Dad and I have been splitting 20 face cord each for over 30 yrs. He started with a 2 pt splitter behind a JD MT. Its hydraulics were not enough. So a 8hp used engine, coupling, pump and wheels were installed. Engine rebuilt a few times and finally replaced with a new engine. We always had loggers cords (102" long) delivered which works for his length of wood, 6 pcs at 17". I burn with an outdoor boiler which could take longer pieces. 102" cut with 3 cuts makes the pieces too long for the boiler, 4 pieces at 25/26" would work, but the splitter cylinder has a stroke of 24". Darn! So I cut 20" for 5 pieces. But the take away is what length of wood do you need to burn, and make sure the splitter can handle it. As far as 3pt or separate unit, which engine would you rather have a lot of hours added to it. I would rather run a $600 8hp engine than a $10,000 tractor engine. Yes another piece of equipment to deal with.
