PROBLEM TO BE SOLVED: To provide a ground-leveling float for a paddy field working machine having a width corresponding to an entire row and allowing easy and satisfactory planting while suppressing an adverse effect of a mud press on neighboring rows.SOLUTION: A ground-leveling float for a paddy field working machine includes: a ground-leveling body 20 having a width corresponding to an entire row and mud releasing paths 28, 29 for guiding a mud flow from a front side to a back side of the ground-leveling body 20. The mud releasing paths 28, 29 can be switched between a communicating state in which the mud flow can be guided therethrough and a restricting state in which the mud flow is blocked therein.COPYRIGHT: (C)2014,JPO&INPIT【課題】全条に相当する横幅を有しながら、泥押しによる隣接条への悪影響を抑制して、植付が良好に行われ易い水田作業機の整地フロートを提供する。【解決手段】全条に相当する横幅を有した整地体20と、その整地体20の前方側から後方側へ泥流を誘導する泥逃がし通路28,29とが備えられ、泥逃がし通路28,29は、泥逃がし通路28,29内での泥流の誘導が可能な連通状態と、泥逃がし通路28,29内における泥流の流れを阻害する制限状態とに切換操作可能に構成されている。【選択図】図4
