A combine harvester, or "combine," has streamlined the harvest process, enabling farmers to bring in more crops faster. As a combine works its way through a farm field, it can pick the crops and separate the grain from the chaff within the inner area of the combine. Farmers use combines to harvest corn, wheat, oats, rye, soybeans, barley and flax fields.
Place the appropriate header onto the front of the combine for the crop you will harvest. The header gathers the crops into the combine harvester as it moves through the field.
Position the combine at the edge of a field at the beginning of the rows of crops. Move the combine through the field, raising and lowering the header to reap the crops. The mechanisms within the harvester will move the crops through, cutting them, moving them up a conveyor belt and then threshing them to separate the grain from the chaff. The grain falls into a tank, and the chaff will continue to go through the machine until the combine harvester eventually spews it back out into the farm field.
Bring a tractor pulling a trailer alongside the combine harvester when the grain tank fills to capacity. Route the grain through an elevator and expel it from the unloader into the trailer.
Continue moving the combine through the field to harvest the grain. Every time the grain tank fills, empty it into a trailer.
