PROBLEM TO BE SOLVED: To provide a constitution capable of surely lowering a discharge auger to a prescribed position in an automatic storage control of the discharge auger of a combine.SOLUTION: A controller 11 executes an automatic storage control including: lowering control (step S103) for controlling a solenoid valve 50 to lower a discharge auger 17 toward an auger rest 41 and lowering stop control (step S109) for stopping the lowering control if detection result of a lifting/lowering position detection unit 53 continues unchanged for a predetermined storage determination time during executing the lowering control (determination of step S106 and S107).
