††††The combine harvester, or combine, is a machine used for harvesting cereals and other crops. it gets its name from the fact that it combines the actions of cutting the crop (reaping) and separating the grain or other seeds from the plant (threshing).
Samuel Lane patented the first design for a combine in 1828, but it took a hundred years for them to become popular. These early combine harvesters were drawn by horses and then, later, by tractors. Self-propelled machines were developed during the 1940s. Modern combine harvesters are self-propelled by huge diesel engines, They are capable of cutting a swath 9 metres or more wide.
