Grain Combines

The combine harvester[1] or simply, combine, is a machine that combines the tasks of harvesting, threshing, and cleaning grain crops.

The combine:

1. Cuts the entire stalk

2. Separates the grain from the stalk

3. Discards the debris out the back of the machine

4. Stores the grain in the top.

• The dried leaves and stems that the combine leaves behind are baled for feed and bedding for livestock.

• The head of the combine can be changed to a grain table[2] for harvesting small grains such as wheat and soybeans.

• A corn header[3] is used for corn.
