PROBLEM TO BE SOLVED: To solve the problems of a conventional riding type seedling transplanter whose machine frame is not small and compact but is large and which has low seedling-supplying work efficiency and low seedling transplantation work efficiency.SOLUTION: There is provided the seedling transplanter wherein a planting portion 1b having a seedling-supplying device 4 and a seedling-planting device 5 is disposed in the rear portion of a travel portion 1a having front wheels 3 and rear wheels 2. The transplanter is characterized by disposing a seedling-putting table 90 disposed in a state capable of being moved in the lateral direction of the seedling-supplying device 4 above the rear portion of the travel portion 1a in a state that the front portion of the seedling-putting table 90 is high and the rear portion is low, disposing a seeding-taking device 43 for individually taking out seedlings from a seedling tray T put on the seedling-putting table 90 and then individually supplying the taken seedlings into the seedling-planting tool 42 of the seedling-planting device 5 and the seedling-planting device 5, behind the frame of the seedling-supplying device 4, and disposing a seat 212 in which a worker sits toward the planting portion 1b, in the front portion of the travel portion 1a.COPYRIGHT: (C)2010,JPO&INPIT【課題】従来の乗用型の苗移植機は、その機体構成が大型となり、小型でコンパクトな構成ではなく、また、苗供給作業効率・苗移植作業効率に課題があった。【解決手段】前輪3と後輪2を有する走行部1aの後部に苗供給装置4及び苗植付装置5を有する植付部1bを設けた苗移植機において、該苗供給装置4の左右方向移動自在に設けた苗載台90を走行部1aの後部上方に前部が高く後部が低い状態で配置し、苗載台90に載置した苗トレイTから苗を一つずつ取出して苗植付装置5の苗植付具42に供給する苗取装置43と苗植付装置5を苗供給装置4の機体後方に配置すると共に、走行部1aの前部に作業者が植付部1bの方向を向いて着座する座席212を設けた苗移植機。【選択図】図1
