PROBLEM TO BE SOLVED: To solve the problem that: when an unloading of grains is started again from such a condition that the grains are left in an unloading auger, the unloading port are clogged with the grains.;SOLUTION: A combine harvester 1 is provided, including: a grain tank 4 where grains are reserved; an unloading auger 5 functioning to unload the grains in the tank 4 out of the machine; an unloading clutch for turning on/off the mechanical power of the unloading auger 5; a shutter 14 functioning to open/close the unloading port 13 of the unloading auger; and a controller 20 functioning to control the unloading clutch and the shutter 14 correspondingly to the operation of a grain-unloading switch 32. In the combine harvester, the controller 20 works as follows: when the turning-ON control of the unloading clutch and the releasing control of the shutter 14 are to be conducted in response to the unloading-starting operation of the grain-unloading switch 32, the timing of starting the turning-ON action of the unloading clutch is delayed relative to the timing of starting the releasing action of the shutter 14.;COPYRIGHT: (C)2011,JPO&INPIT
