Just about anybody who pays attention. The lawsuits have been ongoing for many years. JD303 is an ancient specification that even Deere abandoned long ago. Add to that the yellow bucket stuff is a really low end product made from leftovers and in some cases even line wash.Here's an interesting bit of info from Neil again.
Whodathought?
These transmissions do not require specialized oils and OEMs including Kubota do not make such an extravagant claim.This strikes me as a “which came first, the chicken or the egg?” situation.
Engines are designed to utilize the commonly available and distributed lubricating oils that the industry has settled-upon. Refiners know what to produce….Engine mfr’s know what to design-for.
Kubota (and others) often produce their engines for other purposes (i.e. marine, stationary, etc.)…. so they will all use an industry-standardized lubricating oil.
Hydraulic oils for hydraulic equipment using cylinders etc. are similar…and can use standardized fluids….but not in all cases for such things as HSTs.
Few HSTs are applicable to other purposes than the machine to which they are intended.
There are standards for hydraulic oils which HST mfr’s can design-to…. and there are mfr’s who have their own ideas for specialized designs …which do not accept the most-common hydraulic-oils …but which require specialized oils which the mfr’r specifies….some of which are “proprietary.”
Use something else at your own risk.
We are not on the same frequency at all.Are we on the same frequency today? Kubota makes several machines that specify “Super UDT2”.
Kubota promotes the use of Super UDT2 just like JD promotes Hygard and CNH promotes Ultraction. But nowhere have I seen any published requirement for the use of Super UDT2.
Please don't mischaracterize what I said.Exactly. Anyone who thinks that anything other than Kubota-branded fluid will destroy your tractor, or even shorten its life, is a guzzler of orange Kool-Aid.
There is no mystery and there is no magic in this stuff. Run something that meets the specs and you are good to go.
My local TSC manager is a working farmer and has run TSC oil in all her Kubotas for more than a decade with zero problems.
So hard the don't even try. he community does it for them.I would think it hard for Kubota to require SUDT-2 in all their machines...
I agree that there may be other fluids that may operate just fine in most Kubota equipment…
But MY M4700 Kubota Owner’s Manual is pretty specific…Here’s two screen shots directly from the manual:

Dan, I didn’t do anything for them. Those screenshots are KUBOTAs instructions.So hard the don't even try. he community does it for them.
Kubota promotes the use of Super UDT2 at every turn. Hardly surprising - it is their proprietary formulation and superior to almost everything else including their own UDT, The service section and lubricants table in my manual is exactly the same as yours but the notes section that follows the lubricants table is more specific. Is that bit missing from your manual? Does it not say UDT is also acceptable in the fuels and lubricants notes?I agree that there may be other fluids that may operate just fine in most Kubota equipment…

My manual does NOT allow UDT. It is specific…exactly as the screen shots show. (see my edited comments which were being posted as you replied.)Kubota promotes the use of Super UDT2 at every turn.

So the KUBOTA dealership told you the same thing I am saying but you insisted they were wrong. My manual has this section in it - is it missing from yours?Dan, I didn’t do anything for them. Those screenshots are KUBOTAs instructions.
<edit >When I got ready to do the 600 hr service on my M4700DT I went to the local Kubota Dealer (Ewalds) and asked for supplies. They first sold me UDT despite the clear instructions to use Super UDT. I queried the parts and service mgr’s very clearly and they were FIRM…that UDT or a UDT-compatible they also sold …was what should go into my tractor.
I’m not a “KoolAid” drinker so I was fine with that ….until I read the manual and the WSM specific to my model… and took the generic stuff back to them…and they again did their best to convince me to use what they’d already sold me….they said they’d show me it was OK and call the Kubota regional office up in Dallas…. when they returned to the parts counter with their hat in their hand and sheepishly took back the generic stuff and handed me the Super UDT2 and even discounted it very sharply to apologize.
YMMV
I just wanted to highlight a very important sentence in that post.Kubota | Lubricant & Grease Maintenance Schedule
Browse our Oil and Grease Maintenance guide for equipment lubrication involving grease and oil for Kubota's products. Learn more with Kubota service support.www.kubotausa.com
This is the most current table of lubricants for Kubota equipment. Operators manuals are notoriously out of date and one should always refer to the latest inline recommendations.
Notice I stated recommendations as Kubota cannot mandate the use of a specific oil in their machines. They can only mandate it meet certain requirements. Even Kubota states "recommended".
