I took delivery of my new CT 230 and there are no dates on any of the serial number tags. The dealer did show me the factory invoice for the tractor but it just had a ship date on it not a build date. The tractor was delivered to the dealer in April of 2010 and I bought it in December before the promotion ran out. The dealer added the newer Bobcat front loader to the tractor and I ended up with the 62" bucket which is fine. When back dragging it just covers the tracks of the R4 or general purpose tires. I got a bill of sale and I it is insured under my homeowners policy. It's mine now. I don't have any attachments yet but since I am just pushing snow with the bucket for now that's OK. The hydro. is a bit noisy when cold but tolerable. I looked at, and sat in many other tractors, Blue, green, red and orange. Each had it's pros and cons but the value for the buck and features of this tractor led me to it. I paid $15,370 for it so far I am happy. Time will tell.
