To provide a paddy field implement capable of properly setting a supply amount of an agricultural material.SOLUTION: A paddy field implement comprises: a speed changer 24 to which motive force of a prime mover part is transmitted； and a work device for supplying an agricultural material to a field surface at a supply amount which has been set in advance along a travel direction of the machine body. The motive force of the speed changer 24 is branched in a parallel state to a travel transmission system and a work transmission system, the motive force of the travel transmission system is transmitted to wheels for travel, the motive force of the work transmission system is transmitted to the work device through a stepless speed changer 45, and there are provided speed reduction mechanisms 50, 51 on a downstream side of an output part 45b of the stepless speed changer 45.SELECTED DRAWING: Figure 4【課題】水田作業機において、農用資材の供給量を適切に設定できるようにする。【解決手段】原動部の動力が伝達される変速装置２４と、機体の走行方向に沿って事前に設定された供給量で、農用資材を圃場面に供給する作業装置とが備えられ、変速装置２４の動力が走行伝動系及び作業伝動系に並列的に分岐されて、走行伝動系の動力が走行用の車輪に伝達され、作業伝動系の動力が無段変速装置４５を通って作業装置に伝達され、無段変速装置４５の出力部４５ｂよりも下流に減速機構５０，５１が設けられている。【選択図】図４
