The way I figure it, is that the dealership makes good money on the tractor sale, and continues to make good money on equipment, service, and repairs. What I would like, and I would think it should work this way, is to be able to call the salesman I bought the tractor from so he could act as my "go to guy" for equipment and service support.
If I were running a business, that's the way it would be. As Huey Long said, "Every man a king."
I still come back to the basic question - is the dealership limited to the number of new tractors they can get each year? If I buy a smaller tractor, is it really a punishment to them? Seems to me that if I order a tractor, they make good money just by filling the paperwork out - they don't have to carry the cost of the tractor while it's on their lot, etc.
The other thing I would have thought, in a depressed economy, is that tractor salesmen would be hungry.
