What makes you go to distrust? It is clearly about affordability. Someone who is currently running a 50 year old machine that is worn out and in need of replacement simply cannot afford a new tractor with all the modern bells and whistles. If they could, they'd have upgraded long ago. They
might be able to afford a new tractor that is built to 50-year-old standards, however.
Although, honestly, from my farmer persepctive I think that is even a stretch.
