The purpose of the present invention is to set an appropriate tree interval within a tree interval setting range corresponding to a traveling speed. A seedling transplantor comprises: a traveling vehicle body, a planting unit disposed at the traveling vehicle body to plant seedlings in package elements; a planting clutch (420) for turning on or off the vibration to the planting unit; a solenoid (470) for switching the planting clutch (420) at a predetermined operation timing; a shift lever for setting one of multiple kinds of traveling speeds of the traveling vehicle body; a memory (810) for containing the control ranges of multiple plating intervals corresponding to the multiple kinds of traveling speeds; a display unit (630) for displaying the control range of a planting interval corresponding to the traveling speed; and a controller (800) for determining the planting interval selected within the control range of the planting interval displayed on the display unit and the operation timing of the solenoid (470) based on the set traveling speed. |
