A thresher or threshing machine is used to thresh grain, which is the act of separation of cereal grain from chaff. But nowadays, grain is threshed in a machine called a combine. A combine (combine harvester) combines the functions of several machines, hence its name. It will cut (harvest), thresh and winnow grain before storing it in a large hopper, which it can empty while moving and continuing to harvest. A link to the Wikipedia article on the combine is provided.
