The lawn mower is an essential tool for maintaining a well-manicured lawn. With regular use, it’s inevitable that the spark plugs will need to be replaced. But before you can replace them, you need to know how to take them out. In this article, we will guide you through the process of removing spark plugs from your lawn mower. We will cover the necessary steps, precautions, and tools required to ensure a successful and safe removal process.
Why Spark Plug Replacement is Important
Spark plugs play a crucial role in the functioning of your lawn mower. They generate the spark that ignites the fuel-air mixture in the engine, allowing it to run efficiently. Over time, spark plugs can wear out, leading to decreased engine performance, misfires, and even engine damage. Regular replacement of spark plugs is essential to maintain your lawn mower’s performance and extend its lifespan.
Preparation and Safety Precautions
Before starting the process, make sure you have the following:
- A spark plug socket or wrench
- A spark plug gap gauge
- A clean and well-lit workspace
- A pair of gloves and safety glasses
It’s also essential to disconnect the spark plug wire from the spark plug to prevent any accidental starts or electrical shocks. To do this, locate the spark plug wire and gently pull it off the spark plug. You may need to use a spark plug wire puller to remove it.
Removing the Spark Plug
The process of removing the spark plug varies depending on the type of spark plug and lawn mower you have. Here’s a general guide:
Step 1: Locate the Spark Plug
Identify the spark plug location on your lawn mower. It’s usually located on the side of the engine or on top of the cylinder head. Consult your lawn mower’s manual if you’re unsure.
Step 2: Remove the Spark Plug Wire

Step 3: Use a Spark Plug Socket or Wrench
Insert the spark plug socket or wrench into the spark plug and turn it counterclockwise until it’s loose. For spark plugs with a rubber grommet, you may need to use a spark plug socket with a built-in rubber grommet.
Step 4: Remove the Spark Plug
Once the spark plug is loose, remove it from the engine by pulling it straight out. Be careful not to touch any of the engine components with your bare hands, as they can be hot.
