Method and apparatus for harvesting crops

摘要

A method and system of harvesting crops involves cutting and threshing the crop, separating graff from straw, and returning the straw to the field. This is carried out in a harvesting unit of the pull type having a graff storage tank. The collected graff is moved to a stationary cleaning mill in a different location by means of a suitable vehicle such as a truck. Storage of the graff prior to cleaning is avoided and the cleaning mill, and the harvesting unit and vehicle.
