In America's orchards and farm fields, the constant struggle between hand labor and mechanization has produced dozens of efficient and sometimes bizarre harvesting methods. Learn the secrets of the orchard manager and his ladder crew as they check fruit pressures and barometric readings. Visit California's largest fruit packing house and try to keep up with 10-fruit-per-second conveyors. Then off to the corn fields of Nebraska and the cranberry marshes of central Wisconsin. Finally go underground to the world's largest mushroom farm where the harvest takes place in limestone caverns that run some 150 miles. From fruit tree picking platforms to cranberry beaters and corn pickers, farmers constantly strive to speed the harvest.
