My take is that the OP's dealer buys at volume discounts. The number of tractors a dealer moves makes a difference in what they pay to the factory for each unit.
I just spent over three months looking for a tractor - JD, NH, Case, Kubota, Cub Cadet... even Mahindra. I found two dealers that could sell at prices the other dealers in my area couldn't touch. One was in Shelbyville, TN (
CUB CADET YANMAR SALES AND SERVICE) and the other was in Douglasville, GA (
www.haneytractor.com). I literally bought a tractor from Haney for $12,000 less than what the local dealer quoted. Volume buying, plus getting a 2010 holdover accounts for the price difference. I asked the salesman there at Haney how come they could advertise such cheap internet prices, he said "we sell a lot if tractors, and we ship them all over the country because of our prices."
