§ FAQ

What is the QUICKWIND spool system on the CMCST920M1?

QUICKWIND is CRAFTSMAN's spool loading system that lets you reload the 0.080-inch twisted trimmer line faster than a traditional manual-wind spool. Instead of threading line through a small hole and manually winding, QUICKWIND simplifies the reloading process to reduce downtime when the line wears out.

What does a brushless motor mean on a string trimmer?

A brushless motor draws power more efficiently per revolution, runs cooler over extended sessions, and maintains consistent line speed as the battery drains. For a trimmer used weekly on medium-to-large yards, the efficiency advantage translates to more trimming per charge compared to a brushed equivalent.

Is a 13-inch swath meaningfully wider than the 10-inch in the CMCST915 series?

Three extra inches per pass adds up over an entire yard. A 13-inch swath reduces the number of passes needed along a long fence line or across a large lawn perimeter. On small yards with mostly tight spots, the difference is minor; on larger borders, it saves time.

How does the CMCST920M1 compare with the brushless RP CMCST930P1?

The 920M1 uses a standard brushless motor with a 13-inch fixed head and QUICKWIND; the 930P1 uses a brushless RP motor and an adjustable shaft. The 930P1 is CRAFTSMAN's top-tier trimmer with more sustained cutting power and ergonomic adjustability. The 920M1 is the mid-range brushless option at a lower price point.

Does the CMCST920M1 come with everything needed to start trimming?

Yes. The kit includes the trimmer, one 4Ah V20 battery, and a charger. Add replacement trimmer line when the included line wears out — the model uses 0.080-inch twisted line.
