> None of them are wealthy enough or operate large enough farms for expensive self-driving tractors. My father runs his own chopping business and his machines aren't automated or self-driven either. For him, it's all about being able to repair the machines himself. He's been a diesel mechanic and farm hand all his life, so if something breaks on a "traditional" harvester or tractor, he knows how to fix it and get it running again.
