A true tradesman in his business. It's not about cutting one notch and cutting the other side. Then great tools, the tractor splitter separating the 4ft pieces was pretty impressive, then topped with the 8ft splitter, then the shredder kept getting better. What can be done with ingenuity, a small amount of hydraulic oil, a little hose and a piston is beyond limits. Crushing for a furnace or compost. when it can be made of plank or used for wood carving and the like. One is logs that are shredded, dried and combined to make wonderful resin-filled table tops. But these machines are monsters, I loved the one with the grinder when they fed it to the tree and it ate great.
