The present invention allows the weight of the grain tank to work stably when the weight of the grain tank is detected using a load cell so as to avoid the reduction in the detection accuracy of the grain weight. The support leg part 80 provided and the support leg part 80 are flat in each opposing location of the guide member 70 provided in the base frame 1 so that the support leg part 80 may be guided to the upper side of the hydraulic pressure surface 63A of the load cell 60. The portions 71 and 83 are provided so that the weight of the grain tank 5 in the working posture position in the state where the support legs 80 and the flat portions 71 and 83 of the guide member 70 are in surface contact with each other. It is configured to act on the load cell 60. In addition, the present invention is to provide a combine that was able to improve the degree of freedom in the design by making the arrangement position of the water quantity sensor relatively freely when detecting the weight of the grain tank, the grain tank for grain storage ( 5), the water quantity sensor 60 arranged below the grain tank 5, the main frame 12 arrange positioned along the gas front-back direction, and the pedestal bracket 13 provided in the main frame 12 continuously The quantity sensor 60 is mounted over the main frame 12 and the pedestal bracket 13. In addition, the present invention provides an inclination sensor 3066 that detects the inclination of the traveling gas so that the detection accuracy of the grain weight can be avoided from being reduced due to the inclination of the gas when detecting the grain tank weight using a load cell. ) And a load cell 3060 for detecting the weight of the grain tank 3005, and the output control means 3106 includes a quantity measuring means 3104 when the detected value of the inclination by the inclination sensor 3066 is within an allowable range. When the control command based on the calculation result in is output to the output target device 3034,
