I just posted this in another thread:
I'll repeat it again...
I own two Kubotas a BX2370 and a L2501, I run 80-90 synthetic in the front diff, Rotella T6 5-40 in the engine. The hydraulic system I DO NOT run sudt2, the salesman and two mechanics told me to run this, it specs the same as the Kubota fluid (they wouldn't /couldn't) tell me who actually bottles the Kubota fluid. I set a email to this company asking if it was 100% truly sudt2 approved. He replied absolutely 100% that is. He then sent me the full msds and chemical analysis of his oil and the bottled Kubota oil. They were 100% identical and he stated when they are blended there is nothing different as they come off the line. <hint #1, he said they do get put in different colored jugs <hint #2, one last thing the said is that if you were to have a fluid related failure you will be 100% covered as this is the factory fill <hint #3. I flat out asked him if they supply the Kubota fluids. In very plain in company speak he said, "I can't tell you if we do also I can't tell you we don't."
I believe this it the supplier of the Kubota fluids.
