Maintaining your lawn mower is essential to ensure it runs smoothly and efficiently. One crucial part of this maintenance is replacing the spark plug, which can be a daunting task if you don’t have the right tools. Toro, a well-known brand in the lawn care industry, manufactures a variety of lawn mowers that require different spark plug sizes. In this article, we will explore the different types of spark plugs used in Toro lawn mowers, the socket sizes required to remove them, and provide a step-by-step guide on how to replace a spark plug.
Understanding Spark Plugs and Their Importance
Spark plugs play a critical role in the functioning of your lawn mower’s engine. They are responsible for igniting the fuel-air mixture inside the engine’s cylinders, which powers the mower. A worn-out or faulty spark plug can lead to poor engine performance, reduced fuel efficiency, and increased emissions. It is essential to replace the spark plug regularly to ensure your lawn mower runs smoothly and efficiently.
Types of Spark Plugs Used in Toro Lawn Mowers
Toro lawn mowers use different types of spark plugs, depending on the model and engine type. The most common types of spark plugs used in Toro lawn mowers are:
Spark plugs with a 13/16″ or 5/8″ hex size are commonly used in Toro lawn mowers with small engines. These spark plugs are usually found in walk-behind mowers and small ride-on mowers.
Spark plugs with a 3/4″ or 14mm hex size are used in larger Toro lawn mowers with more powerful engines. These spark plugs are usually found in large ride-on mowers and zero-turn mowers.
Determining the Correct Socket Size
To determine the correct socket size for your Toro spark plug, you need to check your lawn mower’s manual or consult with a professional. The manual should provide information on the type of spark plug used and the recommended socket size. If you cannot find the information in the manual, you can also check the spark plug itself for any markings or labels that indicate the hex size.

What is the standard socket size for a Toro spark plug?
The standard socket size for a Toro spark plug is typically 13/16 inches or 0.8125 inches (20.64 mm). However, it’s essential to note that spark plug socket sizes can vary depending on the specific Toro model and engine type. It’s crucial to consult the owner’s manual or manufacturer’s website to determine the correct socket size for your particular Toro spark plug.
Using the correct socket size is vital to avoid damaging the spark plug or the engine. A socket that’s too small may not provide a secure fit, while a socket that’s too large can round the spark plug’s edges or damage the spark plug well. To ensure a proper fit, it’s recommended to use a socket that’s specifically designed for spark plugs, as these sockets typically have a rubber or foam insert that helps to grip the spark plug and prevent it from becoming damaged during removal.
How do I determine the correct socket size for my Toro spark plug?
To determine the correct socket size for your Toro spark plug, you can start by consulting the owner’s manual or manufacturer’s website for specifications. You can also inspect the spark plug itself, as the socket size is often listed on the spark plug’s packaging or on the spark plug’s base. Additionally, you can measure the spark plug’s diameter using a caliper or ruler to determine the correct socket size. It’s essential to use a socket that matches the spark plug’s diameter to ensure a secure fit and avoid damaging the spark plug or engine.
If you’re still unsure about the correct socket size, you can visit a local hardware store or home improvement center and ask for assistance. Many stores carry a variety of spark plug sockets, and the staff may be able to help you determine the correct size for your Toro spark plug. Alternatively, you can purchase a spark plug socket set, which typically includes multiple sockets in different sizes, to ensure you have the correct size for your Toro spark plug.
Can I use a universal spark plug socket on my Toro spark plug?
A universal spark plug socket can be used on a Toro spark plug, but it’s not always the best option. Universal spark plug sockets are designed to fit a range of spark plug sizes, but they may not provide a secure fit on every spark plug. If the universal socket is too loose or too tight, it can damage the spark plug or the engine. However, if you have a universal spark plug socket that matches the correct size for your Toro spark plug, it can be a convenient and cost-effective option.
Before using a universal spark plug socket on your Toro spark plug, make sure to check the socket’s size range and ensure it matches the specifications for your spark plug. It’s also essential to inspect the socket for any signs of wear or damage, as a damaged socket can compromise the fit and potentially damage the spark plug or engine. If you’re unsure about the correct size or the condition of the universal socket, it’s recommended to consult the owner’s manual or manufacturer’s website for guidance or to purchase a socket specifically designed for your Toro spark plug.
What are the consequences of using the wrong socket size on my Toro spark plug?
Using the wrong socket size on your Toro spark plug can have serious consequences, including damaging the spark plug, the spark plug well, or the engine. A socket that’s too small may not provide a secure fit, which can cause the spark plug to become rounded or damaged during removal. On the other hand, a socket that’s too large can damage the spark plug’s threads or the spark plug well, which can lead to costly repairs.
In addition to damaging the spark plug or engine, using the wrong socket size can also compromise the performance and safety of your Toro equipment. A damaged spark plug can lead to poor engine performance, decreased power, and increased emissions. In extreme cases, a damaged spark plug can cause the engine to misfire or fail, which can lead to accidents or injuries. To avoid these consequences, it’s essential to use the correct socket size for your Toro spark plug and to follow proper removal and installation procedures.
How do I properly remove a Toro spark plug using a socket?
To properly remove a Toro spark plug using a socket, start by locating the spark plug and ensuring the engine is cool. Next, insert the socket into the spark plug well and turn it clockwise to secure it in place. Then, use a ratchet or wrench to turn the socket counterclockwise and loosen the spark plug. Once the spark plug is loose, you can remove it from the well and replace it with a new one.
When removing the spark plug, be careful not to touch the spark plug’s electrodes or the spark plug well, as the oils from your skin can compromise the spark plug’s performance. Additionally, make sure to use a socket that’s specifically designed for spark plugs, as these sockets typically have a rubber or foam insert that helps to grip the spark plug and prevent it from becoming damaged during removal. After removing the spark plug, inspect the spark plug well for any debris or damage and clean it out if necessary before installing a new spark plug.
Can I use a spark plug socket with a rubber insert on my Toro spark plug?
Yes, you can use a spark plug socket with a rubber insert on your Toro spark plug. In fact, spark plug sockets with rubber inserts are recommended for removing spark plugs, as they help to grip the spark plug and prevent it from becoming damaged during removal. The rubber insert also helps to protect the spark plug’s electrodes and prevent them from becoming damaged or compromised.
When using a spark plug socket with a rubber insert, make sure to inspect the insert for any signs of wear or damage before use. A damaged or worn-out rubber insert can compromise the fit and potentially damage the spark plug or engine. Additionally, make sure to clean the spark plug well and the spark plug socket before use to ensure a secure fit and prevent any debris from compromising the spark plug’s performance. By using a spark plug socket with a rubber insert, you can help to ensure a safe and successful spark plug removal and installation.
