Cotton is machine harvested in the U.S., beginning in July in south Texas and in October in more northern areas of the Belt. Stripper harvesters, used chiefly in Texas and Oklahoma, have rollers or mechanical brushes that remove the entire boll from the plant. In the rest of the Belt, spindle pickers are used.
Before the cotton gin, cotton had to be hand-carded, to try to get the seeds out of the cotton bolls. This was a â¦ slow, labor-intensive process, and cotton was not a popular crop. After the cotton gin, the bolls could easily be deseeded, and cotton quickly became a staple crop of large scale plantation operators.
