The header on a combine is the part that cuts the grain. Corn takes a different head than other grains. Here's a picture of what a corn header looks like (in the first photo) When it's running the header can move up or down depending on how high the corn is on the stalk. The corn is planted in rows and each row goes in between the parts that point out when the stalk is jerked down and the ear is pushed off and into another part that feeds it on into the combine where it is shucked and taken off of the cob and separated from all of that and stored in a bin on the combine. When the combine is full then you drive it up to a truck and put the auger out and empty the grain into a truck.

In the second and third picture you can see the rows of corn before the combine picks it. The third picture shows a combine unloading into an auger wagon that's pulled by a tractor. When you have an auger wagon the combine doesn't have to stop and unload. It can keep going and the auger wagon does the unloading for it.
