several common issues may be causing this problem. 

Overworking the Mower

The basic cause of lawn mower problems is overworking, especially if the grass is too tall or dense. When the mower struggles to cut through thick grass, it is a classic sign of exhaustion.

Further, this can lead to stalling. To reduce this, consider raising the mower deck height or mowing in smaller sections.

Old Fuel

If the fuel in your tank is too old, then it can not ignite properly. At the same time, it can cause the engine to sputter and die. You should drain the old fuel and replace it with fresh gasoline.

Obstructed Carburetor

An obstructed carburettor can prevent the proper air-fuel mixture from reaching the engine and becoming an obstruction. Cleaning the carburettor can help restore proper function.

Clogged Air Filter

If the air filter is dirty, it can restrict airflow to the engine. Further, it makes it difficult for the mower to run smoothly. Inspect and replace a clogged air filter to improve performance.

Faulty Spark Plug

A dirty spark plug can affect ignition. It causes the mower to start and then die. Cleaning or replacing the spark plug is a straightforward fix for that lawn mower problem.

Blocked Fuel Cap

If the fuel cap is clogged, a vacuum can be created in the fuel tank. These have prevented the fuel from flowing to the engine.

Electrical Issues

For electric mowers, problems with the power cable can cause intermittent cutting out. Inspect the cable for damage and ensure the motor is functioning properly. 

The best way to prevent lawn mower problems is to find a way to use it properly. Let's find out what they are

• The first thing is to understand the basics of the mower's manual, including safety instructions, maintenance tips, and specific operating guidelines.
• Check for damage or loose parts and ensure the blades are sharp. Confirm that there is enough oil and fuel before starting.
• Remove rocks, sticks, and other debris from the lawn to prevent damage to the mower.
• To avoid scalping the lawn set the mower’s deck to the appropriate height for your grass type and season.
• For gas mowers, prime the engine if needed, then pull the cord or use the electric starter according to the instructions.
• Overlap slightly with each pass to avoid missed patches, and change directions each time you mow to prevent rutting.
• Mow when the grass is dry to prevent wet clippings from clogging the mower deck.
• Mow at a consistent speed that’s comfortable for you and the mower. Avoid the rush to ensure a clean, even cut.
• When finished, turn off the mower and wait for the blades to stop completely before inspecting it.
• Clear the underside of the deck of grass clippings and debris, and store the mower in a dry place.

Now, you might wonder what the lawn mower can do for you. Apart from mowing the grass, it has other beneficial uses that make it a beneficial part of our tool collection.

Maintain Lawn Health

Regular mowing helps keep the grass at an optimal height. At the same time, it promotes healthy growth and prevents weeds from taking over. The consistent cutting allows the more vital grass shoots to thrive.

Besides, it keeps the weaker ones trimmed away and makes way for a healthier lawn overall.

Nutrient Recycling

When you mow, the clippings can be left on the lawn to decompose. These can return the valuable nutrients to the soil. The natural process enhances soil fertility and supports further grass growth.

Weed Control

We might not say that mowing regularly can cause lawn mower problems, but it can effectively cut down weeds and give the grass a competitive edge.

Since grass tends to recover faster than weeds, regular mowing helps keep the weed population in check without the need for chemical herbicides.
