Harvesting machines

Headers harvest crops such as wheat, barley and oats. These machines are also known as combine harvesters. Headers combine the three operations needed to harvest a crop -- reaping, threshing and winnowing.
The comb on the front of the header cuts the heads off the stalks (reaping). The auger pulls the heads into the machine. The stalks left standing in the paddock are called stubble.

Threshing involves separating the grains from the head. The drum rotates, beating the heads. Straw and chaff (bits of stalk) are fed out the back of the header. Straw is spread over the ground. Stock can graze on this and the standing stubble left after harvest.

There are a number of screens in the header. Grain passes over these and fans blow the husks away. This is called winnowing. The clean grain is stored in the box. When this is full the grain is augered out into a chaser bin or truck.
