た。 This type of rice transplanter is configured so that by controlling the posture of the planting device using the rolling control mechanism, the planting depth can be made uniform in the left and right directions regardless of the left and right tilting of the machine. If the rolling control mechanism is in an operable state even when the aircraft is turning on the ground or traveling on the road, the unexpected rolling control of the planting device by this mechanism may cause the loaded seedlings to fall off or the aircraft may There was a problem in which the wheel would wander unnecessarily, making driving unstable. In particular, the headland on which the aircraft turns is often extremely rough, which causes the above-mentioned problems to occur every time the aircraft turns.

に避け得ない。 In addition, in order to avoid such problems, it is conceivable to stop the rolling control mechanism all at once when the aircraft is turning or traveling on the road, but this would require many other operations, so it is difficult to forget to operate them. This is easy to happen, and troubles like the ones mentioned above cannot be completely avoided.

特徴とする。 In view of the above-mentioned circumstances, the purpose of the present invention is to simplify the operation and ensure that the troubles mentioned above can be avoided. In the method, the rolling control mechanism is constituted by a hydraulic drive device, and the driving pump of the rolling control mechanism is provided on the downstream side of the transmission from the planting clutch interposed in the transmission system to the planting device, and The present invention is characterized in that the operation of the rolling control mechanism is stopped by cutting off power transmission to the drive pump as the planting clutch is disengaged.

を安全、良好に行なわせ得るに至つた。 In other words, the operation of the rolling control mechanism, which is necessary to avoid the above-mentioned troubles when the aircraft turns or starts traveling on the road, is automatically stopped by using the necessary operation at this time, which is the disengagement of the planting clutch. Since it can be performed automatically, there is no need for special operations, and there is no need to forget operations.
While simplifying the operation, the above-mentioned troubles can be reliably avoided, and the aircraft can turn, run on the road, etc. safely and efficiently.

して経済的に実施することができる利点がある。 Furthermore, in order to stop the rolling control mechanism by disengaging the planting clutch, the position of the drive pump of the hydraulic rolling control mechanism is devised. Compared to the case where a switch is provided to cut off the energization circuit of the electromagnetic valve of the control mechanism and this switch is installed at the cutting operation position of the planting clutch lever, this can be done without separately providing a switch or wiring. By installing the drive pump on the lower transmission side of the planting clutch, the installation distance from the drive pump to the actuator such as the hydraulic cylinder that controls the rolling control mechanism can be shortened, and the above-mentioned intended purpose can be achieved with a simple structure. It has the advantage that it can be implemented economically.
