PROBLEM TO BE SOLVED: To provide a riding transplanter capable of rapidly performing turning operation of the machine body during planting operation.SOLUTION: The riding transplanter is equipped with: a first operation tool 22 for performing lifting and lowering operation of a planting implement 7 to an optional height and operating a planting clutch for turning on and off power to the planting implement 7 and a second operation tool 24 for performing lifting operation of the planting implement 7 and performing disengaging operation of the planting clutch by single operation and performing lowering operation of the planting implement 7 and performing engaging operation of the planting clutch by another single operation. The first operation tool 22 is installed near a steering wheel 17 and the second operation tool 24 is installed in a travel gear shift lever 18. In the riding transplanter, the travel gear shift lever 18 is installed near the steering wheel 17. The planting implement 7 is composed so as to automatically lift to the height of an inoperative position, relative to a field during lifting operation with the second operation tool 24 and automatically lower to the height of an operative position relatively to the field surface during the lowering operation with the second operation tool 24.COPYRIGHT: (C)2009,JPO&INPIT【課題】植付作業機時の機体旋回操作を迅速に行うことができる乗用移植機を提供することを課題とする。【解決手段】植付作業機7を任意の高さに昇降操作し且つ植付作業機7への動力を入切する植付クラッチを操作する第1操作具22と、単一の操作により植付作業機7を上昇作動させるとともに植付クラッチの切操作を行い、他の単一の操作により植付作業機7を下降作動させるとともに植付クラッチの入操作を行う第2操作具24とを備え、第1操作具22をステアリングハンドル17の近傍に設け、第2操作具24を走行変速レバー18に設けた乗用移植機において、走行変速レバー18をステアリングハンドル17の近傍に設け、植付作業機7を、第2操作具24による上昇作動時に圃場に対して非作業位置高さに自動上昇し且つ第2操作具24による下降作動時に圃場面に対して作業位置高さに自動下降するように構成する。【選択図】図13
