PROBLEM TO BE SOLVED: To solve the problem that when braking action is constantly worked in a turn-controlling motor and an electromagnetic brake of grain-discharging auger equipment, the vibration of a chassis and/or reaction force in steering burden(s) the shaft of the motor, etc., with excessive torque to damage it. SOLUTION: The grain-discharging auger equipment 3 of a combine harvester 1 is equipped with both of the turn-controlling motor 4 and the electromagnetic brake 5 which enable turn control and braking action in being halted. The brake 5 is constructed by being connected to a controller 6 in such a way that the braking action is interrupted when the running speed of the combine harvester 1 exceeds the preset value of the speed or a controlling device 7 is operated; besides, interrupted time for the above braking action can be preset.
