PROBLEM TO BE SOLVED: To provide a transplanter capable of forming a mounting table suitable for the shape and area of a container for storing seedlings, capable of stably loading the container and efficiently removing it. SOLUTION: A vehicle body 10, a seedling feeding device 200 for feeding and feeding seedlings, seedling planting tools 310, 320 for receiving the fed seedlings and planting them in a field, and a spare seedling for feeding to the seedling feeding device 200. In the seedling transplanter including the mounting table 800 for mounting the storage container 830 for storing the storage container, the mounting table 800 is configured by a holding base 810 for holding the storage container 830 and a support frame 820 for supporting the holding member 810, and holding The platform 810 includes a bottom holding structure 811 that receives the bottom of the storage container 830, an outer peripheral holding structure 812 that is aligned with the side surface of the storage container 830, and a corner holding structure 813 that receives a corner of the storage container 830. Or two types of holding structures are used, or any one type of holding structures is used so that the shape and area can be changed.
