Worx 20V PowerShare String Trimmer vs Greenworks 40V 2-in-1 Trimmer Edger

The Worx GT Revolution is the more versatile tool: it converts between trimmer, wheeled edger and mini-mower with no tools, and it ships as a complete kit with two batteries, a charger and a 3-year warranty. The Greenworks 40V Gen 2 is the stronger pure trimmer on paper, with a wider 13-inch cut and a 40V platform, but it is sold tool-only, so you need Greenworks 40V batteries and a charger already. Owners of the Worx praise the light weight and the edging mode; the trade-off is a narrow 12-inch cut, a slow roughly 5-hour charge and a plastic build that suits suburban yards rather than heavy brush.

• Choose the Worx 20V PowerShare String Trimmer if you want one tool that trims, edges and mini-mows, and you want batteries and a charger in the box.
• Choose the Greenworks 40V Cordless 2-in-1 Trimmer Edger if you already own Greenworks 40V batteries and want a wider cut with more voltage.
