It's not mine, but
I get to use this one belonging to my stove dealer/log supplier. It's a 35 ton Faver, with a wonderful hydraulic lifter and a good 40" throat length, plus a hydraulic 4-way.
I don't have a lot of experience with other splitters but I know this one is pretty impressive when he can hoist a 48" diameter stump up with his truck picker and the splitter busts it up with little effort.
I so think Butch's is the best looking machine posted thus far though.
