I bought a 3 point hitch mounted log splitter. I need to know how to hook it up to my tractor hydraulics. The tractor has a loader. I disconnected two hydraulic lines at the loader valve and re attached them via quick disconnects. I put mating quick disconnects at the splitter. The idea is to disconnect from the loader valve and plug the hoses into the the splitter whenever I want to use it. I took the "in" from the pump to the loader valve and plugged it into the "in" port at the splitter. I took the line that went back from the loader valve to the oil reservoir and attached that to the "return outlet" port at the splitter. The splitter worked, sort of, but the 3 point hitch lift is disabled as well as the loader now. There is a third line that might be the right one. Its called "power beyond". I'm wondering if that's the one to plug into the splitter return port. Anyone know how to do this?
