Other threshing machines would discharge grain from a conveyor, for bagging by hand. Combines are equipped with a grain tank, which accumulates grain for deposit in a truck or wagon. A large amount of chaff and straw would accumulate around a threshing machine, and several innovations, such as the air chaffer, were developed to deal with this.

A cotton picker at work. The first successful models were introduced in the mid-1940s and each could do the work of 50 hand pickers.
