The primary combine I run doesn't have autosteer or a preset header heights and has a rigid header/sickle. If I run my neighbors and help him finish out his machines do. And they're just presets and generally only useful on flat ground or terraces that are very low. Flex headers have a flexible floor and sickle and can just conform to the ground if needed. Most farms I can't use it, but it's awesome when I can use both. Still have to watch where you're going and what's in front of your header though when using those, it's not totally dummy proof.I'm still wondering how a combine working with GPS and satellite imagery keeps from putting a header into the ground on uneven ground.
Sorry, but if I were doing it again today, I'd have to insist on being in total control.
