A combine harvester is a massive machine that cuts wheat and other crops (like barley) in the fields at harvest time.
At the front of the combine is the ‘header’. It collects the crop with the reel which rotates and pulls it into the cutter bar which slices the stems off near their base. An augur brings the crop onto a conveyer belt which takes it up into the machine.
The threshing drum separates the stalks from the grain and the chaff is blown away by fans. Then the grain gets sieved and goes into a tank.
Then the grain is emptied out through the unloading pipe into a trailer on the back of a tractor.
