Agricultural harvesting machine with a multiple stage compression system

An agricultural harvesting machine having a multiple stage compression system comprising:

• a pickup mechanism which gathers a crop material from an associated ground surface;
• a first compression system including a first compression mechanism which partially compresses the crop material in a compression chamber received from the pickup mechanism;
• and
• a second compression system including first and second compartments each having at least one open end and positioned rearward of the compression chamber, the second compression system having a first position in which the first compartment is aligned with the compression chamber to receive the partially compressed crop material and the second compartment is operatively positioned with a second compression mechanism, the second compression system having a second position in which the second compartment is aligned with the compression chamber to receive the partially compressed crop material and the first compartment is operatively positioned with the second compression mechanism, and the second compression system including a binding system operatively associated with the second compression mechanism, wherein at least one of the first and second compartments rotate between the first and second positions.
