<p>PROBLEM TO BE SOLVED: To optimize a planting depth, to improve planting accuracy, to improve workability, to improve operability, and to prevent the interference of a member.SOLUTION: In a seedling transplanter, a traveling device (4), a seedling transfer part (5) for transferring seedlings, a seedling planter (6) for planting the seedlings transferred to a planting supply position (A) by the seedling transfer part (5) into a farm field, and a sensor (17) for detecting a height of a farm field face are arranged, the seedling planter (6) is lift-controlled so as to be maintained at a desired grounding height on the basis of the detection of the sensor (17), the sensor (17) detects the height of the farm field face by the grounding of a main grounding portion (17a) which is wide in left and right widths and a sub-grounding portion (17b) which extends from the rear side of the main grounding portion (17a) and is narrow in left and right widths, and the sub-grounding portion (17b) is located in a center position of the left and right of the main grounding portion (17a), and in a position which is displaced to one side of the left and right of the planting supply position (A), and also in a lower position of the seedling transfer part (5) in a machine-side plane view.</p> |
