Ryobi String Trimmer Head Will Not Feed: How to Fix It

Q: Why does my Ryobi trimmer line keep breaking?

Line breaks due to using the wrong diameter, old brittle line, hitting hard objects like concrete, or running the trimmer at too high RPM. Use fresh line with the correct diameter specified in your manual and avoid contact with hard surfaces.

Q: What size trimmer line should I use in my Ryobi string trimmer?

Most Ryobi string trimmers use 0.065-inch or 0.080-inch diameter line. Check your owner's manual or the label on the trimmer head for the exact specification, as using the wrong size can cause feeding problems.

Q: How much line should I put on the spool?

Typically 10 feet of line total, wound evenly with about 6 inches extending from each side when finished. Overfilling the spool can cause tangling and prevent proper feeding.

Q: Can I use any brand of trimmer line in my Ryobi trimmer?

Yes, any quality trimmer line with the correct diameter will work. Round line works best for general use, while square or serrated line cuts better but may cause more wear on the trimmer head.

Q: How often should I replace the trimmer line?

Replace line when it becomes worn, brittle, or breaks frequently. With normal use, you may need to rewind fresh line every few trimming sessions, or whenever the automatic feed stops working properly.

Abstract

When your Ryobi string trimmer head won't feed line, it's usually caused by tangled, worn, or incorrectly wound trimmer line. This bump-feed jam prevents new line from advancing when you tap the head on the ground during operation.
