However, according to the present invention, in a combine provided with a weight sensor for measuring the grain weight of the grain tank, a lock member for locking the support of the grain tank and stopping the measurement of the weight sensor is provided, and the lock by the lock member is released. Grain weight is measured, for example, when the direction of grain weight is measured, such as when the direction is not changed in the field headland or immediately before the grain is discharged from the grain tank, and the grain tank support structure is simplified. And reduction of grain weight measurement error can be easily performed.
[0006]
Further, as in claim 2, the grain tank is provided swingably around the bottom conveyor for discharging the grain inside the grain tank, and a weight sensor or a lock member is installed on the side of the grain tank.
