A bean harvester, also known as a bean thresher or bean combine, is a threshing machine which is used to harvest beans. It mainly consists of a pickup, several beaters, shakers, one or several fans, elevators, conveyor belts, a storage bin, and usually a spreader at the rear. Until recently, the only practical manufacturer of bean harvesters was The Bidwell Bean Thresher Company.
