IA has one of the best Threshing shows in the mid west. Very interesting to see how it was done "back then". I am humbled to admit that I am very familiar with grain binders and threshing. There was some of that still going on when I was a kid. Most, including us, had moved on to combines(JD 55), meaning combination reaper/thresher. Some of the old timers still used what they had. Lots of small family farms and dairies then. Usually neighbors pooled their resources to get the job done. We had a New Holland baler so guess what, we baled a lot of neighbor's hay.
