Understanding Your Trimmer Head
Before we jump into the steps, let’s take a moment to understand the different types of trimmer heads you might find on your lawnmower. The most common types are:
- Automatic Feed Heads: These heads feature a spool that automatically feeds out string as you use it. You typically just need to bump the head on the ground to release more string.
- Manual Feed Heads: These heads require you to manually advance the string by rotating a knob or lever.
Knowing the type of head you have is important because the method for loading and replacing the string will vary slightly depending on the design.
Replacing the String on an Automatic Feed Head
Automatic feed heads are designed for convenience and simplicity. Here’s how to replace the string on this type of head:
Step 1: Gather Your Supplies
Before you begin, gather the following supplies:
- New trimmer line: Make sure you choose the right diameter and type of string for your lawnmower. Check your owner’s manual for recommendations.
- Gloves: These are optional, but recommended for protecting your hands from sharp edges.
- A pair of pliers (optional): You may need pliers to remove the spool if it is stuck.
Step 2: Disassemble the Trimmer Head
To access the spool, you’ll need to disassemble the trimmer head. This usually involves:
- Releasing the cover: Look for a button or latch that secures the cover to the trimmer head. Press the button or lift the latch to release the cover.
- Removing the cover: Gently pull the cover off the trimmer head, exposing the spool.
Step 3: Loading the New String
Now, it’s time to load the new string onto the spool.
- Cut the string: Measure and cut the new string to the appropriate length. Most automatic feed heads have markings on the spool indicating the correct length.
- Wind the string: Wind the string onto the spool in the direction indicated by an arrow or a mark on the spool. Make sure the string is wound tightly and evenly.
- Secure the string: Some spools have a small tab or clip to hold the end of the string in place. Others may require a small piece of tape.
Step 4: Reassemble the Trimmer Head
Once the new string is loaded, you can reassemble the trimmer head:
- Replace the cover: Align the cover with the trimmer head and push it back into place until it clicks.
- Secure the cover: Make sure the button or latch is engaged to secure the cover.
Step 5: Test Your Lawn Mower
Now, you’re ready to test your lawnmower. Start the engine and carefully test the string trimmer. Make sure the string is feeding out properly and trimming the grass. If the string is not feeding out, check that the string is wound in the correct direction and that it is securely fastened to the spool.
Replacing the String on a Manual Feed Head
Manual feed heads require a little more effort, but the process is still relatively straightforward. Here’s how to replace the string on this type of head:
Step 1: Gather Your Supplies
You’ll need the same supplies as for automatic feed heads:
- New trimmer line: Choose the right diameter and type of string for your lawnmower.
- Gloves: These are optional but recommended for protecting your hands.
- A pair of pliers (optional): You may need pliers to remove the spool if it is stuck.
Step 2: Disassemble the Trimmer Head
Most manual feed heads have a simple design that can be disassembled by hand.
- Locate the release lever: Find the lever or knob that secures the spool to the trimmer head. This is usually located on the side or bottom of the head.
- Release the lever: Push the lever or rotate the knob to release the spool.
- Remove the spool: Gently pull the spool out of the trimmer head.
Step 3: Loading the New String
Once you have removed the spool, it’s time to load the new string:
- Cut the string: Measure and cut the new string to the appropriate length. The spool may have markings to guide you.
- Wind the string: Wind the string onto the spool in the direction indicated by an arrow or a mark on the spool. Make sure the string is wound tightly and evenly.
- Secure the string: Some spools have a small tab or clip to hold the end of the string in place. Others may require a small piece of tape.
Step 4: Reassemble the Trimmer Head
- Replace the spool: Insert the spool back into the trimmer head, aligning the tabs or grooves with the corresponding slots.
- Secure the lever: Push the release lever or rotate the knob to secure the spool.
Step 5: Test Your Lawn Mower
Start the engine and test the string trimmer to ensure the string is feeding out properly. If the string is not feeding out, check that it is wound in the correct direction and that it is securely fastened to the spool.
Troubleshooting Common Problems
Even with the best intentions, you might encounter a few problems when replacing the string on your lawnmower. Here are some common issues and how to resolve them:
1. String Not Feeding Out
- Check the winding direction: Ensure the string is wound in the correct direction. If you have wound the string backwards, it will not feed out properly.
- Secure the string: Make sure the string is securely fastened to the spool. If the string is loose, it may come off the spool during operation.
- Clean the trimmer head: Dirt and debris can interfere with the string feeding mechanism. Clean the trimmer head with a brush or cloth.
2. String Snapping Too Quickly
- Use the correct string diameter: Make sure you are using the correct diameter of string for your lawnmower. Using too thick or too thin of a string can cause it to break easily.
- Check the string quality: Low-quality string is more prone to breaking. Use a high-quality string that is designed for your lawnmower.
- Replace the spool: If the spool is worn or damaged, it can cause the string to break easily. Replace the spool if it is cracked or showing signs of wear.
3. Trimmer Head Jamming
- Clear the trimmer head: If the trimmer head is jammed, gently remove any debris that may be blocking the string from feeding.
- Check for damage: If there is damage to the trimmer head, replace the head or consult a professional.

FAQs
What type of string is best for my lawnmower?
The best string for your lawnmower depends on the type of grass you have and the terrain you’re mowing. For standard lawns with a mix of grasses, a round line made of nylon or polypropylene is generally a good choice. If you have tougher weeds or thick grasses, you might consider a square or star-shaped line, which offers better cutting power.
Always refer to your lawnmower’s manual for recommendations on string diameter and type. Using the wrong type of string can damage your mower or lead to poor cutting performance.
How often should I change my lawnmower string?
You should change your lawnmower string when it gets worn down or frayed. This will typically happen after several mowing sessions, depending on the type of grass you’re cutting, the length of the string, and how frequently you use your mower.
Keep an eye on the string as you mow. If it starts to make a rattling or scraping noise, or if you notice it’s not cutting the grass cleanly, it’s time for a replacement.
Can I change the string on any lawnmower?
Not all lawnmowers use string. Some models, especially those designed for thick grass or tough weeds, use blades. If your lawnmower has a round or rectangular opening on the bottom, it’s likely a string trimmer. However, if you have a different type of lawnmower, you’ll need to consult your manual to determine the proper replacement method.
Changing the string on a string trimmer is generally a straightforward process. Most mowers have a simple system that allows you to manually load and release the string.
What tools do I need to change the lawnmower string?
You won’t need many tools to change your lawnmower string. The most important is a spool of new string that is compatible with your mower. You may also need a pair of scissors or a utility knife to cut the string to the appropriate length.
Some string trimmers have an automatic string-feeding system, which makes changing the string even easier. If your mower has this feature, you won’t need any additional tools.
What if I can’t get the old string out?
If you’re having trouble removing the old string, there are a few things you can try. First, check your lawnmower’s manual for instructions on how to access and remove the string. If that doesn’t work, you can try using a small screwdriver or pliers to help loosen the string.
If you’re still having trouble, it’s best to consult a professional repair service. They can help you remove the old string safely and efficiently.
Is it dangerous to change the string on my lawnmower?
Changing the string on your lawnmower can be a simple and safe process if you follow the proper steps. Make sure to disconnect the spark plug or remove the battery before you begin working on the mower, and be careful not to touch the blades or any moving parts.
Always wear protective gear, such as gloves and safety glasses, while working on your lawnmower.
What are some tips for getting the most out of my lawnmower string?
To get the most out of your lawnmower string, it’s important to use the right type of string for your lawn and mower. Always refer to your lawnmower’s manual for recommendations on string diameter and type.
You should also make sure the string is properly loaded and tensioned. If the string is too loose, it can break or become tangled. If it’s too tight, it can put undue stress on the mower’s motor.
