There are actually a number of reasons why this may happen. Here are a couple of things that you can check:

Moisture – More often than not, the cause of the mower dying after a few minutes is moisture in the petrol tank.This can happen for a number of reasons from cutting wet grass to condensation. If this is the case, then the best thing to do is completely empty your fuel tank and then refill it and try again.

Clogged Air Filter – Another common cause of a lawn mower starting and then dying after a few minutes is a clogged air filter. This can happen because of debris from mowing the lawn getting clumped together. To avoid this from happening it is important to regularly clean your mower after use. If you already have a clogged filter then it is a simple process to remove and clean it.

Wrong Cutting Height – This is less common, but it does happen. If you are trying to cut particularly tall grass, then you do need to make sure that you have the cutting height on your mower set correctly. Most mowers will allow you to raise and lower the height. If you have it set too low then it will cause the mower to cut out during use.

Dirty Spark Plug – Again, this is a less common occurrence, but it is definitely something that is worth checking if you are struggling to keep your lawn mower going. It is actually really easy to get too much dirt and debris around the spark plug and when this happens it can cause the mower to cut out. A simple search online will show you how to remove the spark plug to clean it so that you can see if this is the problem.

Mower Won’t Start After Winter

This is actually a very common problem that is reported by people who have stored their petrol lawn mower during the winter months and tried to use it once the weather is warmer, only to discover that it no longer works. Sometimes it is simply the case that the lawn mower has stopped working completely. However, there are instances in which there is actually a simple fix. Here are a couple of things that you can check if your mower won’t start after winter.

If you left petrol in the tank over the winter months whilst your petrol mower was in storage, then the chances are that this is what is causing it to no longer start. Start by emptying the petrol that has been left in the tank and then refilling it with fresh fuel. It is very likely that this will fix the problem and you will be able to use your mower again.

Clogged Carburetor – One of the things that happens when you leave petrol in the tank for a long period of time is that it can change consistency and become gummy. This can lead to the carburetor becoming clogged. This will cause the mower to stop working completely. If you feel confident enough then you can remove the carburetor yourself to clean it. Alternatively, there are products that you can buy which will unclog it without the need for taking things apart.

The Oil – This may sound fairly obvious, but a lot of the time the cause of a petrol mower not starting is simply that the oil level is too low. Fortunately, this is very easy to check and very easy to fix. If you have checked and noticed that the oil level is too low then simply top it up. However, if it has been sitting over winter then it is a good idea to empty the oil and put some fresh in as this is more likely to fix the problem long term.

As you can see, there are so many reasons that could be behind your lawn mower not starting and a lot of these reasons are actually very easy to fix. If your petrol mower isn’t starting then try going through each of the points mentioned above to see if there is a simple cause and a simple fix.
