The module builder has helped to solve a logistical bottleneck by allowing cotton to be harvested quickly and compressed into large modules which are then covered and temporarily stored at the edge of the field.
[1] Module builders are also widely used in other countries where cotton is mechanically harvested.
In 2002 the ASABE (American Society of Agricultural and Biological Engineers) dedicated the cotton module builder as an historic landmark of agricultural engineering, naming it "one of the top three inventions in mechanized cotton production.
After loading the cotton into the module builder, a hydraulic compactor moves up and down along the length of the machine.
