I live in corn country and my house is surrounded by crop fields on 3 sides and it faces a small woods. I was mowing and mulching leaves today while they were combining the corn field next to me. I know the farmers fairly well and I asked the one driving if he cared if I rode a while--he said climb in and I rode near 2 hours, If any of you get the chance to ride in a new John Deere combine anytime I would advise it, first it is amazingly quiet, we carried on a conversation at normal range with no problem, total climate control cab, almost all glass for viewing ease, I was on the buddy seat next to the operator, it was very comfortable.monitors everywhere, he was actually driving today because it was the last field and he wanted to, all of the previous crops were picked by automatic steer--it is a gps based-and sensor in the head guidance system that steers itself through the fields, you just have to turn around on the ends. It picked 12 rows at a time, the corn was planted with the gps guidance system also. They are not huge farmers by todays standards but 3 of them farm around 2500 acres. He thought the corn field would average over 200 bushells to the acre we were in, pretty good for a dry year. Farming has vastly changed from 40 plus years ago when I worked on my uncles farm. The price tag on the combine I was in was in the half million range.
