YWTESCH 8 Pcs CMZST0653 Weedeater String Compatible with Craftsman Weed Wacker, 30Ft 0.065" Trimmer Line Fit for Craftsman CMCST900, CMESTA900, CMESTE920, CMZST98020, CMCST915, CMEST913

What It Is

This is a set of 8 pre-cut trimmer line spools (30 feet total, 0.065-inch diameter) designed for Craftsman battery-powered weed wackers. It’s a direct replacement for the CMZST0653 string – just snap in and trim, no winding required.

Fitment & Compatibility

Before buying, confirm your model matches this list: CMCST900, CMESTA900, CMESTE920, CMZST98020, CMCST915, CMEST913. These are all Craftsman 60V or 40V battery trimmers with a bump-feed head that accepts pre-wound spools. Check your unit’s model number (on the trimmer or battery cradle) – if it’s not listed, measure the spool diameter (about 2.5 inches) and ensure your head uses a 0.065-inch line. This is aftermarket, not OEM Craftsman, but fits the same spool housing.

Key Things to Do

• Line thickness is fixed at 0.065-inch – good for light trimming (grass, small weeds). Not for thick brush or heavy-duty cutting.
• Install is tool-free: remove the cap, pop out the old spool, drop in the new one, line up the notches, and snap shut. Takes under 30 seconds.
• Common gotcha: the line may be slightly stiffer than OEM – if it doesn’t feed smoothly, pull a few inches out manually and re-bump the head. Avoid over-spooling (pre-wound is fine).
• Quality note: 1,000+ reviews at 4.4 stars – consistent feedback is good value, but some users report the line breaks more easily than OEM on tall weeds.

Should You Buy It

If you have one of the listed Craftsman battery trimmers and need a quick, no-fuss refill for light-to-moderate yard work, this is a solid, budget-friendly choice. Skip it if you’re tackling thick brush or prefer a heavier line – stick with OEM or a wider diameter.
