PROBLEM TO BE SOLVED: To reap lodged crops favorably with few non-reaped crops while avoiding damage of a divider due to contact with a ground surface.SOLUTION: The harvester includes: a reaping processing part reaping crops and thereafter conveying the crops laterally toward a center part in a machine body lateral width direction to be joined and a feeder feeding the crops laterally conveyed in the reaping processing part toward a machine body rear part. The reaping processing part includes a divider 13 which is arranged in a machine body front part side of each of a pair of side walls 20 positioned on both side edges in the machine body lateral width direction and which divides crops to be reaped from crops not to be reaped. The divider 13 includes: a divider body 13A positioned in an upper part side and a bottom part division body 13B attached detachably on a lower side of the divider body 13A.SELECTED DRAWING: Figure 3COPYRIGHT: (C)2017,JPO&INPIT【課題】地面との接触によるデバイダの損傷を回避しながら、倒伏している作物を刈残しを少ない状態で良好に刈り取ることができるようにする。【解決手段】作物を刈り取ったのち機体横幅方向中間部に向けて横送りして合流させる刈取処理部と、その刈取処理部にて横送りされた作物を機体後方に向けて搬送するフィーダとが備えられ、刈取処理部に、機体横幅方向両側端部に位置する一対の側壁部20夫々の機体前部側に、刈取対象となる作物と非刈取対象の作物とを分草するデバイダ13が備えられ、デバイダ13は、上部側に位置するデバイダ本体13Aと、デバイダ本体13Aの下側に着脱可能に取り付けられる底部分割体13Bとを備えている。【選択図】図3
