How combine harvester works?

About 200 years ago, 90% of the world's population relied on agriculture. So at that time the employment is only from farming and almost people doing farming. But nowadays almost 25% of world population is depending on Agricultural. What caused that amazing change in society? One important factor was the development of huge, automated machines such as combine harvesters that made each agricultural worker vastly more productive. Let's take a closer look at how combine harvester works?

Working of Combine Harvester

A combine harvester is used for harvesting cereal crops. At the front, a rotating pickup reel forces the crop against the cutter bar. A rotating screw feeder carries the cut grain onto an elevator, which carries it to the fast-spinning threshing cylinder. This separates the grain from the straw. The grain is off-loaded into a truck and the straw is ejected from the back of the harvester on to the ground.
