Overview

Engineered for durability, this aftermarket trimmer line provides consistent cutting performance for residential and light commercial trimming. Line diameter directly affects cutting ability: thicker line handles heavier vegetation, while thinner line works best for fine grass trimming. This replacement line matches the OEM specification for your trimmer.

Key specifications

  • Replacement trimmer line
  • Commercial-grade nylon construction
  • Resistant to fraying and breakage
  • Compatible with bump-feed and fixed-line trimmer heads

Compatibility

This line is compatible with Greenworks trimmers as listed above. Verify the line diameter matches your trimmer’s specification to ensure proper fit in the spool housing and guide eyelets.

Installation notes

Turn off the trimmer, remove the spool housing cover, and extract the spool. Cut the new line to the length specified on the spool or in the trimmer manual. Wind evenly in the direction indicated by the arrow on the spool, reinstall, and test the bump-feed advance.

Common questions

Q: Will this 2906302 SB00L00 replacement trimmer line fit my Greenworks ST80L00 and Toro 51881, or is it only for one brand?

Yes, this line is made to fit the Greenworks STF402 spool used on models ST80L210, ST80L00, and STBA80L210, and it also matches Toro 60V models 51881, 51831, and 51831T. The key spec is the 0.080-inch line size, so if your trimmer uses that size and these model numbers, it should install correctly.

Q: Do I need to wind this trimmer line myself, or does it drop into the spool assembly ready to use?

That depends on whether you’re replacing just the line or refreshing the spool setup, but this 2906302 SB00L00 is the correct 0.080 line type for the listed Greenworks and Toro models. When installing, make sure the line is seated evenly and routed through the eyelets properly so it feeds smoothly without tangling.

Q: My trimmer keeps breaking line quickly—will this 0.080 replacement line help, and is there anything I should check?

A fresh 0.080 line can improve cutting performance if your old line has become brittle or worn, especially on ST80L00 or Toro 51831 units. For best results, avoid overfilling the spool, inspect the spool cap for wear, and keep the cutting path clear of heavy contact with concrete, chain-link fence, or rocks since those surfaces shorten line life fast.

Before you buy — how to verify fitment

  1. Find your trimmer model number. It's usually on a label on the motor housing, battery slot, or lower shaft.
  2. Check spool compatibility. Compare the model number with the compatibility list above.
  3. Verify line gauge. Confirm the line thickness matches what your trimmer head requires by checking your manual or the old spool.
  4. Inspect the spool housing. Make sure the spool diameter, cap, spring post, and feed style match your trimmer head.

Frequently asked questions

How do I know this spool fits my trimmer?

Check your trimmer model number against the compatibility list above. Then verify the line gauge (.065, .080, .095) matches what your trimmer head requires — it's usually printed on the spool cap or in the manual.

Can I rewind a pre-wound spool?

Yes. Once the factory line runs out, you can rewind the spool with bulk trimmer line of the same gauge. Pre-wound spools just save time on the first load.

How often should I replace the spool?

Replace the spool when the line no longer feeds properly, the spring loses tension, or the spool body is cracked. Under normal weekend use, a spool lasts 2–4 refills before the housing wears out.

What gauge trimmer line should I use?

Match the gauge to your trimmer's power: .065" for light-duty electric trimmers, .080" for mid-range cordless, and .095" for gas-powered or heavy-duty models. Using too thick a line can stall the motor.
