Ever seen a PTO Splitter like this ???

I found this splitter for sale. It hooks up to a 3 pt. hitch and runs off a P.T.O. that drives 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 of 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.

How does it reverse? I can Fathom it screwing in to split the wood, but not how to get it back out. please splain (if you know)

Do you see the lever sticking up? I think there is a belt and pulley set-up that changes directions when you pull or push
