1. A harvester for harvesting crops, the harvester comprising:
an elevator with a lower proximal end that receives harvested material and a higher distal end that dispenses the harvested material;
a spreader conveyor with a proximal end that receives the harvested material from the distal end of the elevator and a distal end that dispenses the harvested material; and
a secondary extractor that includes an inlet and an outlet, wherein the secondary extractor is coupled to the distal end of the spreader conveyor;
wherein the secondary extractor includes an extractor fan operative to create an air flow to pull air into the inlet of the secondary extractor to extract debris from the harvested material dispensed from the distal end of the spreader conveyor and expel the debris out of the outlet of the secondary extractor;
wherein the distal end of the spreader conveyor is positioned to dispense the harvested material into the air flow created by the extractor fan of the secondary extractor.
