A fanning mill is a winnowing machine. Winnowing is the step of cleaning the grain to separate the considerable chaff, dust, weed seeds and whatnot from what you want to eat. Winnowing is done after the thresher knocks the grains loose from the head.
This hay lift carrier is attached to a pulley that lifts the hay into a barn through a door at the top of the barn leading to a hay loft where the hay is stored.
