How to Fix a Lawn Mower

By January 11, 2017 No Comments

Your lawn mower is one of the most important pieces of equipment you have. That becomes even more apparent when it stops working. The problem when that happens is you may not always have time to take it to a repair shop, or worse what if it breaks down in the middle of cutting your yard? It can be very helpful to have some basic knowledge about fixing your lawn mower. Here are a few steps you can take to fix your lawn mower if it breaks down.

  1. Disconnect and examine the spark plug

This action also acts as a safety measure since as there is no way the mower can accidentally start if the spark plug is disconnected. Just like when you mow you’ll want to wear eye protection and gloves. Once you have the spark plug disconnected, check it for damage. It may show signs of worn metal, which is a result of not having clean oil. If this is the case, then it’s time to change your oil.

  1. Checking the Ignition System

In this step, you’ll want to check to make sure there is a small gap between the magnets in the flywheel and the magneto. You’re making sure there are no mix-ups in this area. Be careful not to touch anything with metal, so you avoid electrical shocks. Also, now is a good time to inspect your battery to see that it is well charged.

  1. Cleaning the carburetor

Now it’s time to clean your carburetor. Your lawn mower will run much smoother when the carburetor is in good clean working condition. Upon inspection, if you find that it is dusty or dirty you can clean it by soaking the metal parts in gasoline. The plastic parts can be cleaned the same way however please be sure not to leave them soaking as long. Another point to make on the carburetor is to clean the jet, ensuring there are no clogs in any of the tubings.

  1. The Fuel Tank

There have been some cases where lawn mowers don’t work simply because the hole in the gas cap is clogged up. Of course, if you don’t have the type of lawn mower that has this kind of gas cap it’s not something you need to be concerned about. However, if your model is one that has a hole in the gas cap make sure it remains unclogged so your lawn mower works properly.

  1. Checking the spark arrestor

The spark arrestor is designed to prevent your lawn mower from catching fire. To clean it you’ll just need to brush it with a wire brush to remove any gunk. Note that some lawn mowers come with detachable spark arrestors while others do not. Either way, the cleaning process is the same.

These are some of the basic things you can look into if your lawn mower isn’t working properly. Most of the other parts are more delicate and disassembling and reassembling them probably requires a level of expertise that most users don’t have. You should consult a professional repairman if you’re not able to resolve any issues using the information above. You should keep a good maintenance schedule for your lawn mower because in the long run doing so will keep your repair costs down and your machine will last longer.
