Farmer Rob showed me a worn canvas ban that was replaced on the wheat thresher. By the looks of it, the band has seen a lot of revolutions in its day.
At different times, the wheat thresher will be powered by two nineteenth-century forms of power: animal power and steam. The draft horses will pull a mechanical gear, which powers a flywheel. And a steam engine will burn coal to produce steam, turning its own flywheel.
