Understanding Your Weed Eater Head
Before you can rewind line, you must know which head you are dealing with. The three most common designs are bump feed, fixed line, and dual line. Each has a distinct spool geometry and feeding mechanism, which influences the rewind technique.
Types of Heads
Bump feed heads release line when you tap the head on the ground. They contain a spring‑loaded spool that advances line automatically. Fixed line heads hold a pre‑cut length of line that does not advance; you replace the entire spool when the line wears out. Dual line heads run two parallel strands, providing a wider cutting swath and often use a bump feed mechanism for each strand.
Line Specifications
Line diameter typically ranges from 0.065 in to 0.155 in. Thicker line cuts tougher vegetation but demands more power. Always consult the owner’s manual for the recommended diameter and maximum length. Using the wrong size can cause jams, excessive vibration, or premature wear.
Tools and Materials Needed
- Replacement trimmer line (correct diameter and length)
- Scissors or a sharp utility knife
- Gloves (cut‑resistant preferred)
- Safety glasses
- Clean rag or brush for debris removal
- Owner’s manual for reference
Safety Precautions
Always disconnect the spark plug wire (gas models) or remove the battery (cordless models) before servicing the head. Wear eye protection to guard against snapped line fragments. Keep hands clear of the cutting area while the engine is running. Work on a stable, flat surface to prevent the trimmer from tipping.
Step-by-Step Guide: How to Rewind Weed Eater Line?
The following universal steps apply to most bump feed heads. Adjustments for fixed or dual line heads are covered in the subsequent sections.
- Remove the head. Unscrew the retaining knob or press the release tabs, then pull the head assembly off the drive shaft.
- Open the spool. Separate the two halves of the spool by pressing the locking tabs or unscrewing the center cap.
- Clear old line. Pull out any remaining line fragments and clean debris from the spool cavity.
- Measure new line. Cut a length of line according to the manual (usually 10–25 ft). For dual line heads, cut two equal lengths.
- Insert the line. Feed one end of the line through the eyelet on the spool, then wind it neatly in the direction indicated by the arrow on the spool.
- Maintain tension. Keep the line taut while winding to prevent overlapping or loose loops.
- Leave a tail. Leave about 6 in of line protruding from the eyelet for the feed mechanism.
- Reassemble the spool. Snap the halves together, ensuring the line tails sit in the notches.
- Reattach the head. Mount the head back onto the drive shaft and secure the retaining knob or tabs.
- Test the feed. Reconnect power, start the trimmer, and tap the head on the ground to verify smooth line advance.
Rewinding a Bump Feed Head
Bump feed heads are the most common on residential trimmers. The key is to wind the line in the direction of the arrow—usually clockwise when viewing the spool from the top. After winding, the line must sit in the designated notches so the bump mechanism can grab it. If the head has a spring, compress it gently while re‑assembling to avoid damaging the spring.

Rewinding a Fixed Line Head
Fixed line heads do not advance line automatically. Instead, you replace the entire spool or reload a pre‑cut length. Open the head, discard the old spool, and insert a new pre‑wound spool that matches the manufacturer’s part number. Some models allow you to wind your own line onto a reusable spool; follow the same winding direction rules as for bump feed heads.
Rewinding a Dual Line Head
Dual line heads require two equal lengths of line. Feed each strand through its own eyelet, then wind both simultaneously, keeping them side by side. Many dual heads have a divider ridge on the spool to keep the strands separated. After winding, each tail must sit in its own notch. Test by bumping the head; both lines should extend evenly.
Comparison Table: Head Types vs. Rewinding Method
| Head Type | Line Advance | Rewind Complexity | Typical Line Diameter | Best Use Case |
|---|---|---|---|---|
| Bump Feed | Tap to advance | Moderate – wind manually | 0.080–0.105 in | General residential trimming |
| Fixed Line | No advance – replace spool | Low – swap pre‑wound spool | 0.065–0.095 in | Light duty, occasional use |
| Dual Line | Tap to advance (both strands) | Higher – wind two strands | 0.095–0.130 in | Large areas, thick weeds |
Tips and Best Practices
- Wind line tightly and evenly; loose loops cause feeding problems.
- Use the exact line diameter specified by the manufacturer.
- Store spare line in a cool, dry place to prevent brittleness.
- Clean the spool cavity each time you rewind to remove grass buildup.
- If the head has a wear indicator, replace the spool when the line reaches that mark.
- Periodically lubricate the bump mechanism with a light silicone spray.
Common Mistakes and How to Avoid Them
One frequent error is winding the line opposite the arrow direction, which prevents the bump feed from engaging. Another is over‑filling the spool; excess line can jam the head and stall the engine. Using a line diameter that is too thick for the motor leads to overheating and reduced cutting speed. Forgetting to leave a sufficient tail length results in the line not catching on the feed mechanism. Finally, neglecting to clean debris from the spool cavity causes premature wear and uneven feeding.
Troubleshooting Line Feeding Issues
If the line does not advance when you bump the head, first verify that the line is wound in the correct direction and that the tails are seated in the notches. Check for a broken or weakened spring inside the bump mechanism. Inspect the eyelets for burrs or cracks that could snag the line. Ensure the spool halves are fully snapped together; a loose fit allows the line to slip. If the engine runs but the head does not spin, confirm that the drive shaft is securely connected and that the clutch is not worn.
Frequently Asked Questions
How often should I rewind the line?
Rewind whenever the line length drops below the minimum effective cutting length, typically when only 2–3 in remain. Heavy use may require rewinding every few hours; light use can go weeks between rewinds. (See Also:How To Get A Weed Eater To Start)
Can I use any brand of trimmer line?
While many brands are compatible, always match the diameter and shape (round, square, twisted) recommended by the trimmer manufacturer. Incompatible line can cause feeding problems or damage the head.
Why does my line keep breaking near the eyelet?
Sharp edges on the eyelet, excessive tension while winding, or using line that is too thin for the workload can cause breakage. Inspect the eyelet for burrs and smooth them with fine sandpaper if needed.
The bump feed isn’t advancing line. What should I do?
Check that the line is wound correctly, the tails are in the notches, and the spring is intact. Clean any grass buildup inside the head. If the problem persists, the bump mechanism may need replacement.
My dual line head feeds unevenly. How can I fix it?
Ensure both strands are cut to the exact same length and wound side by side without crossing. Verify that each tail sits in its own notch. Uneven wear can also indicate a worn divider ridge on the spool. (See Also:What Oil Does Weed Eater Take)
Conclusion
