4 remotes (4 X supply and return) or 2 sets of remotes (2 X supply and return)? They only make a kit to add a second remote to the tractor so if there's actually 4 sets, they're using something else to do it. Why only 6 month warranty if it was just sitting on another dealers lot? Is that a warranty from the dealer or the balance of the factory warranty? There must be more story to it than it was on another dealers lot, it doesn't matter how old the tractor is, if it doesn't have an in-service date (never sold), the full warranty would apply.
Regardless of any of the above, it still sounds like a great deal. The difference between Kioti, Bobcat, Landini and McCormick other than the color, warranty and price is they all use different loaders. I know nothing about McCormicks loader (or who builds it for them) but I'm pretty sure I've seen pictures of a CK27/30/35 (all the same loader) moving a round bale. Try a search in the Kioti forum.
