PROBLEM TO BE SOLVED: To provide a harvester in which only the main harvest part of crops is steadily separated, even when a standing crop adopts a falling position, and the efficiency of harvest work can be improved by suppressing the occurrence of dust.SOLUTION: A harvester includes a harvest unit in front of a self-propelling body capable of self-propelling. The harvest unit is provided with a pre-processing unit for preprocessing such as previous change of a standing crop into a posture so as to facilitate a following post-processing unit to perform post-processing, and the post-processing unit for performing post processing such as separation of the main harvest part of crops pre-processed in the pre-processing unit. The pre-processing unit is mounted in the post-processing unit, and can be freely lifted and lowered between a lowered position capable of pre-processing in proximity to a field surface, and a lifted position separated from the field surface and incapable of pre-processing.COPYRIGHT: (C)2015,JPO&INPIT【課題】立毛の作物が倒伏姿勢等を採っている場合でも、作物の要収穫部のみを堅実に分離するとともに塵の発生を抑制して、収穫作業能率を向上させることができる収穫機を提供すること。【解決手段】自走可能とした自走本体の前方に収穫部を備えた収穫機であって、収穫部には、立毛の作物を前もって後続の後処理部が後処理し易い姿勢に変更する等の前処理をする前処理部と、前処理部で前処理された作物の要収穫部を分離する等の後処理をする後処理部を設け、前処理部は、後処理部に取り付けるとともに、圃場面に近接して前処理可能な下降位置と、圃場面から離隔して前処理不可能な上昇位置との間で昇降自在となした。【選択図】図1
