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
  • Direct-fit for listed trimmer models
  • Bump-feed compatible winding pattern

Compatibility

This spool is designed for Scotts 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 replacement spool fit both the Scotts ST00213S 13” corded string trimmer and the Earthwise ST00011, ST00013, and ST00015 models?

Yes, this spool is made for the Scotts ST00213S 13” corded trimmer and is also compatible with the Earthwise ST00011, ST00013, and ST00015 string trimmers. If your trimmer matches one of those exact model numbers, the spool should fit and feed correctly.

Q: How do I install this replacement spool on my Scotts ST00213S trimmer?

First, unplug the corded trimmer before doing any service. Remove the spool cap, take out the old spool, clean out any grass or debris in the spool housing, then set the new spool in place and feed the line through the eyelets before snapping the cap back on securely.

Q: Is there anything I should do to help the replacement string spool last longer on my Earthwise ST00015?

Yes, try to avoid hitting concrete, chain-link fencing, and heavy weeds for long periods, since that wears the line down much faster. It also helps to periodically clear debris from the spool head and check that the line is feeding smoothly so the spool does not bind or wear unevenly.

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.
