状態にすることができる。As shown in FIGS. 5 and 6, a switch 40 is provided to the limit 1 which is pressed and operated when the operating lever 37 is swung to the operating position it or ■. A horizontal sensor 26 is connected in series to the controller 31, so that the rolling control mechanism can be switched between an operating state and a non-operating state by turning on and off the limit switch 40. . More specifically, when the operating lever 37 is in the operating position I or H, the limit switch 40 is activated, and the controller 31 operates the electric motor 18 in forward or reverse rotation based on the output of the horizontal sensor 26. Control the rolling of the Wei-Iso MB in a horizontal position. on the other hand,
When the operating lever 37 is set to the operating position/IV, the limit switch 40 is turned off and the rolling control mechanism does not operate. If the main switch 4.1 shown in FIG. 5 is installed in the vicinity of the operator operating the aircraft at the control seat 4 (J7 jF7), the rolling control mechanism can be deactivated if necessary.

When a person places the seedlings on the seedling platform 8, moves the machine forward, and moves the operating lever 37 to the operating position I, the i'i'i planting device B is moved and the seedling platform reciprocates from side to side. Planting tools 9 to 8 divide the seedlings into individual plants and send them to the soil leveling float 10.
・Plant in the field leveled in 1st and 12th stage. At this time, the drive control mechanism is in operation, so the vertical height position of the seedling planting device B with respect to the field is appropriately controlled, and the planting depth of the seedlings is maintained constant. Further, since the limit switch 40 is a human, rolling control suitable for seedling planting work is performed, and the seedling planting depth in the left and right direction of the seedling planting device RB is also maintained constant.

Even when traveling on the ground, the limit switch 40 is in position, so vertical movement drive control and rolling control are performed, making it possible to flatten the ground within the area and improve the headland on the next journey. Seedlings can be planted properly.

を防＋ｈできる。In addition, between the circuits shown in FIG. 5, at the same time that the limit switch 40 is turned on (the operating lever 37 is turned to the operating position 921 or ■), the rolling control mechanism is activated, and the limit switch 40 is turned off (the operating lever 37 to the operating position K IV), the timer is activated, and the rolling control mechanism is deactivated several seconds later.Then, the operating lever 37 is moved from the operating position ■ or ■ to the operating position IV. When the IfB is forcibly raised from the lowered position, even if the seedling planting device B is tilted with respect to the traveling vehicle body A in the lowered position, the rolling control mechanism is activated for several seconds during the forced seedling, so that the rolling control mechanism is in operation for several seconds, so that the seedling planting device B is not tilted to the traveling vehicle body A. On the other hand, the seedling planting device B becomes approximately six-flat, the aircraft becomes stable and the running performance improves, and when seedlings are placed on the seedling platform 8 of the seedling planting device B, the seedling planting device B is tilted. It is possible to prevent the collapse of seedlings caused by
