How to start a lawn mower with a bad starter

Starting your riding mower is the first step in any lawn mowing job. So what do you do if your mower doesn’t start? It could be the lawn mower starter or the battery. When your mower won’t start, and you need to get the job done, it is time to troubleshoot and find an alternative method to get that machine running. 

Importance of troubleshooting and alternative methods

In this short guide, we will look at the components of the starter system. We will then look at how to diagnose the issue. Repair or replace the offending part and get back on the lawn again. 

Understanding the Starter System

Definition and function of a starter in a lawn mower

The whole point of an engine starter is to initiate the combustion process by turning the engine. This could be a pull-start rope, but with larger machines, it’s a little more complicated than that. The key components are a solenoid, the starter motor, ignition switch and of corse a spark plug.

The solenoid relay switch receives an electrical signal when turning the ignition key. Once this is activated, a current flows from the battery to the starter motor, which cranks the engine and starts the machine. 

Common symptoms of a bad starter

The most common symptom is the dead click you hear when you turn the key to start the engine. The first thing to check is the battery. Once you have ruled out a flat or faulty battery, You need to replace the spark plug. If that does not work, it is the connections, ignition swatch, or the starter solenoid. 

Now, let’s identify where the issue lies and fix it.

Troubleshooting a Bad Starter

If you suspect that you have a faulty starter motor, the first step is to confirm that this is indeed the issue. Start by replacing the spark plug or pulling off the existing plug and checking for a spark. If this is fine, move on to the battery and confirm it has enough charge. Check the connections; if you have a rat tail file, you could try filling the inside of the battery terminal connectors and replacing them. I have had this fix the issue before. 

Failing that, check the condition of the connection cable. If that looks fine, it is either the starter motor or the solenoid. It’s had to explain how to do that in writing, so this video walks you through that process.
