You’re ready to tackle that overgrown lawn, but when you pull the starter cord, nothing happens. You hear a faint grinding, and then a dreaded silence. The string on your weed trimmer is stuck, refusing to feed. Frustration sets in, leaving you wondering, “Why is my lawn mower string stuck?” This article will explore the common culprits behind a stuck lawn mower string, offering solutions to get you back to mowing in no time.
The most common reasons for a stuck lawn mower string include:
- Worn or damaged string: Over time, the string can become worn, frayed, or tangled, preventing it from feeding properly.
- Clogged or obstructed feed mechanism: Debris, dirt, or grass clippings can clog the string feed mechanism, hindering its ability to release fresh string.
- Damaged or worn spool: The spool itself can become damaged or worn, making it difficult for the string to unwind.
- Loose or damaged spring: The spring that helps advance the string can become weak or break, preventing it from feeding correctly.
Let’s delve deeper into each of these potential problems and how to resolve them.
String-Related Issues
Worn or Damaged String
The most straightforward reason for a stuck string is simply that it’s worn out. Over time, the string can become frayed, brittle, or even break. This can happen due to constant friction against the ground, contact with rocks or other debris, or simply from general wear and tear.
Solution:
- Replace the String: The first step is to remove the old string and replace it with new, high-quality string. Ensure you’re using the correct type of string for your trimmer (round, square, or twisted).
Tip: Always use a string specifically designed for your lawnmower type. Using the wrong type can damage the trimmer’s feed system.
String Tangled or Wound Too Tight
Another common reason for a stuck string is that it’s tangled or wound too tightly on the spool. If the string isn’t properly wound, it can become jammed or knot up, preventing it from feeding out.
Solution:
- Inspect the Spool: Carefully inspect the spool to see if the string is tangled. If it is, you’ll need to untangle it.
- Rewind the String: If the string is wound too tightly, you may need to unwind it slightly and then rewind it more loosely. Be sure to follow the instructions in your owner’s manual for proper string winding.
Tip: When winding the string, avoid winding it too tightly. Allow a slight slack in the string for smooth feeding.
Feed Mechanism Problems
Clogged Feed Mechanism
The string feed mechanism can become clogged with debris, grass clippings, or dirt, preventing it from releasing fresh string. This is a common problem, especially if you haven’t cleaned your trimmer recently.
Solution:
- Clean the Feed Mechanism: Carefully remove any debris, dirt, or grass clippings from the feed mechanism. You can use a small brush or a compressed air can to blow out any debris.
- Check for Obstructions: Inspect the feed mechanism for any other obstructions, such as bent or broken parts.
Tip: Regularly clean your trimmer’s feed mechanism to prevent clogging and ensure smooth string operation.
Damaged or Worn Feed Mechanism
If the string feed mechanism is damaged or worn, it may not function properly. This can be caused by wear and tear over time, or by using the wrong type of string.
Solution:
- Inspect the Feed Mechanism: Carefully inspect the feed mechanism for any signs of damage or wear. Look for bent or broken parts, worn gears, or a damaged spring.
- Replace Damaged Parts: If you find any damaged parts, they need to be replaced. It’s best to consult your owner’s manual or contact the manufacturer for the correct replacement parts.
Tip: If the feed mechanism is severely damaged, it may be best to take it to a qualified repair shop for professional repair.
Spool and Spring Issues
Damaged or Worn Spool
The spool itself can become damaged or worn, making it difficult for the string to unwind. This can be caused by wear and tear over time, or by using the wrong type of string.
Solution:
- Inspect the Spool: Carefully inspect the spool for any signs of damage or wear. Look for cracks, scratches, or a worn-out center spindle.
- Replace the Spool: If the spool is damaged, it needs to be replaced. You can purchase a new spool from your local hardware store or online retailer.
Tip: Always use a spool that’s designed for your specific lawnmower model.
Loose or Damaged Spring
The spring that helps advance the string can become weak or break, preventing it from feeding correctly.
Solution:
- Check the Spring Tension: Inspect the spring to see if it’s weak or broken.
- Replace the Spring: If the spring is broken or weak, it needs to be replaced.
Tip: Be sure to use a spring that’s specifically designed for your lawnmower model.
Other Possible Causes
- Overfilling the Spool: Filling the spool with too much string can cause it to bind and jam.
- Improper String Installation: If the string is installed incorrectly, it may not feed properly. Always refer to the owner’s manual for proper installation instructions.
- Using the Wrong Type of String: Using the wrong type of string can damage the trimmer’s feed system and lead to jamming.
Tip: If you’re still having trouble with your lawnmower string, it’s best to contact a qualified repair shop for professional assistance.
Preventing String Jams
- Regularly Clean Your Trimmer: Clean your trimmer’s feed mechanism regularly to prevent clogging.
- Use the Right Type of String: Always use the type of string that’s recommended for your trimmer.
- Don’t Overfill the Spool: Only fill the spool with the amount of string that’s recommended in the owner’s manual.
- Install the String Correctly: Follow the instructions in the owner’s manual for proper string installation.
By understanding the common causes of a stuck lawn mower string and implementing these simple solutions and preventive measures, you can keep your trimmer running smoothly and efficiently, ensuring a clean and manicured lawn every time.
FAQs
Q1: Why is my lawn mower string stuck in the first place?

This can happen for a few reasons, including using the wrong type of string, not feeding the string correctly, or even just bumping the mower against an object while in use. Another possibility is that the string has gotten too long and is binding against the housing.
If you have any cuts or abrasions on the string, this could also cause it to become stuck. Make sure to use the recommended type of string for your mower and ensure you’re using the correct feeding method. Take care when mowing around objects, and make sure the string is the correct length.
Q2: How do I get the string unstuck?
The first step is to unplug or disconnect the mower from its power source. Then, you’ll need to locate the string cover and carefully remove it. Once the cover is off, you can inspect the string and see what’s causing it to get stuck.
If the string is tangled, you can carefully try to untangle it with your fingers. If the string is too long, you’ll need to cut it back to the correct length. If the string is wrapped around the spool, you may need to use a small screwdriver or other tool to help get it unwound.
