A reaper is a farm implement that reaps (cuts and often also gathers) crops at harvest when they are ripe. Usually the crop involved is a cereal grass, especially wheat. The first documented reaping machines were Gallic reapers that were used in Roman times in what would become modern-day France. The Gallic reaper involved a comb which collected the heads, with an operator knocking the grain into a box for later threshing.
