PROBLEM TO BE SOLVED: To provide a riding type seedling transplanter having improved operability and a simple structure, because a conventional seedling transplanter for a sweet potato seedling or the like can transplant the vine-shaped seedling so that the vine-shaped part may be buried in the soil so as to be long in the front and rear direction, and the transplanting operation of the vine-shaped seedling can be carried out by a machine to improve the operability compared to manual operation, an operator must carry out the seedling-transplanting operation while walking because the seedling transplanter is the walking type one, and further improvement of the operability is required.SOLUTION: The riding type seedling transplanter obtained by installing a seedling-conveying part 5 and a seedling-transplanting body 6 for taking out the seedlings conveyed by the seedling-conveying part 5 and transplanting the seedlings on the field, in a running machine body 4 traveling by right and left running devices 7 includes a seat 120 on which the operator sits, and which is installed in right or left one side of the machine body so as to face the seedling-conveying part 5, and an assistant running device 123L for supporting the seat 120, at least installed in the rear-side position of one running device 7 in the right and left running devices 7.COPYRIGHT: (C)2012,JPO&INPIT【課題】従来の甘薯苗等の苗移植機は、蔓状の苗を蔓の部分が土壌内で前後に長く埋められるように植付けることができ、蔓状の苗の移植作業が機械で行え、手植え作業に比して作業性が向上した。然しながら、該苗移植機は歩行型苗移植機であって、作業者は圃場を歩きながら苗移植作業をしなくてはならず、更に作業性を向上する必要がある。そこで、作業性が向上する簡潔な構成の乗用型苗移植機を得ることを課題とする。【解決手段】左右走行装置7にて進行する走行機体4に苗搬送部5と該苗搬送部5にて搬送された苗を取出して圃場に植付ける苗植付け体6を設けた乗用型苗移植機において、該苗搬送部5に対向して作業者が着座する座席120を機体の左右一側に設けると共に、該座席120を支持する補助走行装置123Lを左右走行装置7の少なくとも何れか一方の走行装置7の後方位置に設けた乗用型苗移植機。【選択図】図1
