After loading the cotton into the module builder, a hydraulic compactor moves up and down along the length of the machine. This process is repeated every time that a cotton picker is unloaded into the module builder until a module is built up and discharged through the tailgate of the machine.
The process of building modules involves loading cotton into the module builder, using a hydraulic compactor to compact it as it moves along the machine's length. This process repeats each time a cotton picker is unloaded into the module builder until a complete module is assembled and discharged from the machine via its tailgate.
