There is a technology that collects the grain (paddy) of the grain and transfers the grain in the grain tank to a truck bed etc. to be transported to the country elevator. The grain capacity inside the grain tank is detected in multiple stages, and the grain removal time and empty Although the state was detected, the weight of the harvested grain is unknown until the grain is carried into the country elevator and weighed. for that reason,
By performing continuous harvesting in multiple fields, it is necessary to calculate the weight of the grains harvested in each field based on the volume of grains harvested in each field and the total weight of grains measured by the country elevator. In addition, there is a problem that a calculation error of a grain weight for each field tends to be large due to a difference in a water content or a specific gravity of the grain which is different between the fields. Therefore, it is necessary to weigh the grains harvested in each field with a country elevator or the like, check the grain weight in each field, and use it as a reference for soil improvement or fertilization and water management in the field. There is a problem that it is not easy to improve efficiency and optimize field management.

Obtained readily ascertained harvesting grain weight also each field when performing continuous harvesting work with multiple fields were,
Soil improvement or fertilization and water management can be appropriately performed for each field with reference to the weight of harvested grains in each field, so that it is possible to easily improve the efficiency of harvesting work and optimize the field management.

[0004] In addition, the weight of the grain of the grain tank in operation is calculated by detecting the operating oil pressure of a rolling cylinder for controlling the horizontal inclination of the machine by a weight sensor, and the machine load supported by the rolling cylinder is controlled. Since the weight of the harvested kernel is calculated based on the change, the structure for detecting the weight of the harvested kernel can be simplified, the manufacturing cost can be reduced, and the accuracy of detecting the weight of the harvested kernel can be easily improved.
