CMZST260H Trimmer Head Replacement for Craftsman 20V 60V CMCST920 CMCST960 Quickwind Weedwacker Series Cordless String Spool Trimmer

What It Is

This is a replacement trimmer head assembly for Craftsman cordless string trimmers, specifically designed to fit the Quickwind series. It holds and feeds trimmer line for edging and trimming grass/weeds in residential yards.

Fitment & Compatibility

Directly replaces the OEM head on Craftsman 20V (CMCST920) and 60V (CMCST960) models. It also fits the CMZST260H and other CMCST-series trimmer part numbers. Before buying: verify your trimmer’s model number (on the battery compartment or underside of the shaft). This is a non-OEM aftermarket part—it may differ slightly in plastic color or texture from original. Measure the head diameter (approx. 10–11 inches) and check that your existing bump-feed mechanism matches. Not compatible with gas trimmers or other brand models without adapter.

Key Things to Know

• Installation is tool-free: remove the old head by hand (left-hand threads on some models), then screw on the new one. No adapters needed.
• Line loading: uses the same “Quickwind” system—push line through the eyelets and wind manually. Some users report the spool may be slightly tighter than OEM, requiring extra care during loading.
• Durability: rated 4.3 stars, but a few reviews note the plastic housing can crack if you hit hard objects (rocks, curbs). Avoid impact.
• Common gotcha: ensure the head is threaded on fully and tightened clockwise (or counterclockwise for left-hand models) to avoid wobbling during use.

Should You Buy It

If your Craftsman 20V or 60V cordless trimmer’s head is worn, cracked, or the bump-feed stopped working, this is a cost-effective fix at ~$16. It’s a direct swap for DIY homeowners, but if you need OEM color match or maximum impact resistance, consider the original Craftsman part.
