Lawnmower

You’re out in your lawn, ready to finish that lawn-mowing job you started a few hours ago. You go to start the lawn mower use and nothing happens. The lawnmower won’t start! What do you do now? Don’t worry; this is a common problem with lawn mowers, and there are steps you can take to fix it before heading inside for the day. In this blog post, we’ll show you how to identify your lawn mowing issue, troubleshoot it, and get back on track quickly!

Check for clogged fuel line

A clogged fuel line is a very common reason for lawn mowers not starting. To check your lawn mower’s fuel line, tip it on its side and look at the narrow tube that runs from the gas tank to the engine (this will also be where you add new gasoline). This small hose carries gas from the lawn mower’s gas tank to its engine. If you spot anything blocking this hose, like a small piece of debris or grass clippings, remove it and try starting your lawnmower again.

Clean out the carburetor and air filter

Another common lawn mower issue that can prevent it from starting is a dirty carburetor or clogged air filter. If your lawnmower’s engine will turn over but won’t start, remove the lawn mowing deck and check the inside of the lawn mower for dirt and grass clipping buildup around its carburetor (located behind the lawn mower’s air filter). If you find any, remove the debris and try starting your lawnmower again.

If grass clippings are blocking airflow in the lawn mower’s carburetor or if dirt buildup is preventing it from properly mixing fuel with air to facilitate combustion (which makes gas go boom), this can cause problems for lawnmowers just like it can for cars. Cleaning out the lawn mower’s air filter and carburetor will help your lawnmower start up again, which you can do easily by following Steps One through Three in our blog post on How to Change a Lawn Mower Air Filter.

Make sure you have gas in the tank

Don’t forget that lawnmowers need gas to run! Make sure your lawnmower’s tank is full before you try starting it up again. If there isn’t enough gas in the lawnmower, this can cause problems for lawn mowing equipment just like it does for cars and trucks. To avoid damage or engine failure due to lawn mowing equipment running out of gas, fill lawn care equipment’s tanks up before you use them.

If none of these work, it might be time to buy a new lawnmower!
