Forgot to add...I emailed with the seller today. He had two updates done by the dealer in November. I'll know more this weekend when I take a look at the machine.
Just to add to the mix, the Kubota dealer called back this evening to let me know that they have some brand new tier 3 cab 75's coming in this week. Apparently Kubota is sending a few leftover units to their top dealers nationwide. Tempting.
