Overview
This aftermarket replacement spool comes pre-loaded with trimmer line at the correct diameter and winding pattern for your trimmer. When the original spool runs empty or the line becomes brittle from UV exposure, swapping in a fresh spool is faster than re-winding. The pre-wound design ensures consistent bump-feed performance from the start.
Key specifications

Compatibility
This spool is designed for Husqvarna string trimmers as listed above. Confirm the spool part number, line diameter, and trimmer model before ordering to ensure a proper fit.
Installation notes
Turn off the trimmer and remove the spool cover by pressing in the retaining tabs. Remove the old spool and wipe out the housing. Insert the replacement spool, thread the line ends through the eyelets, and snap the cover into place. Test the bump-feed mechanism by tapping the head and pulling the line.
Common questions
Q: Will this 6PC T25 replacement spool fit my Husqvarna 128LD and 122C trimmer, or is it only for the T25 head 966674401?
Yes, these spools are made for the Husqvarna T25 trimmer head and are compatible with models that use that head, including the 128LD and 122C. It also fits other listed models like 122L, 128LX, 128R, 130C, 223L, and 115iL, as long as your trimmer is using the T25 head that takes spool 537338601.
Q: Are these replacement spools pre-wound with .095 line, and do I need to rewind them before installing?
These are replacement real spools for the T25 setup that uses .095 trimmer line, so they are intended to match the Husqvarna 537338601 spool specification. Installation is usually just opening the T25 head, removing the old spool, and dropping the new one in with the line ends routed correctly through the eyelets.
Q: My T25 head keeps tangling or not feeding line correctly on my Husqvarna 115iL—will replacing the spool help, and is there anything I should check during installation?
A worn or damaged spool can definitely cause poor line feeding, binding, or uneven bump feed, so replacing it often solves that issue. While installing, make sure the spring and cap are seated properly, the line exits cleanly through both eyelets, and there is no debris packed inside the head, since dirt and grass buildup can also cause feeding problems.
