Overview
This pre-wound replacement spool drops directly into compatible string trimmers, eliminating the hassle of hand-winding line. Worn or empty spools leave trimmer owners without a cutting edge mid-job. Keeping spare aftermarket spools on hand ensures minimal downtime and consistent line feed during yard work.

Common questions
Q: Will this 6-piece spool set fit my Hyper Tough K1018 20V string trimmer, and do the HT21-401-003-02 / HT21-401-003-03 numbers need to match exactly?
Yes, this set is made for the Hyper Tough K1018 20V String Trimmer and also fits LawnMaster 20VMWGT and CLGT2410H models. Those replacement numbers are compatible part references for this spool set, so the important thing is matching your trimmer model first rather than needing every printed number on the old spool to be identical.
Q: How do I install these replacement spools on a LawnMaster CLGT2410H without the line tangling or feeding incorrectly?
Remove the battery first, then open the trimmer head and take out the old spool and cap. Drop the new spool in with the line routed through the eyelets, make sure it spins freely in the correct direction, and leave a short length of line extended before snapping the cap back on to help it feed properly.
Q: Are these HT19-401-003-06 / HT22-401-03-05 replacement spools pre-wound, and is there anything I should do to make them last longer?
Yes, these are pre-wound replacement spools, so you can install them directly without manually winding new line. For longer life, avoid hitting concrete, chain-link fencing, and thick woody stems, and clean grass debris from the spool housing regularly so the auto-feed system doesn’t bind up.
