Provided is a harvester capable of promptly executing a sorting and storing process of crops without being affected by a measuring time by a quality measuring unit. A harvesting unit (2) for harvesting crops in a field, a grain tank (4) for storing harvested crops, and a control unit (50) for controlling grain storage position changing means (38A to 38C) of the grain tank (4). The combine 1 provided, the control unit 50 includes: a map obtaining unit that obtains map information that associates a position in a field with a quality classification of a crop； a current position obtaining unit that obtains current position information of the combine 1； The system includes a quality classification determining unit that determines the quality classification of the crop to be harvested based on the current position information and the map information, and a classification storage unit that classifies the harvested crop for each quality classification and stores the crop in the grain tank 4.
