Our take on the Black+Decker 40V MAX 13 Inch String Trimmer and Lawn Edger

The Black+Decker LST140C is a cordless 40V string trimmer that converts to a lawn edger without tools. It uses Power Drive high-torque transmission for stronger cutting at the string and an automatic feed system that advances line without bumping. A state-of-charge indicator on the battery shows remaining runtime, and the charger mounts on a wall. It suits homeowners with small to medium yards who want one tool for both trimming and edging and don't want to deal with gas or cords. Against 18V and 20V trimmers it cuts heavier grass, but it is heavier and bulkier than those lighter models, and its 13-inch swath is narrower than many gas and larger cordless trimmers.
