Hope this helps :)
The process of cutting and gathering a crop is called harvesting. The traditional implement used to harvest a crop is the sickle. Modern farms use a harvester, which cuts the crop. A harvester can be combined with other machinery that threshes and cleans the grain as well. It is then called a combine harvester or combine
After the crop is gathered, the grain is separated by a process called threshing. This can be done manually by striking the crop against a hard surface or by making farm animals trample over the crop.
A machine called a thresher is used to do the job in modern farms, else combines are used to harvest, thresh and winnow. Winnowing means separating the outer cover, or chaff, from the grain. It can be done manually, by dropping the grain and chaff from a height, and letting the wind blow away the chaff.
