PROBLEM TO BE SOLVED: To constitute a paddy field working machine which supplies particulate matters to a field face so that, when the particulate matters are supplied to the field face in a state of being dot-scattered, the particulate matters are not supplied to the field face in a zigzag state when operating and stopping a part of a payout part.SOLUTION: Occlusal parts 79a, 79b are arranged at one of upper-side and lower-side transmission bodies 73, 74, a part 80 to be occluded is arranged at the other of the upper-side and lower-side transmission bodies 73, 74, the occlusal parts 79a, 79b and the part 80 to be occluded are occluded to or separated from each other, and thus a payout rotating body 99 is rotated or stopped. The number of combinations of the occlusal parts 79a, 79b and the part 80 to be occluded is set as one, or set as an individual number which is the same as an individual number of recesses 99a to 99d of the payout rotating body 99, or set as an individual number which is the same as a divisor of the individual number of the recesses 99a to 99d of the payout rotating body 99.【課題】粉粒体を田面に供給する水田作業機において、粉粒体を点播状態で田面に供給する場合、一部の繰り出し部を作動及び停止させた際に粉粒体が千鳥状に田面に供給されないように構成する。【解決手段】上手側又は下手側伝動体７３，７４の一方に咬合部７９ａ，７９ｂを備え、上手側又は下手側伝動体７３，７４の他方に被咬合部８０を備えて、咬合部７９ａ，７９ｂと被咬合部８０とを咬合及び離間させることにより、繰り出し回転体９９が回転及び停止するように構成する。咬合部７９ａ，７９ｂと被咬合部８０との組み合わせの数を、１個、又は繰り出し回転体９９の凹部９９ａ～９９ｄの個数と同じ個数、又は繰り出し回転体９９の凹部９９ａ～９９ｄの個数の約数と同じ個数に設定する。【選択図】図２７
