If it has four wheel drive, and the cab is the Kubota Ultra, then with 4-in-1 and quite low hours the value should be up in the $25k+ range, maybe more if clean-garage-kept, another upward tick with hydraulic shuttle. With 2wd it might be $3-4k less, and a lesser cab than Kubota would lower it too. Are you buying or selling? As always, prompt cheerful refund if my guess is bogus.
