Hello; The first one was worthless. The second one is the real deal but dam are they spendy. Guys at work did 8 k worth of damage to a much smaller machine. It is just amazing what it takes man to just tame a few years of growth from mother nature. Imagine watching a glacier collapse, and then seeing a man made technology demonstrating ways to destroy nature, what the fuk are they thinking? The machine in the beginning of video has absolutely destroyed the looks of our wooded areas. They use it all over our county and it looks awful when you are driving down our roads. They also bring it into our subdivisions and butcher the roads.
