I did not figure it out yet. I called my dealer, useless. Just told me they only use a Kubota third function kit. I tried reaching out to Kubota directly, no response at all. I looked at the loader valve and kind of have the flow path figured out, but there are unused ports on the loader valve that are plugged. I think one or more of them is a power beyond supply and a return to tank. One port on the bottom of the loader valve has a “T” on it. I wondered if that went back to the tank. I’d like to find a drawing with the ports on the loader valve labeled. I think I could “tee” in, but I’m reluctant to do it that way. I had called Summit about it initially and they didn’t seem that helpful about it. They recommended the universal kit I purchased and some custom hoses I would have to figure out later. The directions, of course, are very generic. I’m considering returning the kit and biting the bullet on the Kubota kit. It’s 3x more expensive.
