Since hand labor is no longer used in the U.S. to harvest cotton, the crop is harvested by machines, either a picker or a stripper. Cotton picking machines have spindles that pick (twist) the seed cotton from the burrs that are attached to plants’ stems. Doffers then remove the seed cotton from the spindles and knock the seed cotton into the conveying system. Conventional cotton stripping machines use rollers equipped with alternating bats and brushes to knock the open bolls from the plants into a conveyor. After harvest, most of the cotton is now pressed into modules in the field for storage. These modules are then transported to the cotton gin for removal of seed and trash.
