When changing my fluids, I sticking to the Super UDT fluids. They are best for the Hydro transmission..... And engine oil, Kubota 30W or 15W-40 oil >>>>>>>></P>
We've all have paid a good price for the investment for a RTV's.... I don't mind spending a little extra to make sure it has the best !!!! After spending many hoursin research on the engine oils for these units, I will only go back in with the Kubota Fluids. I plan on keeping this machine for awhile. Even after the first of the year, we plan on purchasing another RTV, being a 1100 series unit, Still keeping the 900 for myself !!!!!!</P>
Figured if I can afford the price of the RTV's, I can afford just a few more dollars for quality oils .........As we all know, you get what you pay for, that's why we have the RTV's >>>RIGHT !!!</P>
