I have seen small versions of the wheel grinder in action but that big wheel monster that was grinding the stumps is the fastest grinder I have ever seen, this has to be one of the best on the market. I am sure the cost is way up there and a company would have to be able to do a lot of Stump Work to pay for it.The first uninstaller is crazy. A really powerful wood splitter can weigh from 40 to 50 tons. That's like 200 times that.
