Introduction

Worx weed eaters are a top choice for homeowners and professional landscapers alike, thanks to their reliable performance, lightweight design, and innovative features like the patented Worx line feed system. But like all string trimmers, the trimmer line on your Worx model will eventually wear down, break, or run out entirely. When that happens, you don’t need to run to the store for an expensive replacement spool – learning how to Respool Worx Weed Eater? units yourself will save you money, reduce waste, and get your tool back in working order in minutes.

Many Worx owners assume respooling is a complicated, technical process, but it’s actually one of the simplest maintenance tasks you can perform on your outdoor power equipment. Whether you have a corded WG150 model, a cordless WG190, or one of Worx’s popular turbine-head trimmers, the core respooling process is nearly identical across all models. This comprehensive guide walks you through every step of the process, from identifying when you need to respool to choosing the right trimmer line, avoiding common mistakes, and extending the life of your spool for months of reliable use.

By the end of this article, you’ll have all the information you need to tackle this quick maintenance task confidently, no prior experience required.

Understanding Your Worx Weed Eater Spool System

Before you start respooling, it’s helpful to understand how your Worx weed eater’s spool system works. The spool is a small, circular plastic component that holds your trimmer line, and it sits inside a protective housing at the bottom of the weed eater’s cutting head. Most Worx models use a “tap-and-go” or automatic line feed system: when the line wears down to a short length, you tap the bottom of the cutting head on the ground (or press a button on the handle, depending on the model) to release more line from the spool automatically.

The spool housing has a small slot that the line feeds through to extend out of the cutting head, and a line feed mechanism inside the housing that grabs the line and pulls it out when activated. The housing is covered by a removable cap that keeps dirt, grass, and debris out of the internal components. Understanding this basic setup will make the respooling process much easier, as you’ll know exactly how the line feeds through the system and how to align the spool correctly during installation.

Common Worx Spool Types

Worx uses two main types of spools across its weed eater lineup, and the respooling process is slightly different for each:

  • Single-line spools: These are the most common spool type, included with entry-level and mid-range Worx models like the WG150, WG160, and WG170. They hold a single strand of trimmer line, wound in one direction around the center of the spool. Single-line spools are easy to respool and work well for light residential use.
  • Dual-line spools: These spools are included with higher-end Worx turbine-head models, like the WG180 and WG190. They hold two separate strands of trimmer line, wound in opposite directions on either side of the spool. Dual-line spools cut faster and provide better balance for heavy-duty use, but require you to wind two separate pieces of line during respooling.

Some Worx models also use a “rapid reload” spool system that allows you to swap out empty spools in seconds without winding line yourself, but even these models can be respooled manually to save money on replacement spools. Always check your user manual to confirm which type of spool your model uses before starting the respooling process.

Signs You Need to Respool Your Worx Weed Eater

It can be hard to tell exactly when your Worx weed eater needs a new spool of line, especially if you only use it occasionally. Here are the most common signs that it’s time to respool:

  • Line is shorter than 2 inches: Most Worx models require at least 2 inches of line extending from the cutting head to feed properly. If your line is shorter than this, you’ll have to manually pull out line every few seconds while trimming, which is inefficient and can damage the line feed mechanism.
  • Line is frayed, nicked, or broken: Small nicks and frays in the line will cause it to break easily while trimming, and can create sharp edges that damage the spool housing or line feed mechanism. If you notice multiple breaks or fraying along the length of the line, it’s time to replace it.
  • Line feed is not working: If pressing the line feed button or tapping the cutting head on the ground doesn’t release more line, the spool is likely empty, or the line is tangled inside the housing. Before assuming the line feed mechanism is broken, check the spool first – most feed issues are caused by an empty or improperly wound spool, not a mechanical failure.
  • Burning smell while trimming: If you notice a burning plastic smell while using your weed eater, the spool is likely empty, and the motor is working too hard to spin the cutting head with no resistance. Stop using the tool immediately and respool it to avoid damaging the motor.
  • Cutting performance is poor: If your weed eater is struggling to cut through even thin grass, the line is likely worn down to a very short length or is dull from use. Respooling with fresh line will restore cutting performance immediately.

If you notice any of these signs, don’t wait to respool your tool. Continuing to use an empty or worn spool can cause permanent damage to the line feed mechanism or motor, leading to costly repairs down the line.

Tools and Materials You’ll Need for the Job

One of the best things about respooling a Worx weed eater is that you don’t need any special or expensive tools to get the job done. Most of the items you’ll need are likely already in your garage or toolbox. Here’s what to gather before you start:

  • Replacement trimmer line: Make sure to get line that matches the recommended diameter and shape for your specific Worx model. You can buy pre-cut Worx-branded line, or bulk line and cut it to size yourself to save money.
  • Scissors or line cutter: You’ll use this to cut the trimmer line to the correct length for your spool. A sharp pair of scissors works fine, but a dedicated line cutter will give you a clean, even cut that reduces fraying.
  • Small flat-head screwdriver (optional): Most modern Worx models have tool-free spool caps that twist off by hand, but some older or heavy-duty models have a small screw holding the cap in place. If your model has a screw, you’ll need a flat-head screwdriver to remove it.
  • Clean rag: You’ll use this to wipe down the spool housing and remove grass, dirt, and debris before installing the new spool.
  • Small brush (optional): A small paintbrush or old toothbrush works well for cleaning out hard-to-reach debris from the spool housing and line feed mechanism.

All of these items are inexpensive and available at any hardware store, home improvement center, or online retailer. Once you have your materials gathered, you’re ready to start the respooling process.

Step-by-Step Guide to Respool Your Worx Weed Eater

Now that you have your tools and materials ready, follow these simple steps to respool your Worx weed eater quickly and correctly. The entire process takes 10–15 minutes for most users, even if it’s your first time doing it.

Step 1: Prepare Your Weed Eater for Disassembly

Safety is the first priority when working with any power tool, so start by disconnecting the power source. If you have a corded Worx model, unplug it from the electrical outlet. If you have a cordless model, remove the battery pack from the base of the handle. This will prevent accidental startup while you’re working on the spool.

Next, lay the weed eater on a flat, clean surface, like a workbench or garage floor, with the cutting head facing up. If your model has a plastic guard covering the spool housing, remove it first by twisting or sliding it off, depending on your model’s design. Take a moment to wipe away any excess grass, dirt, or debris from the cutting head and spool area with your rag – this prevents dirt from getting inside the housing and causing jams later on.

Step 2: Remove the Old Spool

Most Worx models have a spool housing cap that twists counterclockwise to release. Grip the cap firmly with your hand and twist it until it comes loose – you may need to use a small amount of force if it’s been tightened over time. If your model has a small screw holding the cap in place, use your flat-head screwdriver to remove the screw first, then twist the cap off.

Once the cap is removed, you can pull the old spool straight out of the housing. Some models have a small locking tab on the side of the housing that you need to press down before pulling the spool out, so check your user manual if the spool doesn’t come out easily. Don’t pull too hard, as you don’t want to damage the internal line feed mechanism. Once the old spool is removed, set it aside for disposal or recycling.

Step 3: Clean the Spool Housing and Components

Before installing the new line, take a few minutes to clean out the spool housing to ensure smooth line feed and avoid jams. Use your small brush or rag to remove any built-up grass clippings, dirt, or old line fragments from the inside of the housing. Check the line feed mechanism (the small plastic piece that grabs the line to feed it out) to make sure it’s not clogged or broken. If it’s dirty, wipe it down with a damp rag, but avoid using harsh chemicals, solvents, or abrasive cleaners that could damage the plastic components.

Cleaning the housing is a quick step that will save you a lot of frustration later. Dirt and debris inside the housing are one of the most common causes of line jams, so taking a few minutes to clean it now will ensure your new line feeds smoothly from the start.

Step 4: Wind the New Trimmer Line Correctly

This is the most critical step in the respooling process, and doing it correctly will prevent jams and ensure smooth line feed. Start by taking your replacement trimmer line and cutting it to the length recommended for your model – most Worx spools hold between 10 and 20 feet of line, depending on the diameter. Check your user manual for the exact recommended length, or measure the length of the old line you removed from the spool to get an exact match.

Next, find the center of the line piece and insert one end into the small hole in the center of the new spool. Hold the end in place with your finger to keep it from slipping out, then start winding the line around the spool in the direction indicated by the arrow printed on the spool (almost all Worx spools have a clear directional arrow to show which way to wind). Wind the line tightly and evenly, pressing down slightly as you go to keep the layers compact and prevent overlapping. Loose, overlapping layers will catch on each other and cause jams, so take your time with this step.

If you have a dual-line spool, you’ll need to repeat this process for the second side of the spool, winding the second piece of line in the opposite direction, following the arrow on that side of the spool. Once you’ve wound all the line onto the spool, leave about 6 inches of line hanging out the end, then tuck that end into the small notch on the edge of the spool to hold it in place while you install the spool into the housing.

Step 5: Install the New Spool and Reassemble

Now that your new spool is wound correctly, it’s time to install it. Align the spool with the slot in the spool housing, making sure the line end is sticking out through the line feed slot on the side of the housing. Push the spool firmly into the housing until it clicks into place – most Worx models have a small tab that locks the spool in, so make sure you feel it click to confirm it’s seated properly.

Next, line up the cap with the threads on the housing and twist it clockwise until it’s snug. Don’t overtighten the cap, as this can crack the plastic or warp the spool housing, making it difficult to remove the spool next time you need to respool. If your model uses a screw to hold the cap in place, insert and tighten the screw now, but again, don’t overtighten it.

If you removed a plastic guard earlier, slide or twist it back into place over the spool housing now. Finally, reattach the battery pack (for cordless models) or plug the weed eater back into the electrical outlet. Test the line feed by pressing the line feed button a few times (or tapping the cutting head on the ground, depending on your model) – you should see the line extend smoothly. If it doesn’t feed, double-check that the spool is installed correctly and the line is wound in the right direction.

How to Choose the Right Trimmer Line for Your Worx Weed Eater

Using the wrong type of trimmer line is one of the most common causes of jams, poor cutting performance, and damage to your Worx weed eater. Choosing the right line for your model and use case will ensure smooth operation and extend the life of your spool and tool. There are two main factors to consider when selecting trimmer line: diameter (thickness) and shape.

Line Diameter and Thickness Guide

The diameter of your trimmer line determines how durable it is and how much cutting power it provides. Worx recommends specific line diameters for each of its models, so always check your user manual first before buying line. Here are the most common line diameters and their recommended uses:

  • 0.065 inch: This is the standard line diameter for most residential Worx weed eaters, including the WG150 and WG160. It’s lightweight, easy to feed, and perfect for cutting thin grass, weeds, and light vegetation around sidewalks, driveways, and flower beds.
  • 0.080 inch: This thicker line is designed for mid-range and heavy-duty Worx models, like the WG170 and WG180. It’s more durable than 0.065″ line and can cut through thicker weeds, small brush, and overgrown vegetation without breaking. It’s a good choice for users with larger yards or more demanding trimming needs.
  • 0.095 inch: This is the thickest line diameter available for Worx models, and it’s only recommended for heavy-duty commercial-grade Worx weed eaters. It can cut through thick brush, saplings, and tough vegetation, but it puts more strain on the motor, so only use it if your model is specifically rated for 0.095″ line.

Never use line that’s thicker than the recommended diameter for your model, as this can overheat the motor, damage the line feed mechanism, and void your warranty.

Trimmer Line Shape Options

In addition to diameter, trimmer line comes in several different shapes, each designed for specific cutting tasks:

  • Round line: This is the most common, standard shape of trimmer line. It’s quiet, durable, and works well for general grass and weed trimming. It’s the default line included with most Worx weed eaters.
  • Square line: Square line has sharp, flat edges that cut through thicker vegetation more efficiently than round line. It’s a good choice for users who need to cut through dense weeds or small brush, but it’s louder than round line and wears out slightly faster.
  • Serrated line: Serrated line has small, teeth-like notches along its length that saw through tough, overgrown vegetation with minimal effort. It’s ideal for clearing thick weeds, brush, and even small saplings, but the serrations wear out faster than smooth line, so you’ll need to replace it more often.

Worx recommends using its branded trimmer line for optimal performance, but you can use third-party line as long as it matches the recommended diameter and shape for your model. Avoid cheap, low-quality line that’s prone to breaking and fraying, as this can cause frequent jams and reduce cutting efficiency.

Respooling vs. Replacing the Entire Spool: Cost and Convenience Comparison

When your Worx weed eater runs out of line, you have two options: respool your existing spool with new trimmer line, or buy a pre-wound replacement spool from Worx or a third-party retailer. Both options have pros and cons, so we’ve broken down the key differences in the table below to help you decide which is right for you.

Factor Respooling Your Existing Spool Buying a Pre-Wound Replacement Spool
Average Cost $3–$8 for a 50ft roll of trimmer line (enough for 5+ respools) $10–$20 per pre-wound Worx replacement spool
Time Required 10–15 minutes per respool 5 minutes to swap out the old spool
Waste Generated Minimal – only the old, worn line is discarded Full plastic spool is discarded each time
Performance Identical to original if wound correctly Guaranteed to match factory specifications
Availability Trimmer line is available at all hardware stores, gas stations, and online retailers Worx replacement spools may only be available at specialty outdoor power equipment retailers or online

For most users, respooling is the better choice. It’s far more cost-effective over time, generates less waste, and trimmer line is much easier to find than Worx-specific replacement spools, especially if you live in a rural area with limited retail options.

Common Mistakes to Avoid When Respooling a Worx Weed Eater

Even though respooling is a simple process, there are a few common mistakes that can lead to jams, poor line feed, and even damage to your tool. Avoid these pitfalls to make the process as smooth as possible:

  1. Winding the line in the wrong direction: This is the most common mistake, and it will cause the line to not feed properly or jam inside the housing. Always follow the directional arrow on the spool when winding.
  2. Winding the line too loosely: Loose, overlapping layers will catch on each other and cause jams. Wind the line tightly and evenly, pressing down slightly to keep it compact.
  3. Using the wrong line diameter: Line that’s too thick will strain the motor and won’t fit through feed slots, while line that’s too thin breaks easily. Check your manual for the recommended diameter.
  4. Overfilling the spool: Overfilling causes overlapping and jams. Fill only to the line marked on the spool, or leave a small gap between the line and the spool edge.
  5. Forgetting to tuck the line end: If you don’t secure the line end in the spool notch, it will fall into the housing and cause a jam. Always tuck the end in before installing the spool.
  6. Overtightening the spool cap: This can crack the plastic cap or warp the housing, making the spool hard to remove next time. Tighten until snug, no extra force needed.

If you make one of these mistakes, don’t worry – most issues are easy to fix. Simply remove the spool, unwind the line, and rewind it correctly following the steps in this guide.

Pro Tips for Longer Spool Life and Better Performance

Once you’ve mastered the basics of respooling, these pro tips will help you extend the life of your spool and get the best performance from your Worx weed eater:

  • Store extra trimmer line in a cool, dry place out of direct sunlight. UV exposure makes line brittle, so shaded storage extends its shelf life by months.
  • Avoid trimming near concrete, rocks, or other hard surfaces. These nick and fray line much faster than grass, so keep the cutting head a few inches away.
  • If line wears unevenly, check the line feed mechanism for burrs or debris. A quick wipe with a damp rag often fixes feeding issues.
  • For cordless models, use 0.065″ line to reduce battery strain and extend runtime. Thicker line uses more power per charge.
  • Leave small gaps between line layers when winding to prevent binding in hot weather. Line expands in high temps, so slack avoids jams.
  • For thick vegetation, use serrated or square line for better cutting efficiency. These shapes cut tough plants with less effort, reducing line and motor wear.

Following these simple tips will help you get the most out of your trimmer line and reduce how often you need to respool your Worx weed eater.

Frequently Asked Questions

How often should I respool my Worx weed eater?

Respooling frequency depends on use and vegetation type. For light weekly residential use, respool every 1–2 months. For heavy use clearing thick weeds or brush, respool every 2–4 weeks. Inspect line before each use for wear or fraying, and respool as needed to avoid tool damage.

Can I use third-party trimmer line on my Worx weed eater?

Yes, as long as the third-party line matches the recommended diameter and shape for your model. Worx does not require branded line for warranty coverage, so any high-quality compatible line works. Avoid cheap, low-quality line that breaks easily and causes jams.

Why does my trimmer line keep jamming after respooling?

Jams are almost always caused by three issues: line wound in the wrong direction, loose/overlapping winding, or an overfilled spool. Double-check winding direction, tightness, and fill level. If jams persist, clean the line feed mechanism of debris or damage.

How much trimmer line do I need for a Worx weed eater spool?

Most Worx spools hold 10–20 feet of line, depending on model and diameter. Thinner 0.065″ line fits more length than thicker 0.080″ or 0.095″ line. Check your user manual for exact requirements, or measure the old line you removed for a perfect match.

Can I respool my Worx weed eater without any tools?

Most modern Worx models are tool-free for respooling, as the spool cap twists off by hand. Some older or heavy-duty models have a screw holding the cap in place, requiring a flat-head screwdriver. Check your user manual if you’re unsure.
