Just be very careful on sending money before you (or someone you trust) see's the iron. Many auctions (esp. ebay) for tractors are scams, and if the deal is/was to good to be true, it probably isn't...
I was playing with one scammer one ebay and 'won' a great deal. He had even set up a web page for an escrow service that he wanted me to use... with a phone number, email, and live chat available to help with the escrow transaction. It sure looked like a valid business.
Good luck,
Eric
