PROBLEM TO BE SOLVED: To reduce drive power energy consumption in a hybrid combine harvester carrying out driving of a threshing cylinder by an electric motor.SOLUTION: When a reaper (4) is raised, a combine harvester stops driving of a cereal culm- raking and transferring device (23) provided to the reaper (4), and stops driving of a threshing cylinder (5b) by an electric motor (12) or to reduce a driving velocity of the threshing cylinder (5b) by the electric motor (12). The combine harvester is constituted so that a cereal culm sensor (4d) for detecting the cereal culms is provided to the cereal culm-raking and transferring device (23), and when the cereal culms are detected by the cereal culm sensor (4d) during raising of the reaper (4), the drive velocity of the threshing cylinder (5b) is reduced while the cereal culm-raking and transferring device (23) is driven, and when the cereal culms are not detected by the cereal culm sensor (4d), the driving of the cereal culm- raking and transferring device (23) and the threshing cylinder (5b) is stopped or the driving velocity of the threshing cylinder (5b) by the electric motor (12) is reduced. |
