PROBLEM TO BE SOLVED: To provide a combine harvester with which when grain stored in a grain tank is unloaded to the outside, the unloaded weight is measured. SOLUTION: After an automatic rotation switch is made ON (S11:YES), whether or not an auger rest switch is made OFF is judged (S12) . When the auger rest switch is made OFF is judged (S12:YES), weight of the grain tank being a measured value beforeΔt seconds is retained as weight before operation (S13). Then, after the unloading operation is completed, an unloading auger is rotated and moved to a housing position and whether or not the auger rest switch is made ON is judged. When the auger rest switch is made ON is judged, the weight of the grain tank after passage of a fixed timeΔt is retained as weight after the operation and difference between the weight before the operation and the weight after the operation is obtained to calculate the unloaded weight.
