The Black & Decker 18-Volt Cordless Grass Hog Trimmer/Edger puts the finishing touches on any lawn or garden. There are no extension cords or gas engines to maintain, and the light weight adds to simplified operation. A large 12-inch cutting path covers a lot of groud in a single pass when trimming, and the tool offers deep, defined borders when switched over to edging. Black & Decker?s patented gear drive transmission delivers the most power and cutting performance of any cordless trimmer in this voltage class.
