A corn harvester is a machine used on farms to harvest corn, stripping the stalks about one foot from the ground shooting the stalks through the header to the ground. The corn is stripped from its stalk and then moves through the header to the intake conveyor belt. From there it goes up the conveying system through a fan system, separating the ...
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.
