AGRICULTURAL WORKING MACHINE

To prevent soil which is scooped up rearward by discs from arriving at an upper part of a cultivation working part, in an agricultural working machine in which a plurality of the discs are arranged ahead of a working rotor.SOLUTION: An agricultural working machine comprises; a working rotor including a plurality of cultivation claws; a cover member arranged above the working rotor so as to progress along the working rotor; a disc unit arranged ahead of the working rotor, and including a plurality of discs which are rotatably supported; and an auxiliary cover which is arranged ahead of the cover member in a plane view. At least a part of the auxiliary cover is substantially vertical with respect to a farm field in a side face view, located at a rear part rather than a first tangent contacting with rotation trajectories of the discs between the discs and the working rotor, also passes a front end of the cover member, and is located in a region above a second tangent contacting with the rotation trajectories of the discs between the discs and the working rotor.SELECTED DRAWING: Figure 3 【課題】作業ロータの前方に複数のディスクを配置した農作業機において、ディスクによって後方に跳ね上げられた土が耕耘作業部の上方に到達してしまうことを抑制すること。【解決手段】農作業機は、複数の耕耘爪を含む作業ロータと、前記作業ロータの上方に、当該作業ロータに沿うように配置されたカバー部材と、前記作業ロータの前方に配置され、それぞれ回転可能に支持された複数のディスクを含むディスクユニットと、平面視において、前記カバー部材の前方に配置された補助カバーと、を備え、前記補助カバーの少なくとも一部は、側面視において、圃場に対して略垂直であって前記ディスクと前記作業ロータとの間において前記ディスクの回転軌跡に接する第１接線よりも後方であって、前記カバー部材の前端を通り前記ディスクと前記作業ロータとの間において前記ディスクの回転軌跡に接する第２接線よりも上方の領域に位置する。【選択図】図３
