I found this splitter for sale. It hooks up to a 3 pt. hitch and runs off a P.T.O. that drives a wedge on a jack-shaft back and fourth. Ever seen or used one like this ?? I have an electric splitter simular to this but I have never seen one that runs off a pto. The seller doesn't have a tractor to hook it up to, so I can't see it run. I wonder what it has for power.
