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
- Pre-wound replacement trimmer spool
- Direct-fit for listed trimmer models

Compatibility
This spool is designed for Toro 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 the 88616 / 144-4108 dual line spool fit my Toro 60V Flex Force trimmer model 51834T?
Yes, this replacement spool is made for Toro 60V Max Flex Force string trimmers including models 51831, 51831T, 51881, 51834, and 51834T. If your trimmer matches one of those model numbers and uses the 13/15 or 14/16 inch cutting setup, this spool is the correct fit.
Q: Do I need to hand-wind line onto this 88616 144-4108 spool before installing it?
No, this is a replacement dual line spool, so it comes ready to install without rewinding line by hand. Just remove the old spool, clean out any packed grass or debris in the spool head, and seat the new spool correctly so the line feeds smoothly.
Q: My line keeps sticking or not feeding evenly on my Toro 51881—will replacing the spool help?
If the line is worn, fused together, or the spool is damaged, replacing it with a fresh 88616 / 144-4108 spool often fixes uneven feeding. It also helps to check that the spool cap and housing are clean and undamaged, because buildup inside the head can cause feeding problems even with a new spool.
