I remember watching a YouTube video where a farmer was talking about how they are squeezed by modern tractors. I suppose any help farmers can get is worth the effort. I don't know anything about tractors, just read somewhere that farmers are looking more and more to purchase older tractors (without all the fancy software and electronics) - apparently those don't break down as much, and when they do breakdown, they are easier and cheaper to fix
