Kubotaone: Did you use the recommended Super UDT for the transmission/hydraulics, or did you use Kubota UDT? The owner's manual "highly recommends" the Super UDT, but in checking with my selling Kubota dealer parts dept, they first told me that the Kubota UDT was the same as the Super UDT, then when I argued with them, the parts mgr. admitted that there was such a product, but they didn't stock it because everyone was using regular Kubota UDT. When I pushed them, they said they could order it, and they're charging me $82 for a 5 gallon pail, plus $8 shipping. Am I missing something? Why would they not recommend a better product based on their mfr's recommendation, and why would they not want to sell a more expensive product to me if that's what I want? It's kind of like the difference between using regular Mobil motor oil and Mobil 1. As far as I'm concerned, the Mobil 1, which I run in everything I have, is well worth the extra cost. So why not use the best trans/hydraulic fluid available? What's your thoughts on this?
