A weed eater—also called a string trimmer or weed whacker—is one of the most versatile tools for lawn maintenance. But what happens when the cutting string runs out, the head breaks, or a replacement spool isn’t available? Some creative homeowners have found an unconventional fix:
zip ties.
Using zip ties on a weed eater might seem like a quick and clever solution. After all, they’re strong, flexible, and easy to attach. But can you really use zip ties safely and effectively on a weed eater?
In this article, we’ll break down whether
zip ties can work as a trimmer line substitute, when it’s okay to use them, what the risks are, and how to use them properly if you're in a pinch.
What Are Zip Ties, and Why Do People Use Them for Weed Eaters?
Zip ties, also known as cable ties, are made from nylon and are commonly used to bundle wires, fasten components, or temporarily repair items. They are:
Because of these qualities, zip ties are sometimes used by DIYers as an
emergency substitute for trimmer string on a weed eater. When the proper line isn’t available, people have discovered that
a few strong zip ties can cut grass and even light weeds when spun at high speed.
Can You Replace the Trimmer Line with Zip Ties?

Yes—but only for light-duty, short-term use.
Zip ties can spin fast enough in some weed eaters to mimic the motion of real trimmer string. They can cut grass, light weeds, and small patches of overgrowth. This makes them a
viable emergency hack, especially if:
- You’re out of the trimmer line
- Your replacement spool doesn’t fit
- You only need to finish a small job
- You’re trimming along fence lines or garden beds
That said,
zip ties are not a permanent replacement. They lack the cutting power, durability, and safety of a proper trimmer line.
The Pros of Using Zip Ties on a Weed Eater
If you decide to try zip ties as a weed eater fix, there are a few benefits to consider:
1. Convenience
You can find zip ties in almost any hardware drawer, toolbox, or garage. If your string breaks mid-job, zip ties let you finish the task without having to drive to the store.
2. Affordability
A 100-pack of zip ties can cost less than a single replacement spool. For budget-conscious homeowners, it’s an easy fix.
3. Ease of Use
No rewinding or complicated installation. Just drill two holes in the trimmer head, insert the zip ties, and tighten.
4. Creative Freedom
Some users experiment with different lengths, weights, and materials to handle specific weeds or lawn conditions. While this isn’t recommended for everyone, DIYers enjoy testing what works best in their yard.
The Cons and Risks of Using Zip Ties on a Weed Eater
While zip ties may work for light trimming, they come with significant drawbacks and safety concerns:
1. Lack of Flexibility
The trimmer line is designed to flex and whip through grass. Zip ties are stiffer, which means they:
- Can’t curve around obstacles easily
- Are more likely to snap under pressure
- May deliver inconsistent cutting results
2. Quick Wear and Breakage
Zip ties were never meant to spin at high RPMs. They wear down faster, especially when hitting rocks, fences, or thick stems. Some may break within minutes.
3. Safety Hazards
When a zip tie breaks at high speed, it can become a flying projectile. Unlike trimmer line, which shreds harmlessly, a broken zip tie can:
- Damage windows
- Chip paint
- Injure people or pets nearby
Always wear safety glasses and full protective gear if you plan to test this method.
4. Motor Damage Risk
Heavier zip ties may put more strain on the weed eater’s motor. Over time, this can cause the motor to overheat, wear out the bearings, or unbalance the spinning head.
5. Void Manufacturer Warranty
Using anything other than the proven trimmer line may void your warranty. Manufacturers design their tools to work with specific sizes and shapes of line—not zip ties.
How to Attach Zip Ties to a Weed Eater (If You Must)
If you're in a bind and decide to give it a try, here’s a basic guide to using zip ties as a temporary trimmer string.
What You’ll Need:
- Heavy-duty zip ties (at least 8" long and 0.2" wide)
- A drill (optional)
- Safety goggles and gloves
Step-by-Step:
-
Turn off and unplug your weed eater. Remove the battery if it’s cordless.
-
Remove the current trimmer head. If you’re using a spool-based model, empty it out or remove the head entirely.
-
Drill two small holes opposite each other on the trimmer hub or cap (if it allows).
-
Insert one zip tie through each hole, locking it so that about 6 inches stick out on each side.
-
Tighten the zip tie and trim the tail, leaving just the loop exposed.
-
Test the balance. Spin the head slowly by hand. If it wobbles, reposition the ties to even the weight.
-
Run the weed eater at low speed to check performance before going full throttle.
Best Practices and Safety Tips
-
Use short bursts instead of running the motor continuously.
-
Check frequently for wear—replace zip ties at the first sign of fraying.
- Don’t use gravel, metal edging, or concrete.
-
Never use metal zip ties or reinforced ties—they can cause serious injuries or equipment damage.
-
Keep children and pets indoors while you test this setup.
This method is best used to finish a job you’ve already started—not for routine lawn care.
Better Alternatives to Zip Ties for Weed Eater Repairs
While zip ties can work temporarily, there are better long-term options:
✅ 1. Pre-Cut Trimmer Blades
Some models accept solid plastic or nylon
trimmer blades, which are easier to install and last longer than string. They’re also designed for safe rotation.
✅ 2. Twist-and-Feed Replacement Heads
Universal trimmer heads allow you to load short pieces of line without needing a spool. These are ideal for homeowners who don’t want to deal with rewinding string.
✅ 3. Pivoting String Heads
These use flexible line attachments that pivot on impact, reducing breakage and wear. They work better around fences and concrete.
✅ 4. Manufacturer Replacement Line
When possible, stick to the correct line size and shape recommended by your trimmer’s brand. Using the right line prevents damage, extends tool life, and ensures clean cuts.
Final Verdict: Can You Use Zip Ties on a Weed Eater?
Yes—you can use zip ties on a weed eater in an emergency, but it’s not a recommended long-term solution. Zip ties can substitute for trimmer lines when you're in a pinch, but they come with risks, wear down quickly, and may damage your tool if misused.
If you choose to try this method:
- Use it only for light-duty tasks
- Follow all safety precautions
- Don’t use it near people, pets, or property
- Replace with the proper line as soon as possible
For routine lawn maintenance, invest in a proper line or upgrade to a trimmer head that’s easier to manage. Zip ties may save the day once, but they’re not designed for life on the lawn.
