We’ll cover everything from identifying the problem to replacing the string, and even some tips for preventing future snags. So, grab your tools and let’s get started!
Overview
Lawn mower string problems are usually caused by a broken or worn-out string, or a tangled string within the spool. Identifying the exact issue will determine the best course of action, be it a simple string replacement or a more involved fix. This guide will walk you through the process of diagnosing the problem, understanding the different types of string and spools, and implementing the appropriate repair methods.
Identifying the Problem
The first step is to pinpoint the source of the problem. Is the string simply worn out and needs replacing? Or is there a more complex issue with the spool or the feeding mechanism?
1. Inspect the String
a. Worn String:
Examine the string for any signs of fraying, thinning, or breakage. If the string is worn down, it’s time for a replacement.
b. Tangled String:
If the string seems to be getting stuck or not feeding properly, the string itself may be tangled within the spool. This is a common issue, especially with older or less frequently used mowers.
2. Check the Spool
a. Spool Damage:
If the spool itself is damaged or broken, the string may not be feeding correctly. Inspect the spool for cracks, loose parts, or any signs of wear and tear.
b. Spool Mechanism:
The mechanism that feeds the string from the spool can also malfunction. Check to see if the string is getting caught or if the spool is spinning freely.
Replacing the Lawn Mower String
Once you’ve identified that the string needs replacing, you’ll need the right tools and materials. Here’s what you’ll need:
- New Lawn Mower String: Choose a string that’s compatible with your mower. Look for a string made of durable material like nylon or plastic, and the correct diameter for your spool.
- Screwdriver: You’ll need a screwdriver to access the spool housing.
- Gloves: Protect your hands from sharp string ends.
- Scissors or wire cutters: To cut the new string to the right length.
Step-by-Step Guide:
-
Disengage the Blade: Always disconnect the spark plug wire from the engine and ensure the blade is completely stopped before working on the string.
-
Remove the Spool Housing: Use the screwdriver to loosen and remove the screws holding the spool housing in place. This will give you access to the spool.
-
Remove the Old String: If you are dealing with a tangled mess, gently untangle it as much as possible before removing it from the spool. Use the scissors or wire cutters to cut the string and remove it from the spool.
-
Insert the New String: Wind the new string around the spool, following the direction indicated by arrows on the spool. Ensure the string is tightly wound and does not overlap itself.
-
Attach the String: Most spools have a small hole where you insert the string. Thread the string through the hole and tie a knot at the end.
-
Replace the Spool Housing: Reassemble the spool housing, making sure the screws are securely fastened.
-
Test the String: Before starting the mower, gently pull on the string to ensure it feeds freely. If it does not feed easily, check that the string is correctly wound and that the spool mechanism is working properly.
Troubleshooting Common Problems
Even after replacing the string, you may encounter some problems. Here are some common issues and solutions:
1. String Not Feeding Properly:
- Check the String Tension: Make sure the string is wound tightly on the spool. If it’s too loose, it won’t feed out properly.
- Examine the Spool Mechanism: If the spool mechanism is not working properly, the string may not be able to feed out. Check for any obstructions or damage.
2. String Breaking Frequently:
- Use the Right String Diameter: Make sure you’re using the correct string diameter for your mower.
- Avoid Overloading the String: Do not try to cut through thick weeds or tall grass with a thin string, as this will put too much stress on the string and cause it to break.
Maintaining Your Lawn Mower String
Just like any other part of your lawn mower, the string requires some care and attention to ensure it lasts. Here are some tips for maintaining your lawn mower string:
- Regular Inspection: Check the string frequently for signs of wear or damage. Replace it as needed.
- Clean the Spool: Dirt and debris can accumulate in the spool and cause the string to get tangled. Clean the spool regularly.
- Store Properly: When not in use, store the mower in a dry, clean location. This will help prevent the string from rusting or becoming damaged.
Conclusion
Armed with this information, you can tackle the challenge of a broken or tangled lawn mower string with confidence. Whether you’re replacing a worn-out string or troubleshooting a feeding problem, the steps outlined in this guide will help you get back to enjoying a well-maintained lawn in no time. Remember to always prioritize safety by disconnecting the spark plug and ensuring the blade is stopped before working on any part of the mower.
FAQ
What is a lawnmower string and what is it used for?
A lawnmower string is a thin, durable cord made of nylon or plastic that is used in string trimmers and weed eaters to cut grass and weeds. It’s attached to a spool inside the trimmer head and spins at high speed to trim the grass and weeds. It’s designed to break when it hits something solid, preventing damage to the trimmer or the object it hits.
The string is wound around a spool and fed out of a trimmer head, cutting grass and weeds with a spinning motion. It’s a common tool for trimming around obstacles like trees, fences, and flowerbeds, where a rotary mower can’t reach.
What are the common types of lawnmower strings?
There are two main types of lawnmower strings: round and square. Round string is the most common type and is available in a variety of diameters. Square string is less common but is often used for heavier-duty trimming.
The type of string you choose will depend on the type of trimmer you have and the type of trimming you’ll be doing. Round string is generally best for lighter-duty trimming, while square string is better for heavier-duty trimming or thick weeds.
How do I know when I need to replace my lawnmower string?
You’ll need to replace your lawnmower string when it’s worn down or broken. A worn string will be shorter and thinner than a new string, and it may not be able to cut grass effectively. A broken string will simply stop working altogether.
Another sign that you need to replace your string is if it’s making a lot of noise. A worn string can make a rattling or grinding noise as it spins, and this can be a sign that it’s about to break.
How do I choose the right replacement string?
Choosing the right replacement string is important for getting the best results from your trimmer. The string should be compatible with your trimmer’s head, and it should be the right thickness for the type of trimming you’ll be doing.
You can find replacement string at most hardware stores and home improvement centers. Check the specifications of your trimmer head to determine the correct type and size of string.
What tools do I need to replace the lawnmower string?
Replacing your lawnmower string is a simple task that requires minimal tools. Here’s what you’ll need:
- A new spool of string: Choose the correct type and size of string for your trimmer.
- A pair of pliers: These will be used to help you wind the string onto the spool.
- A small screwdriver: This will be used to loosen and tighten the trimmer head.
With these basic tools, you’ll be able to replace your string quickly and easily.

Following these tips will ensure a smooth and successful replacement process.
What are some common mistakes to avoid when replacing lawnmower string?
While replacing lawnmower string is generally a straightforward process, there are some common mistakes to watch out for:
