Universal and general rule. Best time for tractors, as some said, is winter time, between 10th month - 2nd month. Every items have seasons. Off-season time, you can get a better price if you know how to buy, how to negotiate. There is a guy here. He earns his life by buying items during their off-seasons only. He deals many different items, he even buys summer cloths during the winter and sells them when the summer comes. He buys plows early summer and sells them next year. I think he is making some good money, at least 15-20% average profit. Better profit than investment on interest and stock market, and safer investment. Cloths, plows, etc are always needed items.
