The intermediate portion of the second elevating arm 22 protrudes from the right side of the rear side of the fifth case portion 18e, and is fixed to the second drive shaft 27 that is driven and rotated, and the distal end portion of the second drive arm 28 that is driven and rotated. It connects so that it can rotate freely.

  Therefore, when the first drive arm 26 and the second drive arm 28 are driven and rotated by transmission of power by the transmission mechanism in the planting transmission case 18, the first lift arm 20 and the second lift arm 22 are moved up and down while swinging. As a result, the lower end of the seedling planting body 4 moves up and down while drawing a trajectory T as shown in the drawing. The beak-like seedling planting body 4 opens when it descends to the lower end of its lifting locus, and releases the seedlings in the seedling planting body 4 to the soil in the field.

  MT shown in FIG. 9 is an up / down trajectory during operation including forward movement of the lower end portion of the seedling transplant body 4 of the seedling transplanting machine according to the present example by forward movement of the body. The raising / lowering locus MT during operation of the lower end portion of the seedling planting body 4 moves rearward from the descending start point which is the upper end of the raising / lowering locus MT toward the lower end point which is the lower end of the raising / lowering locus MT while moving to the rear side of the aircraft.
