Hello , I'm Bobby .
You should have no problem running 2 hyd lines from your log splitter to your loader control valve hook ups. You should be able to just unplugged 2 lines say going to your bucket cyls and plug your log splitter hoses into there and lock your loader lever to have hyd flow to your log splitter control valve, Your log splitter control valve should be a open center control valve so you should not have any problems with your tractor running on high pressure.
