- Clean Rag or Paper Towel: Having a clean rag or paper towel handy will allow you to wipe away any debris or dirt that may have accumulated around the spark plug area, ensuring a clean work environment.
- New Spark Plug: It is essential to have a new spark plug on hand for replacement. Make sure to choose the correct spark plug for your specific lawn mower model.
- Insulated Pliers: Insulated pliers will come in handy when disconnecting and reconnecting the ignition cable, ensuring your safety throughout the process.
Having these tools readily available will enable you to change the spark plug efficiently and effectively, ensuring the optimal performance of your lawn mower.
With the necessary tools at your disposal, you’ll be well-equipped to tackle the task of changing your lawn mower’s spark plug. Remember to always refer to your owner’s manual for specific instructions and safety precautions before attempting any maintenance or repair on your lawn mower.
Steps to Remove and Replace the Spark Plug
When it comes time to change your lawn mower’s spark plug, following the proper steps is essential. By following these instructions, you can ensure a smooth and successful spark plug replacement process.
Step 1: Stage the Lawn Mower
Begin by staging your lawn mower on a flat surface. Turn off the engine and remove the ignition key to prevent accidental starting. This will provide a safe and stable workspace for the spark plug removal and replacement.
Step 2: Disconnect the Ignition Cable
Locate the ignition cable connected to the spark plug. Gently grasp the plug wire boot, the rubber covering at the end of the cable, and carefully twist and pull it away from the spark plug. This will disconnect the ignition cable from the plug.
Step 3: Remove the Old Spark Plug
Using a spark plug socket and socket wrench, fit the socket over the spark plug and turn counterclockwise. Apply steady pressure until the plug begins to loosen. Continue turning until the plug is completely removed from the engine.
Step 4: Inspect the Old Spark Plug
Take a close look at the removed spark plug to inspect its condition. Look for signs of wear, such as erosion, carbon buildup, or oil deposits. These issues can indicate problems with your mower’s engine and may require further inspection or maintenance.
Step 5: Clean and Install the New Spark Plug
Before installing the new spark plug, use a clean rag or paper towel to clean any debris or dirt from the spark plug socket in the engine. Then, carefully thread the new spark plug into the socket by hand. Once hand-tightened, use the spark plug socket and wrench to give it a final snug turn.
Step 6: Reconnect the Ignition Cable
With the new spark plug securely in place, it’s time to reconnect the ignition cable. Simply align the plug wire boot with the spark plug and push it on firmly until it clicks into place. This will ensure a proper connection and secure fit.
Following these steps will allow you to successfully remove and replace the spark plug in your lawn mower, helping to maintain its performance and efficiency.

Alternative Methods for Spark Plug Removal Without a Socket
If you don’t have a spark plug socket on hand, don’t worry. There are alternative methods you can try to remove the spark plug from your lawn mower. Here are a few techniques that can help:
1. Removing spark plug by hand
If the spark plug is not installed tightly, you can try removing it by hand. Make sure the engine is cool, then simply grip the spark plug firmly and turn it counterclockwise to loosen and remove it.
2. Using lubricants
If the spark plug is stuck, using a lubricant like WD-40 can help loosen it. Spray the lubricant around the base of the spark plug and let it sit for a few minutes. This can help break down any debris or rust that might be causing the plug to stick. Use a wrench or pliers to carefully turn the plug counterclockwise and remove it.
3. Rubber hose method
Another method involves using a rubber hose for grip and leverage. Slide a piece of rubber hose over the spark plug, ensuring a tight fit. Then, firmly grasp the hose and rotate it counterclockwise to loosen the plug. This technique can provide you with better grip and leverage to remove the spark plug without a socket.
4. Aluminum foil method
The aluminum foil method is where you use a wider deep socket and aluminum foil to remove the spark plug. Fold a small piece of aluminum foil and wrap it around the plug’s ceramic insulator, creating a snug fit. Then, place the deep socket over the foil-wrapped spark plug and use a wrench to turn it counterclockwise to remove the plug.
5. Other wrench or pliers method
If none of the above methods work, you can try using other wrench or pliers to grip the spark plug’s base and turn it counterclockwise to remove it. However, be cautious and ensure that the wrench or pliers fit securely on the spark plug to avoid damaging the plug or the engine.
Remember, always exercise caution when working with spark plugs. If you’re unsure or uncomfortable with removing the spark plug without a socket, it’s best to consult a professional or refer to your owner’s manual for guidance.
Proper maintenance of your lawn mower’s spark plug is essential for ensuring optimal performance and longevity. By regularly inspecting, cleaning, and replacing spark plugs, you can enhance fuel efficiency, boost engine power, and prevent potential damage.
Regular spark plug maintenance is key to maintaining lawn mower performance. Inspecting the spark plug for signs of wear or damage, such as oil or carbon buildup, can help you identify when it’s time for a replacement. Replacing spark plugs annually or after 30 engine hours is recommended to ensure reliable ignition and smooth operation.
Remember, safety should always be a priority when working with spark plugs. Consult your owner’s manual or seek guidance from a certified technician if you have any questions or concerns. With proper spark plug maintenance, you can keep your lawn mower running smoothly and efficiently, and enjoy a well-maintained and beautiful yard.
