Kubota G1800 transmission fluid?? Help!

[michauxii]

What transmission fluid to use in this rider/mower.

The Kubota came with the place I bought, but without an manual.

The guy at NAPA seemed to know this model and sold me a 5 gallon bucket of tractor hydraulic fluid.
I changed the filter and added fluid. Checked the dipstick while hot and cold.

Tractor barely creeps. Something ain't right!

Ned some help/input fellers!!

Kubota would use UDT/SuperUDT. It should move though with a standard hydraulic oil.

Yep.. Right filter! It's a kubota filter with the same,exact numbers etc.

I think I probably have air in the system...I've looked for some type of "bleeder valve" and can't find anything- that does NOT mean that there is not one that I've overlooked!

How would you go about purging air from the transmission system??

Thanks!
