PROBLEM TO BE SOLVED: To provide a farm field work machine which allows a work material to be replenished easily and can further simplify control of a machine body which can travel automatically.SOLUTION: A farm field work machine is provided with a travelling vehicle body (1) which can travel and a position information acquisition device (5) for acquiring position information indicating a position of its own vehicle, and includes a control device (3) for causing the travelling vehicle body (1) to travel automatically on the basis of the position information acquired by the position information acquisition device (5). The farm field work machine is provided with a scattering device (X) for scattering a material to be scattered in a farm field (100) while following a route in which the travelling vehicle body (1) has travelled. The scattering device (X) scatters the material to be scattered within the right-left width with respect to a travelling direction of the travelling vehicle body (1).SELECTED DRAWING: Figure 9COPYRIGHT: (C)2020,JPO&INPIT【課題】作業資材の補給を容易に行うと共に、自動走行可能な機体の制御をより簡略化できる圃場作業機を提供することを目的とする。【解決手段】走行可能な走行車体（１）と、自車両の位置を示す位置情報を取得する位置情報取得装置（５）とを備え、前記位置情報取得装置（５）が取得した位置情報に基づいて前記走行車体（１）を自動走行させる制御装置（３）を備えた圃場作業機において、前記走行車体（１）が走行した経路を追従すると共に、前記圃場（１００）に散布対象物を散布する散布装置（Ｘ）を設け、散布装置（Ｘ）は、走行車体（１）の進行方向に対して左右幅内に散布対象物を散布することを特徴とする。【選択図】図９
