This is a heavy-duty, walk-behind string trimmer that is powered by a gasoline engine. It has dual string trimmers underneath, each with the thickest, strongest string that you can buy. Comes with the user manual and an almost-full spool of replacement string.
It is designed to hack down the toughest stuff in the field. I bought it last year to hack down the ferns and stuff in the field behind me to create.a better fern garden. It worked pretty good, but I decided I didn't want to do this every year, so I'm putting it up for sale (as well as the tiller shown in the background).
