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.
Cotton is a significant cash crop. According to the National Cotton Council of America, in 2011, China was the world's largest cotton-producing country with an estimated 500,000 480-pound bales.
