Understanding Your Ryobi Weed Eater
Ryobi offers a wide range of string trimmers, from lightweight 18‑volt cordless models to robust 40‑volt brushless units. Despite the differences in power source, the cutting head mechanism is remarkably consistent across the lineup. Most current Ryobi trimmers use a removable head that snaps onto the drive shaft, allowing you to swap heads or replace the line without tools. Knowing whether your model uses a bump‑feed, fixed‑line, or dual‑line head is the first step toward a successful restring.
Check the model number on the motor housing or the owner’s manual. The manual will list the compatible head type and the recommended line diameter, usually 0.080 in or 0.095 in for residential models. If you have lost the manual, Ryobi’s website provides downloadable PDFs for every model, and the head type is often printed on a label near the head mounting point.
Types of String Trimmer Heads
There are three common head designs you will encounter on Ryobi trimmers:
- Bump‑feed (or “tap‑feed”) head – The most popular design. You tap the head on the ground while the motor runs, and a spring‑loaded mechanism advances fresh line.
- Fixed‑line head – Holds a pre‑cut length of line that does not advance automatically. You must manually pull out new line when the existing piece wears down.
- Dual‑line head – Similar to a bump‑feed but feeds two lines simultaneously, giving a wider cutting swath and faster grass removal.
Each head has a slightly different loading procedure, but the core principle—feeding line through the eyelets and winding it onto the spool—remains the same. The next sections break down the specifics for each type.
Choosing the Right Line
Line diameter, shape, and material all affect cutting performance and line life. Ryobi typically recommends 0.080 in (2.0 mm) round line for light‑duty work and 0.095 in (2.4 mm) for thicker weeds. Here are the main options:
- Round nylon – General purpose, affordable, good for grass and light weeds.
- Twisted or serrated line – Cuts cleaner through tough stems, reduces fraying.
- Square or star‑shaped line – Provides a sharper cutting edge, ideal for heavy brush.
- Co‑polymer or reinforced line – Higher abrasion resistance, lasts longer on rocky terrain.
Always match the line diameter to the head’s specifications. Using a line that is too thick can jam the feed mechanism; too thin and it will break prematurely. Purchase line in bulk spools (typically 1‑lb or 5‑lb) to keep the cost per foot low.
Tools You’ll Need
Restringing a Ryobi trimmer is a tool‑light job. Gather the following before you start:
- Replacement line (correct diameter and length)
- Scissors or a sharp utility knife
- Gloves (optional, but they protect hands from sharp line ends)
- Safety glasses (recommended when cutting line)
- Clean rag (to wipe debris from the head)
No wrenches or screwdrivers are required for most Ryobi heads because they use a tool‑less latch. If your model has a bolt‑on head, a 10 mm socket or adjustable wrench will be needed.
Step‑by‑Step: How Do You String a Ryobi Weed Eater?
The following generic procedure applies to most Ryobi bump‑feed heads. Later sections detail the nuances for fixed‑line and dual‑line heads.
- Power off and disconnect – Remove the battery (cordless) or unplug the unit (corded). Ensure the motor cannot start accidentally.
- Remove the head – Press the release tabs on the side of the head and pull it straight off the drive shaft. Set the head on a clean work surface.
- Open the spool – Most bump‑feed heads have a two‑piece spool that snaps apart. Separate the halves by pulling the retaining tabs.
- Cut the line – Measure a length of line roughly 10–12 ft (3–3.5 m) for a single‑line head, or 20–24 ft for a dual‑line head. Cut cleanly with scissors.
- Insert the line – Find the anchor hole or slot on the spool. Feed one end of the line through the hole, leaving a short tail (about 2 in) to hold.
- Wind the line – Turn the spool in the direction indicated by the arrow on the head (usually clockwise). Keep tension even; avoid overlapping or crossing the line.
- Secure the line – When the spool is full, tuck the free end into the notch or slot provided. Snap the spool halves back together.
- Reattach the head – Align the head with the drive shaft and push until the release tabs click into place.
- Test the feed – Reinstall the battery, start the trimmer, and gently tap the head on the ground. The line should advance smoothly.
Loading a Bump Feed Head
Bump‑feed heads are the most common on Ryobi trimmers. The key to reliable feeding is winding the line tightly and evenly. Follow these extra tips:
- Wind the line in the direction of the arrow; winding backward will cause the line to jam.
- Leave a small gap (about 1/8 in) between the wound line and the spool flange to prevent binding.
- If the head has two separate line channels (dual‑line bump feed), repeat the winding process for each channel, keeping the lengths equal.
After re‑assembly, give the head a few test taps on a soft surface. If the line does not advance, open the spool again and verify that the line is not crossed or caught on the spring.
Loading a Fixed Line Head
Fixed‑line heads are simpler because there is no spring mechanism. The line is held by a set of notches or a clamping tab.
- Remove the head and open the spool as described above.
- Cut a single piece of line to the length recommended in the manual (usually 8–10 ft).
- Thread one end through the anchor hole, then pull the line through the guide eyelet on the head body.
- Pull the line taut and seat the free end into the retaining notch.
- Close the spool, reattach the head, and test. When the line wears down, simply pull a new length through the same path.
Because there is no automatic feed, you will need to stop the trimmer and manually pull more line when the cutting edge becomes dull.
Loading a Dual Line Head
Dual‑line heads double the cutting width by feeding two lines side by side. The loading process is essentially two single‑line loads performed simultaneously.
- Remove the head and separate the spool halves.
- Cut two equal lengths of line (typically 12–14 ft each).
- Insert the first line into the left anchor hole, wind it onto the left side of the spool following the arrow.
- Insert the second line into the right anchor hole, wind it onto the right side, keeping tension identical.
- Secure both ends in their respective notches, snap the spool together, and reinstall the head.
When tapping the head, both lines should advance together. If only one line feeds, check for a crossed line or a blocked eyelet on the non‑feeding side.
Common Mistakes to Avoid
Even experienced users can make errors that lead to frustration or damage. Watch out for these pitfalls:
- Over‑filling the spool – Too much line prevents the bump mechanism from moving freely.
- Winding in the wrong direction – The arrow on the head indicates the correct wind direction; ignoring it causes the line to lock.
- Using the wrong diameter – Thick line in a 0.080 in head will jam; thin line in a 0.095 in head will snap.
- Leaving line tails too long – Long tails can catch on the guard or the motor housing.
- Not cleaning the head before loading – Grass clippings and dirt can impede the feed spring.
Taking a few extra seconds to verify each step saves time later and extends the life of both the line and the head.
Maintenance Tips for Longer Line Life
Proper care of the trimmer head and line reduces the frequency of restringing and improves cutting quality.
- Store line in a cool, dry place – UV exposure and moisture make nylon brittle.
- Trim at the correct RPM – Running the motor at full throttle for light grass wastes line; lower the speed when possible.
- Avoid hard surfaces – Hitting concrete, rocks, or metal edges shreds line instantly.
- Clean the head after each use – Remove grass buildup from the spool and feed spring with a brush or compressed air.
- Inspect the feed spring – A weakened spring will not advance line reliably; replace it if you notice sluggish feeding.
Following these habits can double the usable length of a spool, especially when using reinforced co‑polymer line.

Frequently Asked Questions
How often should I restring my Ryobi weed eater?
Restring whenever the line no longer cuts cleanly or the feed mechanism stops advancing. For average residential use, this is typically every 2–4 hours of cutting time.
Can I use any brand of trimmer line?
Yes, as long as the diameter matches the head’s specification. Ryobi‑branded line is optimized for their heads, but quality third‑party lines work equally well.
Why does my line keep breaking at the eyelet?
Sharp edges on the eyelet or a mis‑aligned spool can cause premature breakage. Inspect the eyelet for burrs and smooth them with a fine file if needed.
Is it necessary to wear gloves while restringing?
Gloves are not mandatory but they protect your hands from sharp line ends and from any residual debris on the head.
What do I do if the bump feed won’t advance line?
First, ensure the line is wound in the correct direction and not over‑filled. Then check the feed spring for damage or debris. Cleaning the spring and re‑winding usually solves the issue.
Can I convert a fixed‑line head to a bump‑feed head?
Most Ryobi models allow head swaps. Purchase a compatible bump‑feed head for your model number and install it using the same tool‑less latch.
