Using the swing pump port for your
chipper is the best way as that is completely independent of the main pump and will not affect the 3 point lift or loader operation. I use the swing pump port on my
L39 to power rear remote valves for TNT when the backhoe is off. For something like a log splitter that can use higher flow you can use the main port but that affects the 3 point lift. Even if you pull the lever out to the backhoe off position, the three point will not get pressure as the plumping relies on the check in the quick disconnect to block flow out the rear main quick disconnect. You either have to disconnect the hose from the main port quick disconnect or what I do with my 3 point splitter is first extend the ram, then pull the lever to the backhoe off position. Then I bungee the lever on the splitter to the extend position. This blocks flow out the quick disconnect and allows pressure for the 3 point. Note that the flow is not deadheaded as long as the lever is in the backhoe off position it is flowing through the 3 point valve.
