A Quick Overview of Replacing Lawn Mower String
Changing a lawn mower string is a straightforward process that requires minimal tools and effort. It typically involves removing the old string, installing a new spool of string, and adjusting the string length. This article provides a detailed breakdown of each step, offering valuable tips and tricks for a successful string replacement.
Identifying When Your Lawn Mower String Needs Replacing
Before diving into the replacement process, it’s crucial to recognize when your lawn mower string requires attention. Here are some telltale signs:
1. The Mower is Losing Power
If your lawn mower starts struggling to cut grass or makes a high-pitched whining sound, the string might be worn down or tangled. This indicates it’s time for a replacement.
2. The String is Visible
The string housing on your mower should have a small opening to reveal the string. If you notice the string is significantly shorter or frayed, it’s time for a fresh spool.
3. You’re Having Trouble Cutting Grass
If your mower is skipping over grass or leaving uneven cuts, it could be due to a worn string. A new string will ensure a clean and precise cut.
Choosing the Right String for Your Lawn Mower
Not all lawn mower strings are created equal. Understanding the different types will help you pick the right one for your needs:
1. Round String
Round string is the most common type, offering a balance of durability and cutting performance. It’s suitable for most lawn types and can be found in various materials like nylon, polymer, and composite blends.
2. Square String
Square string provides a more aggressive cut, ideal for thicker weeds and tough grasses. It’s also known for its longer lifespan compared to round string.
3. Triangular String
This unique string shape offers a combination of cutting power and durability, making it a good all-around option. It can be particularly useful for tackling stubborn weeds and thick vegetation.
4. Premium Strings
Several premium strings are designed with specialized features, such as anti-vibration technology, enhanced durability, or specific blade configurations for specific lawn types. These options may offer improved performance and a longer lifespan but come at a higher cost.
Essential Tools for Changing Your Lawn Mower String
Before you begin, gather the necessary tools:
- A new spool of string: Choose the type and size compatible with your mower.

Step-by-Step Guide to Replacing Lawn Mower String
Now that you have your tools and new string, follow these steps to replace your lawn mower string:
1. Turn Off the Mower and Disconnect the Spark Plug Wire
Ensure the engine is completely off and disconnected from the spark plug. This safety precaution prevents accidental starting while you work.
2. Remove the String Housing
Locate the string housing on your lawn mower. It’s usually located at the bottom, beneath the cutting deck. Remove the screws securing the housing using your Phillips-head screwdriver.
3. Remove the Old String Spool
Once the housing is off, remove the old string spool. This can be done by simply pulling it out or releasing a locking mechanism, depending on your mower’s model.
4. Load the New String Spool
Carefully insert the new spool of string into the housing. Make sure the string is feeding out correctly through the slots or holes in the housing.
5. Tighten the String Spool
Use pliers to tighten the spool securely into the housing. This ensures the string will feed out smoothly and doesn’t get tangled.
6. Replace the String Housing
Reinstall the string housing on the mower and secure it with the screws you removed earlier.
7. Cut the String to the Correct Length
Use scissors or a knife to trim the string to the recommended length for your mower model. This information is usually found in your mower’s manual or on the string packaging.
8. Test the String
Before starting the engine, test the string by pulling it out slightly and making sure it’s feeding properly.
9. Start the Mower and Check for Proper Operation
Start the mower and observe the string’s operation. The string should spin freely and cut grass smoothly. If you encounter any issues, recheck the string length and feeding mechanism.
Additional Tips for Replacing Lawn Mower String

FAQ
1. What types of string are compatible with my lawnmower?
The type of string you need will depend on your lawnmower. Most mowers use round string, which is available in different diameters. You can also find square string, which is designed for specific mowers. Check your lawnmower’s manual or the manufacturer’s website for the recommended string type and diameter. If you’re unsure, visiting a local hardware store or garden center can help you find the right string for your model.
If you need to replace the string in a string trimmer, it is important to consider the thickness of the line and the shape of the spool. Round line is available in various thicknesses, and there are also square lines designed for certain types of string trimmers. You should always refer to your manufacturer’s manual for the proper string type and thickness to ensure that the trimmer is functioning correctly.
2. What tools do I need to change the lawnmower string?
You won’t need a lot of tools to change your lawnmower string. You’ll need a screwdriver (usually a Phillips head) to access the string housing, a pair of pliers or a string winder to help you load the string, and a pair of scissors or a knife to cut the string to the appropriate length. You may also need a small brush or cloth to clean the string housing of any debris or grass clippings that could interfere with the process.
While changing the string may seem simple, it’s important to have the right tools on hand. Ensure that your screwdriver fits the screws on the string housing, and that your pliers or string winder are the correct size for the spool. Having the right tools can make the process easier and safer, as well as ensure that your lawnmower is properly assembled and functions correctly.
3. How do I know when to replace the lawnmower string?
You’ll know it’s time to replace your lawnmower string when the string gets worn down or breaks. You can also tell by the sound of your mower. If it’s making a “clinking” or “thumping” sound, this could indicate that the string is hitting the housing. It’s also a good idea to inspect the string regularly for any signs of damage, such as fraying or breakage.
You should also consider replacing the string if you notice that your lawnmower is no longer cutting grass as effectively. This could be a sign that the string is not long enough or that it is not sharp enough. Regularly replacing the string ensures that your lawnmower is functioning at its best and that you are able to achieve a clean and precise cut.
4. How do I load the string into the lawnmower?
The process of loading string into a lawnmower can vary slightly depending on the model. However, the general steps involve first removing the spool cover, which is usually held in place by a few screws. Then, you will need to remove any old string from the spool. To load the new string, thread it through the spool’s center hole, looping it around the spool a few times. You may need to use a string winder to help keep the string taut and prevent it from tangling as you wind it around the spool. Finally, you can close the spool cover and secure it with the screws.
Always check your lawnmower’s manual for the specific instructions for your model. It will provide detailed illustrations and explanations for the loading process, ensuring that you are properly winding the string and preventing any potential damage to the spool or the housing.
5. How much string should I use?
The amount of string you need to use will depend on the size of your spool and the length of the string. It’s best to follow the instructions in your lawnmower’s manual, but in general, you’ll want to leave about an inch of string sticking out from the bottom of the spool.
It is essential to ensure that you are not overfilling the spool, as this can cause the string to become tangled or even break. Always check your manual for the recommended length of string to use. Over-winding the spool can also cause the string to become too thick, leading to uneven cutting and even damage to your lawnmower.
6. How do I properly cut the string?
Once you’ve loaded the string, you’ll need to cut it to the appropriate length. It’s essential to use a sharp blade to ensure a clean cut. Always cut the string at a 45-degree angle to prevent it from fraying. A sharp blade will also help prevent the string from becoming dull too quickly, which can impact the effectiveness of your lawnmower.
It’s best to trim a small amount of string at a time to ensure you don’t cut it too short. Too much string can tangle or become too long, leading to uneven cutting.
7. What are some safety tips for changing the lawnmower string?
Before changing the string, always unplug the lawnmower or disconnect the spark plug to prevent accidental starting. You should also wear eye protection and gloves to protect yourself from potential injuries. When handling the string, avoid cutting it too short, as this can result in a sharp edge that could cause injury.
Be careful when using tools, and avoid applying too much pressure. If you have any doubts, consult the lawnmower’s manual or seek help from a professional. Remember that safety should always come first. Taking precautions and following safety guidelines can ensure that you change the string safely and efficiently.
