I also grew up in a rural high school with a large farming population. I categorize farmers into three types:
1. Professional - Usually highly educated, good business sense. Probably obtained an advanced degree in agriculture science, though not always, some self-educate very successfully. These farmers generally do not like John Deere and think they are overpriced, not as good as they once were, and find the lack of right to repair infuriating.
2. Uneducated - Likely barely passed high school due to a complete lack of effort, because they were going to be farmers and school, "couldn't teach them nothin." Farming is an identity for these individuals. Buying a John Deere is part of that lifestyle. Some kids grow up with a Ferrari on their wall, these kids had a John Deere tractor. The problem with these individuals as it relates to business is that they do not understand business or accounting and probably only have a rudimentary understanding of ag science. They overspend on equipment and their only basic ag science understanding leaves them unable to adapt as well as the pros to droughts, infestations, and other adverse conditions.
3. Gentleman Farmers - Usually educated, but perhaps in an unrelated field. Farming is a hobby. Perhaps a retirement "job." If they make money, great, if not, well, they have money to spare. They buy John Deere, because they can afford it and because it seems like the obvious choice. They are happy to pay their local dealer to fix or repair their tractor, it is something they don't have to worry about and costs are not a real going concern. Breaking even is a success.
Both the less educated farmers and the gentleman farmers treat John Deere tractors as a status symbol (every other farmer know exactly how much a John Deere tractor costs). And when you know how much they cost it is like seeing someone drive by in a Ferrari or Lamborghini, because, well, they cost as much as a Ferrari or Lamborghini, if not more. The professional farmers could care less because they are running a business.
