For farmers today, the choice is more stark.

I can only speak to small and medium farms, but if we're talking large horsepower cultivators / row farming, It's really a choice between keep my old pre-emissions diesel/buy a pre-2006 used tractor from auctions/marketplace for 50k, or double down and lease a 250k-400k new mid-size tractor.

You make it seem like many farmers have choices, but old "dirty" tractors are the only financial options for many without signing up for indentured servitude to JD/Case/etc
