Kubota B3030 Hydaulics non functional when cold

[JJZ 109]

Thanks for all of your help. First thing I'll do is change the fluid and filters. What is the difference between UDT and SUDT?

I used this link when I first changed fluids/filters in my B3030: Kubota B-Series - Changing Oils and Filters

I also agree with the comment about finding a new mechanic if his knowledge thus far has caused you an issue like the one you're experiencing.
You may want to reread moship's post regarding AW32's recommended usages. Not sure if you can even get UDT at Kubota anymore. They may have gone to all SUDT or Super SUDT2, which I bought when doing my fluids.
If you're going to hang onto the tractor for any length of time, do yourself a favor and get in touch with Messick's and order a shop manual. Money well spent.

SUDT is what Kubota recommends in colder climates.

Flowerfarmer,

FYI... I'm not even certain UDT is available from Kubota or even SUDT. They are up to SUDT-2 now.

Here's some info on Super UDT: http://www.messicks.com/Articles/superudt.aspx

Kubota's Super UDT2: http://www.kubota.com/part/Lubricants.aspx

Please report back on your findings.

Here's some info on Super UDT: Kubota UDT/SuperUDT Specifications

Kubota's Super UDT2: Kubota Tractor Corporation - Parts | Kubota Lubricants

Please report back on your findings.

The Kubota Corp. page lists sudt2 and udt - no sudt. I'll take a trip up to the Kubota dealer and let you know what I find out.

Well, I finaly got to visit my local Kubota dealer. They don't stock Kubota fluids as they are also a New Holland dealer and have chosen to stock NH fluids. They sold me Ambra MG134 which is what they use in Kubota hydrostats, and the Kubota filters. After changing these out, all seems well. Thanks again for all of your help.:thumbsup:

Glad you are all set now :thumbsup:
