The warm weather is finally here, and you’re ready to tackle your overgrown lawn. But when you grab your trusty string trimmer, you find yourself pulling, pulling, and pulling… with nothing happening. The string just won’t feed! This frustrating experience is all too familiar for many lawn care enthusiasts. So, why is your lawn mower string not pulling?
This article will explore the common culprits behind a stubborn string trimmer, providing you with a comprehensive troubleshooting guide. We’ll cover everything from basic checks to more complex issues, helping you diagnose and fix the problem quickly and efficiently.
A Brief Overview
The most common reasons your lawn mower string won’t pull are:
- The spool is empty: This seems obvious, but it’s easy to forget, especially if you haven’t used the trimmer in a while.
- The string is tangled: A tangled string can prevent it from feeding properly.
- The auto-feed mechanism is jammed: Dirt, debris, or wear and tear can hinder the string’s movement.
- The string is too thick: Using string that’s too thick for your trimmer can overload the motor and prevent it from pulling.
- The string isn’t seated correctly: If the string isn’t properly installed, it won’t feed.
Let’s delve deeper into each of these potential problems, offering step-by-step solutions to help you get your trimmer back in working order.
Is There Any String Left?
The first and most obvious reason for a non-feeding string trimmer is a simple lack of string! While it seems obvious, it’s easy to overlook this possibility, especially if you haven’t used the trimmer in a while.
Here’s how to check:
- Look at the spool: Examine the spool to see if there’s any string remaining.
- Check the trimmer head: If you see a small hole in the trimmer head, this is where the string should be feeding out. Look closely to see if there’s any string visible.
Solution: If you’ve run out of string, simply reload the spool with new string, following the instructions provided in your trimmer’s manual.
A Tangled Mess: The String Is Not Feeding
A tangled string is another common culprit for a non-feeding trimmer. The string can become tangled inside the spool, preventing it from feeding properly.
How to identify a tangle:
- Listen closely: You may hear a grinding or clicking sound when you try to pull the string, indicating that it’s caught.
- Visual inspection: If you can see the string coming out of the trimmer head, look for any knots or twists in the string.
Solutions:
- Remove the spool: Carefully detach the spool from the trimmer head.
- Untangle the string: Use your fingers or a small tool to carefully untangle the string.
- Rewind the spool: Carefully rewind the untangled string onto the spool, ensuring it’s evenly distributed.
- Reinstall the spool: Reattach the spool to the trimmer head, making sure it’s securely fastened.
Stuck in the Middle: The Auto-Feed Mechanism is Jammed
The auto-feed mechanism relies on a simple yet effective design to release the string as needed. However, dirt, debris, or wear and tear can cause this mechanism to jam, preventing the string from feeding.
Signs of a jammed auto-feed mechanism:
- Inability to pull out the string: The string feels stuck, and you can’t pull it out with the trigger.
- A grinding or clicking sound: You may hear a noise when you try to pull the string, indicating a jam.
Solutions:
- Clean the trimmer head: Use a small brush or compressed air to remove any dirt or debris that may be blocking the auto-feed mechanism.
- Check the string: Ensure the string isn’t too thick or too thin.
- Lubricate the mechanism: Apply a small amount of lubricant to the moving parts of the auto-feed mechanism, but avoid excessive lubrication.
- Replace the auto-feed mechanism: If the mechanism is worn out or damaged, replace it with a new one.
String Too Thick: It’s a Weighty Issue
Choosing the right string thickness is crucial for optimal performance. Using a string that’s too thick for your trimmer can overload the motor and hinder the auto-feed mechanism.
How to know if your string is too thick:
- Difficulty pulling: You may find it difficult to pull the string out, and it may feed unevenly.
- Overheating: The motor may overheat quickly, causing the trimmer to shut off prematurely.
- Motor stalling: The motor may stall or struggle to maintain speed when cutting.
Solutions:
- Check your trimmer’s manual: Consult your trimmer’s manual for the recommended string thickness.
- Use the correct string: Replace the thick string with a string that’s appropriate for your trimmer.
Improper Installation: The String Isn’t Seated Correctly
If the string isn’t properly seated in the spool or trimmer head, it won’t feed correctly. The string needs to be securely wound onto the spool and properly aligned within the trimmer head.
Signs of improper string installation:
- The string doesn’t feed evenly: The string feeds out unevenly or in short bursts.
- The string gets caught: The string gets caught or jams inside the trimmer head.
Solutions:
- Check the trimmer’s manual: Refer to your trimmer’s manual for detailed instructions on how to properly install the string.
- Ensure the string is properly seated: Make sure the string is tightly wound onto the spool and properly aligned within the trimmer head.
- Replace the string: If the string is damaged or worn out, replace it with a new string.
The Ultimate Troubleshooting Guide: The Complete Checklist
- Check the spool for string: Is it empty?
- Untangle the string: Is the string knotted or tangled?
- Clean the auto-feed mechanism: Is there any dirt or debris blocking the mechanism?
- Ensure correct string thickness: Is the string too thick for your trimmer?
- Check string installation: Is the string properly seated in the spool and trimmer head?

FAQ
Here are some common reasons why your lawn mower string might not pull, along with solutions:
1. Is the String Worn Out?
Answer: The most common reason your lawn mower string might not pull is that it’s simply worn out. Over time, the string can become frayed or damaged, making it difficult for the pull mechanism to engage. To check, inspect the string for any signs of wear or tear. If it’s worn, you’ll need to replace it with a new one, ensuring you’re using the correct type and diameter for your model.
Solution: Replace the worn string with a new one, making sure it’s the correct type and diameter for your lawn mower. You can find replacement string at most hardware stores or online.
2. Is the Spool Empty?
Answer: Just like a pen needs ink, your lawn mower needs string to work. If the spool is empty, the pull mechanism won’t have anything to engage with. To check, look through the opening in the mower head. If you can’t see any string, it’s time to replace the spool or reload it with new string.
Solution: If the spool is empty, reload it with new string or replace it entirely. You can find instructions on how to replace the spool or reload it with new string in your lawnmower’s user manual.
3. Is the String Jammed?
Answer: Sometimes, the string can become tangled or jammed inside the mower head, preventing it from pulling out. This can be caused by hitting obstacles like rocks or branches, or by the string getting wrapped around the spindle. To check for a jam, gently pull the string to see if it moves freely. If it feels stuck, you’ll need to untangle or remove the jammed string.
Solution: If the string is jammed, carefully try to untangle it with a small tool or your fingers. If you can’t untangle it, you may need to remove the spool and clear the jam from the inside. Refer to your lawnmower’s manual for specific instructions.
4. Is the Pull Mechanism Broken?
Answer: While less common, it’s possible that the pull mechanism itself is broken. This can be caused by overuse, wear and tear, or even a manufacturing defect. If you suspect a broken pull mechanism, you’ll likely need to contact the manufacturer or a qualified repair technician.
Solution: If you suspect a broken pull mechanism, contact the manufacturer or a qualified repair technician for assistance. They will be able to diagnose the problem and provide the necessary repairs.
5. Is the Spring Tension Incorrect?
Answer: The spring inside the pull mechanism provides tension to help the string retract properly. If the spring tension is too loose or too tight, it can prevent the string from pulling out smoothly. To adjust the tension, you’ll need to access the spring and make adjustments according to your lawnmower’s user manual.
Solution: Adjust the spring tension according to the instructions in your lawnmower’s user manual. Be careful not to overtighten the spring, as this can damage the pull mechanism.
6. Is the String Guide Broken?
Answer: The string guide helps direct the string as it feeds out of the spool. If the string guide is broken or damaged, it can prevent the string from pulling out properly. You can check the string guide by looking for cracks or other damage.
Solution: If the string guide is broken or damaged, you will need to replace it with a new one. You can find replacement string guides at most hardware stores or online.
7. Is the Mower Head Stuck?
Answer: Occasionally, the mower head itself can become stuck, preventing the string from pulling out. This might happen due to debris build-up or a mechanical issue. To check, try to move the mower head back and forth. If it’s stuck, you’ll need to investigate further to identify the cause and try to free it.
Solution: If the mower head is stuck, remove any debris blocking it and try to free it by gently moving it back and forth. If it remains stuck, consult your lawnmower’s manual or contact a repair technician.
