I had a discussion with an engineer from John Deer, I'm not a farmer and don't have direct experience with it so I am taking his word but he told me in most cases the person in the tractor is just there to monitor what's going on for safety. I imagine this frees up people for other work if someone maybe less qualified can be in the tractor, or just takes the load off so they can work longer, allow them to do more in less time, etc.
