Figure 4


Fig. 4. An early stationary grain thresher powered by 12 horses. Note the conveyor system at the back of the thresher for elevating straw to the top of the pile. Steam engines had almost completely replaced horses to power threshing machines by the turn of the century. Photo from Brumfield (1968).
