摘要

A combine provided with a grain tank in which grains obtained by threshing are supplied and stored; a flow rate sensor 50 which is provided in the grain tank and measures a flow rate of the grains being supplied; a yield sensor 10 which is provided under the grain tank and outputs an output value based on the weight of the grain tank; and a control unit 22 which calculates a current yield of the grains stored in the grain tank on the basis of the flow rate and the output value.
