I really dont care how you feel about what I do or dont recommend. Dan

Your tractor has at least one rear remote valve. Before it goes to the dealer check all rear remote valves and make sure they are all in the center position. Dan

Good choice IMO but are you sure its Group IV.? Today most "full synthetic" engine oils are formulated with a large fraction of Group III+ base oil and and a considerably smaller fraction of Group IV. Not that I think it matters but knowing whats actually in that bottle of "full synthetic" is...

Your tractor is a M5660 - file that for future use. The knob only controls lowering speed and you had it closed off which prevents them from lowering. Thats now fixed. Lifting the arms and then they drop is 100% normal. So all thats left is why wont they lift. What other hydraulic equipment...

In 1999 Kubota published a SAE Technical Paper describing in some detail their development of a new high performance SUDT oil. They motivation they gave in the intro was the more demanding requirements of HST and powershift transmissions and they were focused on three things: Pumpability and...

Thats a super good answer. OEM's do not formulate their own oils. The develop perfromance requirements using industry test methods. They give those requirements to formulators who are free to use whatever chemical concoction they want as long as the finished oil meets or exceeds the performance...

Give it up. I have read dozens of those sheets. That is material safety data required by law. It is not lube oil performance data. Dan

Once agsan no. That is a safety data sheet. It lists the chemicsls that might pose a health or safety hazard to people or the environment. It has nothing to do with performance data. I can give you the data of interest but your mind is set and you are not interested in really knowng the...

That my friend is exactly Kubota's marketing strategy. UDT (Universal Dynamic Tractor) oil is as generic as it gets. SUDT is a low viscosity formulation with enhanced water tolerance. At the time of its introduction (1999) Kubota had lots of information on the new formulation. That wuickly...

Try again. That is a MSDS (required by law) not a PDS. Dan

The biggest "mystery fluid" on the UTTO market is UDT/SUDT2. Ever see a product data sheet for either one? Dan

Your pump is not pumping. Take the new filter off and see if its full of oil. My guess is its dry. Dan

You are tilting at windmills. Dan

I wonder if they consider that a two way equivalence. I would but what do I know 🙃 The FNHA and CNH specs are obsolete and more akin to UDT than SUDT2 Dan

Interesting list. I have never seen those specifications in any USA publication. In the USA its strictly SUDT2 and UDT. There are many products that are functionally equivalent to UDT including Traveler Premium UTTO ftom TSC. Personally I think the enhanced properties of SUDT2 is worth the...

Thsts not the way its suposed to work. Its also not uncommon. The valve and/or linkage is worn out and needs to be serviced. Dan

YouTube videos are way too often long miserable productions that could be condensed to 1/10 the length without any loss of the content the viewer wanted. Pictures are good (y) Dan

You need to do some simple testing to find the source of the problem. If the cylinders were opposed they would not work when switched to the boom spool. I think we can rule that out. Dan

No hands on knowledge but it Looks like a shift rail detent to me. They are often assembled by placing the ball and spring in the rail and depressing the ball as the rail is inserted in the housing. Whether you can do that without losing it inside the transmission is a function of your...
