Just purchased a used 2015 Kubota U 25 1770 hrs..
Looking for info and was directed to
the Kubota S series.
Wondering if the S series is just a later production?
What are you trying to find on the U series Mini Exs? They have the KX series (reg tail swing) where as the U is the min. tail swing. I don't know of an "S" series, perhaps it is an overseas version?
