To provide a paddy field implement capable of changing and setting a supply amount of an agricultural material to a field surface according to states of a paddy field and the agricultural material without risk of damage of a work device, without a special device for regulation on the work device.SOLUTION: A paddy field implement comprises: a first speed changer 24 to which motive force of a prime mover part is transmitted; 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; a branch part for branching the motive force of the first speed changer 24 to a travel transmission system and a work transmission system; wheels for travel to which motive force of the travel transmission system is transmitted; and a second speed changer 45 for changing speed of the motive force of the work transmission system and then transmitting the same to the work device. The second speed changer 45 has a checking mechanism K for allowing normal rotation motive force out of the motive force of the work transmission system to be transmitted to the work device and checking transmission of reverse rotation motive force to the work device.SELECTED DRAWING: Figure 5

    【課題】作業装置に特別な規制用の装置を備えなくても、作業装置の損傷のおそれがない状態で、水田や農用資材の状態等に応じて、圃場面に対する農用資材の供給量を変更設定できる水田作業機を提供する。【解決手段】原動部の動力が伝達される第一変速装置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、第一変速装置24の動力を走行伝動系及び作業伝動系に分岐する分岐部と、走行伝動系の動力が伝達される走行用の車輪と、作業伝動系の動力を変速して作業装置に伝達する第二変速装置45とが備えられ、第二変速装置45に、作業伝動系の動力のうち正転動力が作業装置に伝達されることを許容し、且つ、逆転動力が作業装置に伝達することを牽制する牽制機構Kが備えられている。【選択図】図5
