PROBLEM TO BE SOLVED: To provide a seedling transplanter which can select the operation or non-operation of a rotor 27 independently from the operation of a lever 81 for adjusting the upper or lower rotor position of the rotor, and can achieve the selection of the operation or non-operation of the rotor 27 and the height adjustment of the rotor 27 in a simple structure.SOLUTION: A rotor receiving lever 84 for lifting or lowering the liftably disposed rotor 27 at a lifted non-working position or a lowered working position is disposed in a seedling-planting portion 4 liftably disposed in the rear portion of the travel vehicle body 2 of the seedling transplanter, and a flexible space (S1) is disposed in an operation system of an adjustment lever 81 for lifting or lowering the rotor 27 by the operation of the rotor upper or lower position adjustment lever 81 to change and adjust a height at the working position the rotor 27 carried out with the lever 84.COPYRIGHT: (C)2007,JPO&INPIT【課題】ロータ27の作動と非作動の選択をロータ上下位置調節レバー81の操作から独立して行うことができ、しかもこれらロータ27の作動と非作動の選択とロータ27の高さ調節を簡単な構成で達成できる苗移植機を提供すること。【解決手段】苗移植機の走行車体2の後部に昇降自在に設けた苗植付部4に対して昇降自在に設けたロータ27を上昇した非作業位置と下降した作業位置とに昇降するためにロータ収納用レバー84を設け、該レバー84によって行われたロータ27の作業位置での高さを変更調節するためにロータ上下位置調節レバー81の操作でロータ27を昇降させるために該調節レバー81の操作系統に設けた融通空間(S1)とを設けた。【選択図】図3
