Common Lawn Mower Issues & How to Fix Them

Lawn mowers are an essential tool for maintaining a healthy and well-manicured lawn. However, like all machines, they can break down and need repair. In this post, we will go over some common issues that can arise with lawn mowers and how to fix them.

  1. Blade Repair

One of the most common issues with lawn mowers is a dull or damaged blade. This can cause uneven cuts and can even be dangerous if the blade becomes too damaged. To fix this issue, you will need to remove the blade from the lawn mower. This can usually be done by removing the nut or bolt that holds it in place and then lifting the blade off.

Once the blade is removed, you can either sharpen it or replace it if it is too damaged. To sharpen the blade, you can use a file or a bench grinder. Be sure to follow the manufacturer's recommendations for the angle and number of passes you should make. If the blade is beyond repair, you can purchase a new one from a hardware store or online.

  1. Spark Plug Issues

Another common problem with lawn mowers is a faulty spark plug. This can cause the lawn mower to not start or to run poorly. To fix this issue, you will need to locate the spark plug, which is usually located near the top of the engine.

To remove the spark plug, you will need a spark plug wrench. Once the spark plug is removed, you can check it for damage. If it is dirty or damaged, you can clean it with a wire brush or replace it with a new one.

  1. Clogged Fuel System

If your lawn mower is not starting or is running poorly, it could be due to a clogged fuel system. This is typically caused by old gasoline that has become contaminated with water or debris. To fix this issue, you will need to drain the fuel tank and refill it with fresh gasoline. You should also check the fuel filter for any blockages and replace it if necessary.

  1. Stalling Engine

If your lawn mower's engine is stalling, it could be due to a number of issues. One common cause is a dirty air filter, which can restrict the flow of air to the engine. To fix this issue, you will need to locate the air filter and clean it or replace it with a new one.

Another common cause of stalling is a faulty ignition system. This can be caused by a faulty spark plug, ignition coil, or other component. If you suspect this is the issue, you may need to take your lawn mower to a professional for repair.

  1. Leaking Oil

If you notice oil leaking from your lawn mower, it is important to address this issue as soon as possible. Oil leaks can be caused by a variety of issues, such as a faulty gasket or a cracked oil pan. To fix this issue, you will need to locate the source of the leak and either repair or replace the damaged component.


By following these steps, you should be able to fix common issues with your lawn mower and get it running smoothly again. If you are unsure about how to proceed or if the problem is more complex, it is always a good idea to consult a professional or refer to the manufacturer's instructions. With proper maintenance and repair, your lawn mower should provide reliable service for many seasons to come.
