Common questions

Questions before you buy

What is the cutting width of a 40V Greenworks string trimmer?

It varies by model. Greenworks ST40L213 has a 13-inch path; check the exact product number for other versions.

Does the Greenworks STBA40B210 include a battery?

Confirm the precise listing and model documentation before purchasing, since kits and tool-only packages can differ. Greenworks publishes model-specific manuals and package details.

Are 40V string trimmer batteries interchangeable between brands?

No. Battery systems are brand and platform specific. Follow the tool maker’s approved compatibility information.

How long does a 40V cordless trimmer run?

Runtime depends on battery capacity, vegetation, and operating conditions. Treat the manufacturer’s figure as a stated estimate, not a guarantee for every yard.
