If they had them all on demo, then bought the Deere because it was the best tool for the job, then that's fine. But if they bought the Deere because they have always run Deere, then they are indeed dumb butts.

I could, if you wanted, take 2 photographs, one of a field of wheat stubble harvested with a Claas Lexion, and one harvested with a S780i with all the toys, and you could compare the level of losses.
