This is a two row cotton picker that is harvesting cotton in Belle Mina, Al. at the Tennessee Valley Research and Extension Center.
This is a six row cotton picker that is on display at the 2007 Sunbelt Ag. Expo. In Moultrie, Ga.
These cotton pickers have Global Positioning Systems (GPS) receivers installed on them. The small round object sitting on top of the cab of the cotton pickers is the GPS receiver. It receives signals from satellites in space that tell the farmer exactly where the cotton picker is located. This helps the farmer travel exactly the same path in the field when harvesting his crop as when he planted it. With the use of this technology, the cotton picker machine is also able to drive itself along a straight line made by the computer system and never be more than a few centimeters off at any given time.
Cotton pickers are also equipped with a yield monitoring system. This system measures the mass flow with sensors and gives the farmer an accurate measurement of how much he is harvesting from his fields.
The yield monitoring system and GPS can be linked and a yield map can be generated illustrating the yield across the field. This feature will help the farmer know exactly where to fertilize his fields the next year and where he can save his money and not fertilize.
