PROBLEM TO BE SOLVED: To provide a field work machine that facilitates assembling a drive unit for driving a supply device.SOLUTION: A field work machine includes: a supply device for supplying an agricultural material to a field by the drive of a drive shaft； drive units 37, 40 for driving the drive shaft； and a mounting plate 65 provided between the supply device and the drive units 37, 40, and connecting and fixing the supply device with the drive units 37, 40. The mounting plate 65 and the supply device are connected by a first bolt Bo1. The mounting plate 65 is formed of first bolt insertion holes 66a, 66b for allowing the first bolt Bo1 to be inserted. The first bolt insertion holes 66a, 66b are formed in a diameter larger than a bolt diameter of the first bolt Bo1 so that a position can be adjusted in the direction being vertical or substantially vertical to an axial direction of the drive shaft.SELECTED DRAWING: Figure 8COPYRIGHT: (C)2020,JPO&INPIT【課題】供給装置を駆動するための駆動ユニットの組み付けが容易な圃場作業機を提供する。【解決手段】駆動軸の駆動によって圃場に農用資材を供給する供給装置と、駆動軸を駆動する駆動ユニット３７，４０と、供給装置と駆動ユニット３７，４０との間に設けられ、供給装置と駆動ユニット３７，４０とを連結固定する取付板６５と、が備えられ、取付板６５と供給装置とは第一ボルトＢｏ１によって連結され、取付板６５に、第一ボルトＢｏ１の挿通を許容する第一ボルト挿通孔６６ａ，６６ｂが形成され、第一ボルト挿通孔６６ａ，６６ｂは、駆動軸の軸心方向と垂直又は略垂直な方向に位置調整可能なように、第一ボルトＢｏ１のボルト径よりも大きな直径に形成されている。【選択図】図８
