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.
Once cotton has been loaded into the module builder, a hydraulic compactor rises and falls along the machine's length. This action repeats every time a cotton picker is unloaded into the module builder until a complete module is assembled and released from the machine via its tailgate.
