shepp just be careful with how hard you push the splitter. alot of the old tractors will put out a good amount of pressure and volume just don`t lug it down to far because alot of the old cessena hydro pumps will take a beating but have no bypass valve, and aren`t made to keep pumping when nothing is moving under a load , so either set the bypass on your splitter valve alittle lower than the way it came ( prine valves usually state what the pre set bypass pressure is out of the box ) or just use your better judgement when splitting. ive built and setup a handful of tractor splitters, 2 used the backhoe outrigger pistons.
