PROBLEM TO BE SOLVED: To improve planting accuracy.SOLUTION: A seedling transplanter is provided with a traveling device, a seedling transfer part for transferring seedlings, and a seedling planter for planting the seedlings transferred to a planting supply position by the seedling transfer part into a farm field. The seedling planter comprises: a drive arm 34 rotated by a planting drive shaft 91 of a left-and-right direction; a support link part 36 connected to the drive arm 34 through a front connection shaft 36a and inclined backward and downward; and a link mechanism composed of a swing link 37 which is inclined backward and upward, and in which the front end part is connected through a rear connection shaft 36b of the rear end part of the support link part 36. A seedling planting gripper 31 supported in the rear part of the support link part 36 plants the seedlings to the farm field by being operated in a trace which is long in a fore-and-aft direction. An intermediate portion between the front connection shaft 36a and the rear connection shaft 36b of the support link part 36, and a rear side portion of the swing link 37 which is on the rear side from the rear connection shaft 36b are connected by a tension spring 160 for planting and energizing. |
