This Worx WG162 20V PowerShare 12" Cordless String Trimmer/Edger (Bare Tool) is the perfect tool for doing yard work. One of the best things about the WG162 is its a trimmer and edger; 2-in-1. In order to switch from one tool to the other, all you have to do is pull the head and shaft from each other and twist to turn the trimmer into an edger and then vice versa. It tilts about 90° so you can get under bushes and trim on sloped land much easier than most other trimmer models. The WG162 has the ability to extend as well to accommodate for taller users and when done goes back down; it also makes it more easy to store for off-season. This cordless string trimmer/edger contains a flower guard, giving you the leverage of being able to cut close to edge places without having to slice any flowers or other important plants on accident. The WG162 is compatible with the 20V PowerShare battery (Sold Separately).
