THE RIGHT TOOL FOR THE JOB

Trimmer Line & Spools

Replacement line and spools are small purchases that benefit from exact matching. Read the trimmer's approved diameter, material, and spool requirements, then compare the package. Keep the loading instructions handy so the refill suits both the head and the way it feeds.

Trimmer Line & Spools

Greenworks 2906302 .080-inch trimmer line, 160 feet

This 160-foot supply of .080-inch line is a useful refill to keep beside a Greenworks trimmer that calls for that diameter. Cut and load the amount specified for its head.

Good for Owners refilling an approved .080-inch line head who prefer bulk line to buying a prewound replacement spool.

Keep in mind Bulk line needs measuring and winding into the correct head; the package does not replace a damaged spool or head.

A FEW POINTERS

Choose with your garden in mind.

What matters most

  • Match the exact model and approved line specification.
  • Check spool fit and loading instructions.

Where the tradeoffs land

  • Line thickness alone cannot establish compatibility.
  • Some heads use a specific preloaded spool.
GOOD QUESTIONS

Before you head outside

Can I choose thicker line for tougher weeds?

Use only the line sizes and types approved for the exact trimmer. Check the intended vegetation and head requirements before changing the setup.
