PROBLEM TO BE SOLVED: To provide a seedling transplanter performable appropriately of change and adjustment against feeding damages without requiring complicated switching operation for the setting of planting by a transplanting device.SOLUTION: The seedling transplanter includes: the transplanting device (6) for taking out seedlings from a seedling mat in synchronization with traveling of a machine body and planting the taken-out seedlings in a field a seedling interval switching device (22) and a seedling taking amount adjusting device (21). The transplanting device (6) is configured to switch the setting to the setting of the seedling intervals and the seedling taking amount counteractive to the feeding damages to seedling in the field for feeding damage-counterable planting by actuators (22a and 21a) for driving the seedling interval switching device (22) and the seedling taking amount adjusting device (21) respectively, and a control device (31) for controlling the drive of the actuators. The transplanting device (6) includes a ridge edge detecting means (23) for detecting the approach to the edge of a ridge, and the setting of the transplanting device (6) is switched to the setting for the feeding damage-counterable planting on condition that a planting position is in a prescribed range of approach along the ridge as a condition for switching the setting.COPYRIGHT: (C)2012,JPO&INPIT【課題】移植装置の植付設定について、煩わしい切替え操作を要することなしに、食害対応のための変更調節を適切に行うことができる苗移植機を提供する。【解決手段】苗移植機は、機体走行と連動して苗マットから苗株を取出して圃場に植え付ける移植装置(6)と、株間切替装置(22)と、苗取量調節装置(21)とを設けて構成され、上記移植装置(6)は、株間切替装置(22)および苗取量調節装置(21)をそれぞれ駆動するアクチュエータ(22a,21a)とその駆動を制御する制御装置(31)とによって圃場苗の食害に対抗可能な所定の株間および苗取量による食害対抗植付に設定切替え可能に構成するとともに、畦際への接近を検出する畦際検出手段(23)を設け、植付け位置が畦に沿う所定の近接範囲内であることを設定切替条件として移植装置(6)の設定を食害対抗植付に切替えるものである。【選択図】図4
