Questions before you buy

What does a 3-in-1 cordless grass trimmer do?

A 3-in-1 design combines string trimming with other lawn-edge tasks. BAUER identifies trimming, edging and mini mowing in its 20V model; Greenworks offers a trimmer-to-edger conversion.

Is a trimmer, edger and mini mower the same tool?

They are different functions. A multifunction model changes configuration for each task, but its cutting width and head design still determine where it works best.

Does the Greenworks 40V trimmer convert to an edger?

The 40V 13-inch Gen 2 model is described by Greenworks as a trimmer/edger and its head converts for edging.

Does the BAUER 20V 3-in-1 trimmer include a battery?

No. The listed BAUER 19115C-B is tool-only, so its compatible battery and charger must be acquired separately.
