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]]. Far fewer people work in [[farming]] as a result of the combine harvester.<ref>{{cite book |title= A Century of Innovation: Twenty Engineering Achievements That Transformed Our Lives, Chapter 7, Agricultural Mechanization |last=Constable |first=George |author2=Somerville, Bob |year=2003 |publisher=Joseph Henry Press|location=Washington, DC |isbn= 0-309-08908-5 |url= http://www.greatachievements.org/?id=2955}}</ref> ==References== {{reflist}} [[Category:Agricultural machinery]]
