To provide a combine harvester by which the operability of grain-unloading operation by an unloading auger by using a remote operation device can be improved by shortening the operation time of the remote operation device.

The combine harvester 1 includes the unloading auger 32 for unloading grains in a grain tank 17 to the exterior, and capable of being lifted or lowered, and turned, a lifting or lowering actuator 37 for lifting or lowering the unloading auger 32, a turning actuator 35 for turning the unloading auger 32, a controller 60 for controlling the drive of each of the actuators 35 and 37, and the remote operation device 80 having operation means for lifting or lowering the unloading auger 32, and the operation means for turning by remote operating the controller 60 by using wireless communication. When each operation means is operated simultaneously, the controller 60 turns the unloading auger 32 while lifting or lowering the unloading auger by simultaneously controlling each of the actuators 35 and 37 so as to correspond to the operation.
