PROBLEM TO BE SOLVED: To provide an agricultural work machine having a function reducing influence by a travel mark of a tractor efficiently, the agricultural work machine performing agricultural work while mounted on the tractor.SOLUTION: An agricultural work machine 100 performing agricultural work while mounted on a tractor includes a soil gathering device 3 guiding soil into a groove of a travel mark of a tractor. The soil gathering device 3 includes: a base plate 32 fixed at a predetermined angle with respect to a travel direction; and a soil adhesion prevention member 41 attached on a surface of the base plate 32. The soil adhesion prevention member 41 is formed by a material more hardly allowing soil to adhere thereon than the base plate 32 and soil is guided by the soil adhesion prevention member 41.SELECTED DRAWING: Figure 1【課題】トラクタに装着して農作業を行う農作業機においてトラクタの走行跡による影響をより効率的に軽減する機能を有する農作業機を提供することを目的とする。【解決手段】トラクタに装着して農作業を行う農作業機100において、トラクタの走行跡の溝に土を案内する土寄せ装置3を備え、土寄せ装置3は、走行方向に対して一定角度で固定されるベース板32と、ベース板32の表面に取り付ける土付着防止部材41とを備え、土付着防止部材41は、ベース板32よりも土が付着しにくい材質により形成して、土を土付着防止部材41により案内する。【選択図】図1
