PROBLEM TO BE SOLVED: To provide a riding type transplanter for planting seedlings and simultaneously supplying an agrochemical materials to a paddy surface, wherein a deaerating work and works for eliminating the bridge phenomenon of each portion can suitably be performed, before a planting work is started and after an agricultural supply material is charged into an empty storage portion.SOLUTION: This riding type transplanter has a planting transmission system for transmitting power to a seedling-planting device 5 and an agrochemical material transmission system for transmitting power to delivery portions 80a to 80h, 81a to 81d, which are disposed in parallel. The power is transmitted to the seedling-planting device 5 via the planting transmission system, and the power is transmitted to the delivery portions 80a to 80h, 81a to 81d via the agrochemical supply material transmission system. A transmission-disconnection mechanism 50 for freely transmitting or disconnecting power is provided at a planting transmission system portion on the upstream side of the seedling-planting device 5.COPYRIGHT: (C)2008,JPO&INPIT【課題】 苗の植え付けを行いながら農用供給体を田面に供給するように構成された乗用型田植機において、植付作業の開始前に空の貯留部に農用供給体を入れた後に、空気を抜く作業や各部のブリッジ現象を消失させる作業が、適切に行えるように構成する。【解決手段】 苗植付装置5に動力を伝達する植付伝動系と、繰り出し部80a~80h,81a~81dに動力を伝達する農用供給体伝動系とを並列的に配置する。植付伝動系を介して苗植付装置5に動力を伝達し、農用供給体伝動系を介して繰り出し部80a~80h,81a~81dに動力を伝達するように構成する。苗植付装置5よりも上手側の植付伝動系の部分に、動力を伝動及び伝動遮断自在な伝動遮断機構50を備える。【選択図】 図5
