Okay, maybe not simple. Repetitive, though. I see you guys driving back and forth across a field all day.

With predictability I meant more like you have no idea when it will be wet or dry (for example), and everything depends on that. Sometimes you have to work hard pretty much as long as the sun is up, or at least that's how it was in my family's farming days. They would even eat on their tractors while they kept going. Other times it's too muddy to do anything.
