Hello; Amazing equipments. I wonder why they don't just use explosives instead of the long slow process of using a crane for demolition. It couldn't be that much more expensive to use explosives. Using stump removers is a bad idea in my opinion. For anyone that has actually removed many large tree stumps from the ground, you would be amazed to see how much tree material the tree root branches underground makes up. When these large roots eventually rot, the ground surface above sinks quite a bit. Anything you put on top, a roadway, building, bench or fence will have to be repaired after a few years.
