A combine-reaper had several decks, which included: The main planting-and-reaping machinery just over the massive continuous tracks; immediately over it, the bins to storage the harvested crops and the packaging machines to process it; later, two more decks in the upper part with the living rooms for the crew; and last, a control cabin protuding in the upper deck. The aft part of the combine-reaper also provided an external landing bay so that visiting freighters could land directly in the harvester to collect the crops.
