I'm betting autocycle valve for the splitter is why you see 4 levers.I only see 3 cylinders but 4 valves. What are you using the 4th valve for, hot corffee? Nice build and good touch on the draw bar. Have you tried any really heavy rounds on that lift? The wheel base looks a little narrow compared to the overhang of your lift. Might want to do a little tests with it to make sure she's stable.
Nice looking splitter Goat. Now mount you a winch and ramp to pull logs up to the splitter and a good chainsaw to buck them with and you will have a decent processor
