oh, as for the oil I use rotella T (full synthetic) and i get it from walmart in a gallon. As for the trans, i had to get the filter and fluid from the dealer. I wanted to put the sudt fluid in the trans but my dealer said we dont even carry that stuff because thats only for extreme temps and not needed in NJ. They use udt fluid in everything and they rent their machines out too.
I was in advanced auto the other day and they had a few different hydraulic fluids, one made for farm/tractor use and it said on the back it was kubota approved, which i thought was weird. I dont know much about hydro fluid, and i am sure their isnt much of a difference, but with that, i will stick with udt from the dealer. Like the previous poster said, use oem to be safe if you dont know. But with the filters and oil i researched and know whats for what and what can be use else where. I like to get the best protection I can get. You have to reasearch and learn about the oils now a days, they have a lot of additives for different things.
I just try to use whats better, so if i have to do a little running around for stuff i dont mind. The funny thing is all my bikes use the same oil filter so i stock up on them. I also run the same oil in them too, rotella t. So have that on hand too.
