For the price of a log splitter that has it''s own engine that you can tow or put in the trailer to take to the woodlot or even pull it behind the trailer as you move the setup to the woodpile it sure would be a lot less fuel and wear and tear on the roxor.
Pto's are primarily for winching, but there are times when an electric winch wins as they are just used in an emergency. I haven't used mine except for pulling others out lol.
Secret to electric winches is to have an extra strap and pulley. In a hard pull two parting the line and stripping line down so the winch is not as full it pulls harder and is easier on the winch.
After sitting on this for a while it occurred to me that putting a hyd unit driven off the crankshaft would be the answer. Would have to have a cooling unit in front of the radiator though, but would put out good flow. Hummers use the powersteering pump for the milemarker winch. For decent output though a larger pump and direct positive drive is needed. To me though, the effort and money sunk into pto and the valves, hoses, hyd tank and the rest of it outweighs electric winches or stand alone splitters.
