Junk- you are correct, but the manual states either UDT or SDT can use used. Based on the manual either one can be used and be 100% fine.
Unless Kubota makes a Global statement you can use either and be fine.
I also think you are missing the point here. It is up to the customer to select either one. Also either one is not wrong. So if I select UDT I can put in UDT or Amsoil. If I want to put in Super Duper UDT, I can only install Kubota fluid and not Amsoil.
Either fluid, no one is wrong since it passed either UDT or Super UDT. Does not state it must pass Super only for hyd.
If anything, the manuals sucks on this issue.
