I recently read that the big suppliers of farming equipment have divided the land so to speak and aren't operating on each other's turf. You buy from whoever has a functional supply chain in your part of the farmland; if your tractor breaks, you need to get it fixed quick, because nature doesn't wait. Can't wait for some small startup or chinese supplier to send parts or technicians from the other end of the country. It smells like a cartel to me. Either way, it doesn't seem easy to compete in such a space.
