So, imagine a SUV being drawn by eight teams like that. I usually call that shot "Why we build motors" - look at that tiny sickle bar! It took only about 10% of the power. Around here, separate threshing machines were more popular, running from wood or coal fired steam engines. The first "field engines" look like tractors, but were really just self-propelled, sometimes towing the thresher on easy ground. The early gasoline tractors had their cooling systems designed and built by redundant steamfitters, with air passages like fire tubes.
