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

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.
