What It Is

This is a pre-wound bump spool head replacement for Greenworks front-mount string trimmers, loaded with dual 0.080-inch, 17-foot lines. It’s designed for homeowners needing a quick drop-in fix for trimming grass and weeds.

Fitment & Compatibility

Check that your trimmer is a Greenworks front-mount model—this spool fits STG401, ST60V, ST60V-T0, ST60L210, ST60L00, ST60B00, ST80L200, and other 60V/80V front-mount units. Measure your existing spool housing: this head is about 3.5 inches wide and uses a standard spring-loaded bump feed. It’s not compatible with rear-mount or curved-shaft trimmers. Confirm your model’s bump head type (this is a direct replacement, not a universal adapter). If your trimmer uses a different feed mechanism (e.g., fixed-line or auto-feed), this won’t work.

Key Things to Know

• Pre-wound convenience: Comes with line installed, so no winding—just snap it on. But .080-inch line is thinner than some OEM stock (often .095-inch), so it cuts fine grass well but may snap on thick weeds or briars.
• Installation ease: Most users install in under 5 minutes—no tools needed. Just align the tabs and press. If your old head is stuck, use pliers carefully to avoid stripping the plastic.
• Durability concerns: Some reviews report the plastic housing cracks after a few uses on rocky terrain. It’s best for light-to-moderate trimming on maintained lawns.
• Bump feed reliability: The bump mechanism can jam if line is too long or if debris gets inside. Trim line ends to 6-7 inches after each refill.

Should You Buy It

If you own a compatible Greenworks front-mount trimmer and want a hassle-free, pre-wound replacement for light residential use, this spool is a decent budget option. But if you tackle heavy weeds or rocky edges, consider a heavier-duty aftermarket head with thicker line (e.g., .095-inch) for better durability.
