......... So the foaming has to be bad. I am running the new synthetic Kubota fluid. Maybe change to new fluid?
You might be thinking of the posts we had on that subject earlier. (posts #56 & #107...I think....)
At 200 hrs changed to SUDT. It didn't work well in my tractor and one of the problems was it foamed easily and took a long time to clear up. I did the same sort of test that you did. My hoe worked OK even with the foaming but the hydraulic pump developed a whine. Since the SUDT foamed so much I complained to the dealer and also wrote a letter to Kubota telling them about the foaming problem and asking them to check their oil themselves. Long story short: I never heard back from either one.
After not hearing any response for a couple of months I played a hunch and went back to using the New Holland Multi-G 134. That fixed my hydraulic problems.
BTW, my tractor came from the dealer with a mix of standard Kubota hydraulic oil and New Holland Multi-G-134. The Kubota oil simply because that is what was in it when new, and the G-134 because the mechanic spilled about half the original tranny/hydraulic oil when he changed the filter G-134 is what that particular Kubota shop carries as their bulk oil in drums, so that's what they put in mine. It worked fine for almost 200 hours until I decided I just had to try the SUDT.
