I looked at those units at NH. I don't care much for the design. They had the Powerhorse splitters on display alongside
this machine, which made them look like toys. As to their functions, there is no auto return valve, so you have to place logs from both ends of the machine, or run the wedge back manually. They only handle 19" logs, which may be all you need, but the majority of splitters seemed to be designed for something a little bigger.
You would hook the unit up to the
PTO QDs. You probably would not have to run the PT at full throttle.
