Patent 10278329 was granted and assigned to Kubota Corporation on May, 2019 by the United States Patent and Trademark Office.
A grain management system includes a combine and a management server. The combine includes a grain measurer for outputting a measured value related to a component of harvested grains supplied to a grain tank, and a data transmitter for transmitting the measured value and field identification information for specifying the field to the management server via a communication line. The management server includes a receiver for receiving the field identification information and the measured value from the combine, a table manager for determining a measured value-grain component value table for deriving a grain component value using the measured value based on the field identification information, and a grain component value computer for obtaining the grain component value based on the measured value, using the measured value-grain component value table that is determined by the table manager.
