Once the grain has been separated from the chaff it is 

stored in a tank in the combine. When the tank is full the 

grain is emptied into a trailer through a pipe called an 

Inside the pipe is a

which moves the grain up the tube. A screw is simply a 

spiral blade around a shaft. As the screw turns it pushes 

the grain up along the tube.

The edible 

grain

 portion of crops such as wheat, corn, barley, and rye are 

covered by an inedible casing called 

chaff.

 To use the grain it has to be 

separated from the chaff. Before the use of machines this was a very labor 

intensive process. The combine harvester gets it’s name because it combines 

three processes in preparing grain crops: 

The first step in the process is to cut the 

grass when it is ripe, called 

 At the 

front of the combine harvester is the 

,

 which gathers the plants into the 

combine. Behind the header is the 

which functions like a giant electric 

razor and cuts the base of the plants. 

The next step is to remove the head of the stalk and 

loosen the grain from the chaff by

 which is 

accomplished by hitting the grain against a surface. In 

a combine harvester this is done by the 

 The threshing drum is a cylinder with large bars 

that hit the grain as the cylinder rotates at high speeds.

The grains is finally separated from the chaff by 

 Under the threshing drum the grain and the 

chaff move over a grate. Air is blown through the chaff 

and grain, and the heavier grain falls through the grate 

while the chaff is blown towards the back of the combine.
