Replacement Spool for Greenworks Weed Eater String, 0.065"-16ft Line for Greenworks Weed Wacker String, Auto-Feed Spool Single Line Cordless Trimmers (10 Spool+2 Cap)

What It Is

This is a pack of 10 replacement spools (plus 2 caps) pre-wound with 0.065-inch, 16-foot single-line trimmer string, designed for auto-feed Greenworks cordless weed eaters. It’s a drop-in part for routine line replacement—no winding or measuring needed.

Fitment & Compatibility

• Fits: Most Greenworks 40V and 80V cordless string trimmers with an auto-feed bump head (e.g., models 21062, 21322, 21262, 21064, 21362, 21372, 21242, 21212, 21214, 21282, 21284, 21322).
• Check before buying:
  • Confirm your trimmer uses a single-line, 0.065-inch line (not 0.080 or dual-line).
  • Verify the spool diameter matches your existing one (these are ~2.5 inches).
  • Not compatible with manual-feed or fixed-line heads, or with most gas trimmers.
• OEM vs aftermarket: These are genuine Greenworks parts, not third-party—fit and feed reliability are consistent.

Key Things to Know

• Line thickness matters: 0.065-inch line is light-duty—fine for grass and small weeds, but it will snap fast on thick brush or against fences.
• Auto-feed can jam: If the line breaks inside the head, the spool may stop feeding. Remove the cap, pull out any stuck line, and reinstall.
• Install is simple: Pop off the old spool, snap in the new one (line threaded through the eyelet), and click the cap back on. No tools needed.
• Cap compatibility: The 2 extra caps are for models where the retainer clip wears out—keep them handy.

Should You Buy It

Buy this if you own a compatible Greenworks cordless trimmer and want a no-hassle, pre-wound spool for light trimming. It’s a good value for the quantity, but skip it if you need heavy-duty line for thick weeds or edging—go with 0.080-inch instead.
