PROBLEM TO BE SOLVED: To maintain the puddling performance, that is, the ground levelling performance which might otherwise be caused to non-constant, because the distance between a first land-leveling member and a second land-leveling member is not made inconstant according to the rotary angle of the second land-leveling member.SOLUTION: An agricultural implement comprises: a first land-leveling member and a second land-leveling member connected rotatably to the first land-leveling member. The second land-leveling member includes a body part, and an extended curvature part positioned on the side of the first land-leveling member. The second land-leveling member is made turnable on the curvature center of the extended curvature part.SELECTED DRAWING: Figure 4COPYRIGHT: (C)2018,JPO&INPIT【課題】第2整地部材の回動角度に応じて、第1整地部材と第2整地部材との距離が一定でないことによって第1整地部材と第2整地部材との間隙を流れる水量が変化し、第1整地部材と第2整地部材との間隙を流れる水量が変化することで代掻きの仕上がり性能、すなわち土壌整地能力が一定でなくなってしまう。【解決手段】第1整地部材と、第1整地部材に対して回動可能に接続された第2整地部材とを有し、第2整地部材は、本体部と第1整地部材側に位置する湾曲した延長湾曲部とを有し、延長湾曲部の曲率中心を回転中心として第2整地部材が回動可能である、農作業機。【選択図】図4
