ZD21 50 HR Service Questions

[BHarrison]

Well, it's that time. I have a few questions for the group.
The Manual calls for 10W30 in my temperature range. It doesn't even mention 15W40. Have we decided whether or not Kubota oil is any better than RotellaT? What about the Rotella Synthetic? Has anyone had any experience with it?

...I guess my questions are mostly oil related. I noticed that the manual calls for a hyrdo filter change (only) at 50hrs. I believe I've read from some folks that have changed their fluid at 50hrs. Is this necessary?

Thanks

On every Kubota hydro tractor I have heard of, it is recommended to change fluid at 50 hours. I don't know about the ZD, it might be worth a call to your dealer's sefvice department.
