those are worthless. they leave shitty cuts all over the hood. ive seen one work first hand and they are sllloooooowwwwwww! not to mention dangerous. i can remove or trim{without an incident} faster from a bucket than a giraffe can....and keep it up all day. you still need a groundy. the only exception.....cut bigger pieces faster.....but they look like hell after. they are just for the companies trying to save a buck. they might be useful on transmission work where the trees are larger and farther back and where they are not as likely to b e seen. they d be cool to fight against a giant stump grinder.
