Corn Headers are created in a series of 6 rows, 8 rows, 12 rows, 16 rows, 24 rows and so forth.
The number of harvested rows is selected based on the capacity and engine power requirement of the combine harvesters.
Corn headers have three main types, depending on their main functions:
1. Corn headers, used for gathering the ears only, while the stalks are cut down.
2. Chopping corn headers, used for harvesting the ears and chopping the stalks. The stalk fragments are then spread on the farm.
3. Integral corn headers, used for collecting the ears, chopping and collecting the stalk fragments. The fragments are to be left on the surface as a continuous swath, or to be stored in a trailer that moves in parallel with the combine harvester.
