PROBLEM TO BE SOLVED: To provide a pick-up device which softens the impacts of pick-up actions to prevent a problem that the reaping failure of lodged straws, the shedding or breakage of standing straws and the like are caused with a portion of the pick-up apparatus, when crops existing in both a lodged state and a standing state are simultaneously reaped with a multi-row reaping combine harvester at the same pick-up speed and a problem that tines pass through the ears of short straw crops to loss the grains, when soybeans, buckwheat or the like are harvested. SOLUTION: This combine harvester in which a multi-row reaping portion is mounted on the front portion of the machine frame is characterized by driving a tine-having chain 3 with an electric motor 2 disposed in each pick-up case 1 in a state capable of being adjusted to a pick-up speed V1 or V2 suitable for lodged crops, soybeans, buckwheat, or the like, detecting lodged crop resistance values acting on the pick-up cases 1 by sensors S1 to S4 to change the speeds for reaping rows, respectively, disposing an adjustment mechanism in which a variable switch 8 for steplessly changing the whole pick-up speed, and forming the pick-up cases 1 so that the pick-up cases 1 can be inclined in a truncated chevron shape in plan view.
