Taking out a spark plug from a lawn mower might seem like a daunting task for some, but with the right knowledge and tools, it can be a straightforward process. This article will guide you through the steps involved in removing a spark plug from a lawn mower, ensuring that you can perform this task with ease and confidence.

Tools and Materials

Before diving into the process, it’s essential to gather the necessary tools and materials. Here’s what you’ll need:

1. Socket Wrench: A socket wrench with a spark plug socket attachment is required to loosen and remove the spark plug.

2. Spark Plug Socket: This specialized socket is designed to fit snugly around the spark plug, ensuring a secure grip during removal.

3. Ratchet Handle: A ratchet handle is used in conjunction with the socket wrench to provide leverage and make the removal process easier.

4. Gloves: Wearing gloves will protect your hands from any potential injuries and provide a better grip on the tools.

Step-by-Step Guide

Now that you have the necessary tools, let’s dive into the step-by-step process of removing a spark plug from a lawn mower:

Step 1: Ensure Safety Precautions: Before starting any work on the lawn mower, make sure it is turned off and the spark plug wire is disconnected. This will prevent accidental starting of the engine and reduce the risk of electric shock.

Step 2: Locate the Spark Plug: The spark plug is typically located on the side or top of the engine cylinder. It is connected to a thick wire, known as the spark plug wire.

Step 3: Remove the Spark Plug Wire: Gently pull the spark plug wire off the spark plug. It may require a slight twisting motion to release it. Set the wire aside in a safe place, away from the spark plug hole.

Step 4: Loosen the Spark Plug: Attach the spark plug socket to the socket wrench and place it over the spark plug. Turn the wrench counterclockwise to loosen the spark plug. Initially, it may require some force to break the initial resistance.

Step 5: Remove the Spark Plug: Once the spark plug is loosened, continue turning the socket wrench counterclockwise until you can remove the spark plug by hand. Be careful not to drop the spark plug into the engine compartment.


Removing a spark plug from a lawn mower is a relatively simple process that requires the right tools and a few easy steps. By following the steps outlined in this article, you can safely and effectively remove the spark plug from your lawn mower, allowing for maintenance or replacement as needed.
