Hi Dale, I have also heard 250, but the number I was told by one of my sources in Italy was around 200. Unless the original manufacturer steps up, we probably will never know. Often tractor production doesn't start with 001 so tractor numbers don't mean much. They could have easily started at 100, 200 or 300. At any rate, the tractor wasn't successful and there are not many around which is why I advise owners to find another for parts. We can supply parts for the Slanzi diesels, but the rest of the tractor presents challenges.
