PROBLEM TO BE SOLVED: To achieve improvement of operation accuracy while simplifying a configuration of a paddy field working machine.SOLUTION: A paddy field working machine comprises: a plurality of feeding mechanisms 15 arranged at regular intervals in a lateral direction for feeding a plurality of seedlings or seed rice to a farm field a plurality of main floats 16 arranged in the lateral direction for leveling a feeding place of the feeding mechanisms 15 on a field mud surface prior to the feeding operation of the feeding mechanisms 15 and front floats 17 for leveling a mud surface portion located between at least two adjacent main floats 16 prior to each main float 16. Each main float 16 is configured to individually swing in a vertical direction with each rear side spindle 27 in the lateral direction as a fulcrum, and also the front float 17 is configured to swing vertically with a front side spindle 39 in the lateral direction, which is located on the machine body front side of the rear side spindle 27, as a fulcrum. Each main float 16 and front float 17 are arranged so as to have a predetermined distance between the rear side of the front float 17 and the front side of the main float 16 located behind the front float.COPYRIGHT: (C)2015,JPO&INPIT【課題】水田作業機の構成の簡素化を図りながら作業精度の向上を図れるようにする。【解決手段】複数条分の苗又は種籾を圃場に供給するように左右方向に一定間隔で配置した複数の供給機構15と、供給機構15の供給作動に先行して圃場泥面における供給機構15の供給箇所を整地するように左右方向に並べて配置した複数の主フロート16と、各主フロート16に先行して少なくとも隣接する2つの主フロート16の間に位置する泥面部分を整地する前フロート17とを備え、各主フロート16は、それぞれの左右向きの後側支軸27を支点にして個別に上下揺動するように構成し、かつ、前フロート17は、後側支軸27よりも機体前側に位置する左右向きの前側支軸39を支点にして上下揺動するように構成して、各主フロート16と前フロート17とを、前フロート17の後部側と、その後に位置する主フロート16の前部側との間に所定間隔を有するように配備した。【選択図】図4
