Combine harvester

A combine harvester, also called a combine, is a machine that harvests crops. Its name comes from doing three separate parts of harvesting crops at once:

• reaping: cutting and collecting crops when they are ready for harvesting,
• threshing: separating the parts of a crop that can be eaten by people from the parts that can't.
• winnowing: removing the already separated parts of the crop that can't be eaten by people, the chaff, while keeping the part that can be eaten, the grain.
