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.

Key specifications

  • Pre-wound replacement trimmer spool
  • Line diameter: 0.065”
  • Line length per spool: 30 ft
  • Direct-fit for listed trimmer models
  • Bump-feed compatible winding pattern

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

Power off the trimmer and press the tabs on the spool housing to release the cover. Pull out the empty spool and clear any debris from the housing interior. Drop in the new spool, route the line through the eyelets, and snap the cover back on.

Common questions

Q: Will this 88518/88528 spool with cap fit my Toro 51488T and my older Toro 51480 trimmer?

Yes, this replacement spool with cap is made to fit Toro 51488, 51488T, and 51480 models. It’s also matched for units that use a 0.065” dual-line, 30 ft spool, so if your trimmer matches those specs, it should install correctly.

Q: Is this spool compatible with Greenworks models STBA40B210, BST4000, and 2101602A, or is it only for Toro trimmers?

It is compatible with listed Greenworks 40V string trimmers including STBA40B210, BST4000, 2101602, 2101602A, and ST40B410. The key thing to verify is that your trimmer uses a 0.065” dual-line spool in the 30 ft size, since that’s the configuration this replacement is designed around.

Q: Do I need to wind line onto this spool myself, and are there any installation tips for the cap?

This style of replacement spool is typically ready to install, so you shouldn’t need to rewind line before use. When installing, clean out any grass or debris from the spool housing first, then seat the spool evenly and make sure the cap snaps on securely so the line feeds smoothly during trimming.

Before you buy — how to verify fitment

  1. Find your trimmer model number. It's usually on a label on the motor housing, battery slot, or lower shaft.
  2. Check spool compatibility. Compare the model number with the compatibility list above.
  3. Verify line gauge. Confirm the line thickness matches what your trimmer head requires by checking your manual or the old spool.
  4. Inspect the spool housing. Make sure the spool diameter, cap, spring post, and feed style match your trimmer head.

Frequently asked questions

How do I know this spool fits my trimmer?

Check your trimmer model number against the compatibility list above. Then verify the line gauge (.065, .080, .095) matches what your trimmer head requires — it's usually printed on the spool cap or in the manual.

Can I rewind a pre-wound spool?

Yes. Once the factory line runs out, you can rewind the spool with bulk trimmer line of the same gauge. Pre-wound spools just save time on the first load.

How often should I replace the spool?

Replace the spool when the line no longer feeds properly, the spring loses tension, or the spool body is cracked. Under normal weekend use, a spool lasts 2–4 refills before the housing wears out.

What gauge trimmer line should I use?

Match the gauge to your trimmer's power: .065" for light-duty electric trimmers, .080" for mid-range cordless, and .095" for gas-powered or heavy-duty models. Using too thick a line can stall the motor.
