The whirring of a lawn mower engine is a familiar soundtrack of summer. But what happens when that engine sputters and dies, leaving your grass a tangled mess? Oftentimes, the culprit is a faulty spark plug. Replacing it can be a simple fix, but only if you have the right tools – specifically, a spark plug socket. This article will guide you through understanding the common spark plug socket sizes for Toro lawn mowers, helping you make the right choice for your model.
Quick Answer: The most common spark plug socket size for Toro lawn mowers is 5/8 inch (16mm) with a 3/8-inch drive. However, there are exceptions, and checking your owner’s manual or verifying the spark plug itself is crucial.
Determining Your Spark Plug Socket Size
The journey to finding the right spark plug socket begins with knowing what type of spark plug your Toro lawn mower uses. This information is readily available in your owner’s manual, and you can also decipher it from the spark plug itself.
1. Checking Your Owner’s Manual:
- Consult the manual: Your owner’s manual will provide detailed specifications for your Toro lawn mower, including the recommended spark plug type and the corresponding socket size.
- Locate the section on maintenance: The spark plug replacement instructions are typically found in the maintenance section of the manual.
2. Inspecting the Spark Plug:
- Locate the spark plug: The spark plug is usually found on top of the engine, often near the air filter.
- Look for markings: The spark plug itself often has markings indicating its size, such as “5/8” or “16mm.” This will correspond to the socket size you need.
3. Understanding the Spark Plug Socket Anatomy
A spark plug socket consists of two main parts:
3.1. Socket Size:
- This refers to the diameter of the socket’s opening, which must match the diameter of the spark plug’s hex.
- Common sizes include 5/8 inch (16mm), 13/16 inch (21mm), and 7/8 inch (22mm).
3.2. Drive Size:
- This refers to the size of the square or hex opening on the socket that fits onto your wrench or ratchet.
- The most common drive size is 3/8 inch, but 1/2 inch drives are also available.
4. Common Spark Plug Socket Sizes for Toro Lawn Mowers
While a 5/8 inch (16mm) socket with a 3/8-inch drive is the most prevalent, Toro lawn mowers do come with various engine sizes, and their specific spark plug requirements might differ.
Here are a few examples:
- Toro TimeCutter Mowers: Typically use 5/8 inch (16mm) spark plugs, requiring a 5/8 inch socket.
- Toro Super Recycler Mowers: Also often utilize 5/8 inch (16mm) spark plugs.
- Toro Personal Pace Mowers: May vary in their spark plug size, so checking the owner’s manual is essential.
Choosing the Right Spark Plug Socket
With the knowledge of your Toro lawn mower’s specific spark plug size and the anatomy of a spark plug socket, you can now make a confident purchase.
1. Prioritize Quality and Durability
- Choose a socket made from high-quality steel, which will resist wear and tear.
- Look for sockets that have a deep well to ensure the spark plug fits snugly.
2. Opt for a Set or Individual Socket?
- Sets: Offer multiple socket sizes, providing flexibility for future maintenance tasks.
- Individual Sockets: Are more affordable and ideal if you only need a specific size.
3. Consider Your Tool Collection
- Wrench or Ratchet: Ensure the drive size of the socket you choose is compatible with the tools you have.
Conclusion: Finding the Right Spark Plug Socket for Your Toro Lawn Mower
Finding the perfect spark plug socket for your Toro lawn mower involves a simple process of checking your owner’s manual or inspecting the spark plug itself.

FAQs
What size spark plug socket do I need for my Toro lawn mower?
The size of the spark plug socket you need for your Toro lawn mower depends on the specific model of your mower. Most Toro lawn mowers use a 5/8-inch spark plug socket, but some models may require a different size. You can find the correct size listed in your owner’s manual or by contacting Toro customer support.
If you are unsure of the correct size, it is always best to err on the side of caution and purchase a 5/8-inch spark plug socket. This socket will fit most Toro lawn mowers, and it is readily available at most hardware stores and auto parts stores.
Where can I find the spark plug socket size in my owner’s manual?
The spark plug socket size is typically listed in the maintenance section of your Toro lawn mower owner’s manual. Look for a section that describes how to change the spark plug or perform other maintenance tasks. The spark plug socket size will be listed alongside the other tools you will need.
If you can’t find the information in your owner’s manual, you can download a copy of the manual from the Toro website. You can also contact Toro customer support for assistance.
What if I don’t have my owner’s manual?
If you don’t have your owner’s manual, you can still find the spark plug socket size you need by looking at the spark plug itself. The spark plug will have a size stamped on its side. This size will typically be followed by a letter, which indicates the thread type. For example, a spark plug with the size 5/8-18 would require a 5/8-inch spark plug socket.
If you cannot find the size on the spark plug, you can also take it to a local hardware store or auto parts store and have them help you find the correct size socket.
Are there different types of spark plug sockets?
Yes, there are different types of spark plug sockets, but the most common type is the standard hex socket. This type of socket has a six-sided opening that fits snugly over the hexagonal head of the spark plug. There are also other types of sockets, such as deep sockets and universal sockets, but these are not as common for lawn mowers.
When choosing a spark plug socket, it is important to make sure it is the right size and type for your spark plug. If you are unsure, it is best to consult with a mechanic or an auto parts store employee.
What are some tips for using a spark plug socket?
When using a spark plug socket, it is important to use the correct size and type of socket. You should also make sure that the socket is properly secured to the spark plug before attempting to loosen or tighten it.
Additionally, it is important to avoid using excessive force when tightening the spark plug. Overtightening the spark plug can damage the threads or even crack the spark plug itself.
How do I know if I’m using the right spark plug socket size?
If you are using the correct spark plug socket size, the socket will fit snugly over the spark plug without any play. The socket should also allow you to easily loosen or tighten the spark plug without any difficulty.
If the socket is too small, it will not fit over the spark plug properly, and if it is too large, it may damage the spark plug threads.
What if the spark plug is too tight to remove?
If the spark plug is too tight to remove, you can try using a breaker bar. A breaker bar is a long, heavy bar that is used to increase the leverage you have when loosening a bolt or nut.
You can also try using a spark plug socket wrench, which is a special type of wrench that is designed for loosening spark plugs. If you are still unable to remove the spark plug, you may need to take your lawn mower to a mechanic.
