Rat,
JD has the loader hydraulic valves on the tractor as well as the stick. My understanding was that Kubota had a stick you could mount to the tractor's fender that controlled the valves by cable. I thought the valves were on the loader sub frame, which is why they would come with the loader, not the tractor. Is that wrong?
You're clearly right about the kubota controls staying with the tractor. Even on my 2710 the control lever is mounted to the sub-frame, and the hydraulic lines hook up right in front of it. The sub frame is always on. On the 4610, if you can mount the control either to the sub frame to the right of the wheel, or on the fender, is there a difference in feel or precision between the two sites, because of cable slack or stretch?
