I can't think of why this would be unique to farmers, perhaps aside from a push towards autopilot systems.
Mining equipment, road building, all of that hyper-specialized stuff for slicing and dicing trees, I would think they all have this issue. Perhaps it's the greater prevalence of owner-operators.
I've probably bought the newest car I ever will (which is now 15 years old), so it would be nice to steer clear of the dealer-only craziness and the inevitable spying on you that new vehicles are going to accrue. I can just imagine how ticked I'd be if the tech juggernaut was messing with my income in a bad way.
