Abstract: A method of harvesting grain involves placing a cutting and harvesting head on the front of a prime mover, moving the prime mover and the head through a field of mature grain plants with grain thereon. The grain bearing plants are then cut with the head, and then moved to a grain separating station on the head. The grain is then separated from the plants within the head, captured, and then moved to a grain reservoir on the prime mover. The severed plants are then deposited into the field after the grain is separated therefrom. A combine or prime mover has a grain harvesting head on the forward end thereof. A cutter bar or the like is on the head to cut grain bearing field plants. A conveyor moves the cut plants to threshing elements on the head for separating grain from the severed plants. A grain conveyor on the head moves the grain to a grain reservoir on the combine. An exit port is on the head for depositing all of the plants in the head on the field from which the plants were cut.
