Overview

Keep your string trimmer ready for action with this pre-wound replacement spool. It is built to the same dimensions as the OEM spool, so it drops right into the trimmer head with no modifications. Aftermarket spools provide the same cutting performance as factory originals at a better value.

Key specifications

  • Pre-wound replacement trimmer spool
  • Line diameter: 0.080”
  • 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

Remove the spool cover from the trimmer head. Extract the old spool and clean out any grass or debris. Insert the new pre-wound spool, feed the line ends through the guide holes, and reattach the cover. Verify the line extends the correct length before trimming.

Common questions

Q: Will this 0.080-in x 30-ft spooled trimmer line fit the Toro 51831 and 51881 60V 13” & 15” brushless string trimmers?

Yes, this spool is made for the Toro 51831, 51831T, and 51881 60V 13-inch and 15-inch electric brushless string trimmers using the 51831 trimmer head replacement setup. If your trimmer matches those model numbers, this line size and spool configuration are the correct fit.

Q: Do I need to wind this 30-ft trimmer line myself, or does it come ready to install in the trimmer head?

This is a spooled trimmer line, so it is already wound and intended to be installed directly into the compatible trimmer head. Just remove the old spool, check the head for debris or worn eyelets, and seat the new spool with the line routed correctly to prevent feeding issues.

Q: Is 0.080-inch line a good choice for regular yard trimming on the Toro 60V trimmers, and how can I make it last longer?

Yes, 0.080-inch line is the correct size for these Toro models and works well for normal grass trimming and light weeds without overloading the head. For longer life, avoid striking concrete and fencing, and keep the spool area clean so the line can feed smoothly instead of binding or breaking early.

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.
