Keeping your yard in tip-top shape requires the right tools. A lawn trimmer is essential for keeping those edges neat and tidy. However, if your trimmer isn’t performing like it used to, it might be time to replace the trimmer line. Don’t worry—replacing the string in your lawn trimmer is a simple task that you can handle with just a few tools and a bit of Kenyon Noble Know-How.

Tools You’ll Need
Before diving into the project, make sure you have everything you need on hand:
- Lawn trimmer with the battery removed or unplugged for safety)
- Scissors
- Replacement trimmer line

At Kenyon Noble, we stock a variety of trimmer lines to fit different models, ensuring you can find exactly what you need. Our friendly staff is always available to help you select the right line for your trimmer.
Step 1: Prepare Your Trimmer
Before you start, ensure your trimmer is completely powered down. If it’s battery-operated, remove the battery. If it’s corded, make sure it’s unplugged. This precaution is crucial for your safety.
Know-How Tip: Safety first! Always double-check that your trimmer is powered down before beginning any maintenance.

Step 2: Remove the Spool
To access the trimmer line, you’ll need to remove the spool. Depending on your trimmer model, you may need to press tabs or unscrew the spool cap. Consult your trimmer’s user manual if you’re unsure of how to remove the spool cap. Once the cap is off, gently pull out the spool from the trimmer head.
Know-How Tip: Keep the spool cap and any small components in a safe spot while you work. These pieces are easy to misplace!

Step 3: Prepare the Replacement Line
Next, cut a length of replacement trimmer line according to your trimmer’s specifications. Typically, this will be between 20 to 25 feet, depending on your model. Refer to your trimmer’s manual to determine the exact length required.
Know-How Tip: It’s better to cut a little extra line than to cut too short. You can always trim it down later if needed.

Step 4: Wind and Secure the Line
Now, find the anchor hole on the spool and insert one end of the line. Begin winding the line tightly and evenly around the spool in the direction indicated by the arrows on the spool. Leave about 6 inches of line free at the end, and secure the loose ends in the notches on the spool.
Know-How Tip: Wind the line carefully and evenly. A tangled or unevenly wound line can cause the trimmer to jam or operate inefficiently.

Step 5: Reassemble the Trimmer Head
With the line securely wound, place the spool back into the trimmer head. Thread the ends of the line through the eyelets on the trimmer head, and then secure the spool cap back onto the trimmer.
Know-How Tip: Make sure the line passes smoothly through the eyelets without catching or snagging. This will ensure a smooth operation when you start trimming.

Step 6: Test the Trimmer
Finally, reattach the battery or plug in your trimmer and give it a test run. The new line should slice through grass and weeds with ease.
Know-How Tip: Regularly inspect your trimmer line and replace it as soon as you notice it wearing down.

Wrapping It Up
And that’s all there is to it! With a fresh trimmer line installed, your lawn trimmer should be ready to tackle your yard work with renewed vigor. Regular maintenance like this not only extends the life of your trimmer but also ensures your yard always looks its best.
