PROBLEM TO BE SOLVED: To provide a seedling transplanting machine that can perform a control action according to an intention of a worker.SOLUTION: A seedling transplanting machine includes: a seedling platform 51 moving left and right reciprocally a planting clutch mechanism 120 for selecting an on-mode or an off-mode as a transmission mode of the driving force to the seedling platform 51 a wheel 11 rotated by using the driving force transmitted from an engine 20 through a main transmission 23 a sub shift lever 100 for selecting the transmission mode of the driving force to the wheel 11 according to a lever operation position an edge approach mode selection member 150 for selecting an edge approach mode for making the seedling platform 51 approach and stop to any one side end of left and right according to operation and a main gear shift lever 111 for instructing an output value of the main transmission 23. When the edge approach mode is selected, the output value of the main transmission 23 is configured to be zero regardless of the operation position of the main gear shift lever 111, if the operation position of the sub shift lever 100 is not in a neutral position.SELECTED DRAWING: Figure 3
