Imagine you are about to start your work, and out of the blue, you figure out that your lawn mower not turning over.

Sometimes, people only think of bigger issues and overlook the simple minor faults that can lead us to experience such troubles.
But if minor fixes can save your time and money, why would you want to invest in professional servicing for minor fixings.
That’s why I have decided to present a quick, easy, and cost-effective DIY method of troubleshooting a lawn mower that does not turn over.
Things required to troubleshoot the lawn mower not turning over:
Have a proper glance at the checklist of the required tools and materials:
| Tools | Materials |
| Standard Mechanical toolkit | Spark plug cleaner |
| Socket | New Spark plug & lead (if needed) |
| Spark plug tester | New Battery (if required) |
| Wire brush | New Starter kit (if necessary) |
| Safety Gloves | Solenoid replacement kit (if needed) |
Step 1- Check the Spark plugs & Spark plug lead:
As soon as you encounter such troubles, you should make sure that the spark plugs and the plug lead are in good working condition.
First, you should check whether the spark plugs are operating properly or defected because the mower won’t turn over with a defective spark plug on it.
To inspect, disconnect the lead and clean the surrounding area. Then, use a socket to remove the plug.
Next, if the plug looks dirty, clean it with a wire brush and a spark plug cleaner. Then reinsert it again and ensure it fits into the position securely.
If the spark plug looks damaged, cracked, or broken, you should replace it.
After that, you should inspect the spark plug lead with a spark plug tester or multimeter.
Connect one tester prong to the spark plug lead and the other end to the spark plug. Then, try to start the engine and verify the result with your mower’s user manual. If required, replace the spark plug lead.
Step 2- Check the Battery, Solenoid & Starter:
While checking the spark plugs and plug lead’s state, do not forget to inspect the condition of the battery and solenoid.
