I previously had the 12 volt gras hog unfortunately it was a bit too light weight for my taste. I have since upgraded to the 18 volt Grass Hog and I am so happy with the performance of this machine I now have six of the 18 volt cordless tools. The Fire Storm line uses the same batteries. There is also an 18 volt Dust buster.
Black & Decker 18 Volt 12 in. Cordless Grasshog Trimmer/Edger is recommended by HogHaulers
Cordless electric trimmer provides hassle free trigger starting along with an adjustable auxiliary handle which adjust to user's height. A AFS™ system uses centrifugal force to automatically advance line when needed. 12 in. cut path cuts more area per charge than other cordless trimmers. Groom N' Edge™ converts from trimming to edging with the touch of one button. Includes two batteries.
