  According to the feature of claim 4, since the rod member has a contact portion that stops the rotation of the rod member by screwing the screw member into the screw portion of the rod member by contacting the battery, the screw member is connected to the rod. When the rod member tries to rotate together with the screw member when screwed into the screw portion of the member, the rod member tries to rotate together with the screw member because the contact portion of the rod member contacts the battery Is stopped.
  In this case, when the contact part of the rod member contacts the battery, the state in which the rod member tries to rotate together with the screw member is stopped, and the contact part of the rod member is received. Since the battery which is an existing member is used as the member, it is not necessary to provide a dedicated member for receiving the contact portion of the rod member.

As the aircraft advances, the center float 13 follows the surface of the rice field, and the height of the center float 13 relative to the seedling planting device 5 is detected from the detected value of the potentiometer, so that the seedling is transplanted from the surface (center float 13). The height up to the attaching device 5 can be detected.
[0040]
[6]
  When the elevating lever 55 is operated to the raised position, the planting and fertilizing clutch is operated in the disconnected state by the electric motor 65, and the seedling planting device 5 is driven up by the hydraulic cylinder 4. An upper limit sensor (not shown) for detecting that the seedling planting device 5 has reached the upper limit position is provided, and when the upper limit sensor detects that the seedling planting device 5 has reached the upper limit position, The cylinder 4 stops. When the elevating lever 55 is operated to the neutral position, the planting and fertilizing clutch is operated in the disconnected state by the electric motor 65, and the hydraulic cylinder 4 is stopped.
[0041]
  When the elevating lever 55 is operated to the lowered position, the planting and fertilizing clutch is operated in the disconnected state by the electric motor 65, and the seedling planting device 5 is driven downward by the hydraulic cylinder 4. In this case, when the center float 13 contacts the rice field and is detected by the potentiometer, the height of the center float 13 relative to the seedling planting device 5 (the height from the rice field (center float 13) to the seedling planting device 5). )) So that the seedling planting device 5 is maintained at the set height from the surface (so that the detection value of the potentiometer (the vertical distance between the potentiometer and the center float 13) is maintained at the set value), The hydraulic cylinder 4 is expanded and contracted, and automatic raising / lowering control in which the seedling planting device 5 is automatically driven up and down is started. Thereby, the seedling planting device 5 is driven downward, and apparently the seedling planting device 5 automatically stops on the paddy surface.
[0042]
  When the elevating lever 55 is operated to the planting position, the electric motor 65 operates the planting and fertilization clutch to the transmission state, and the above-described automatic elevating control is performed. Thereby, the seedling planting apparatus 5 is maintained at the set height from the rice field, and the planting depth of the seedling by the planting arm 12 is maintained at the set value.

  When the elevating lever 55 is operated to the automatic position, the operation lever 70 functions as follows, and when the elevating lever 55 is operated to the raised position, the neutral position, the lowered position, and the planting position. The operation lever 70 does not function. Thus, when the operating lever 70 is operated to the raised position in the state where the lifting lever 55 is operated to the automatic position (even if the operating lever 70 is operated to the neutral position), the electric motor 65 is operated. As a result, the planting and fertilizing clutch is operated in the disconnected state, and the seedling planting device 5 is driven to rise to the upper limit position by the hydraulic cylinder 4.
[0045]
  When the operating lever 70 is operated to the lowered position while the lifting lever 55 is operated to the automatic position (even if the operating lever 70 is operated to the neutral position after being operated to the lowered position), planting is performed by the electric motor 65. The seedling planting device 5 is driven downward by the hydraulic cylinder 4 until the fertilizer clutch is operated in the disconnected state and the center float 13 contacts the surface. When the center float 13 contacts the surface, the above-described automatic lifting / lowering is performed. The control is started, and the seedling planting device 5 apparently automatically stops on the paddy surface.
  As described above, when the operation lever 70 is operated to the lowered position, is operated to the neutral position, and then is operated to the lowered position again, the planting and fertilizing clutch is operated to the transmission state by the electric motor 65.

The position of the lifting lever, position sensor, and detent mechanism is determined accurately by the fact that the sensor and detent mechanism are provided, so the detection accuracy of the operating position of the lifting lever and the holding accuracy at the operating position of the lifting lever are improved. I was able to.
[0053]
  According to the feature of claim 4, the “effect of the invention” of the above-described claims 1 to 3 is provided as in the case of any one of claims 1 to 3. The following “effects of the invention” are provided.
  According to the fourth aspect of the present invention, when a battery is provided on one lateral outer portion of the right or left vertical frame and the battery is fixed by the rod member and the screw member, the screw member is screwed into the screw portion of the rod member. At this time, the state in which the rod member tries to rotate together with the screw member is stopped, and the screw member can be screwed into the screw portion of the rod member without any trouble. In this case, a battery that is an existing member is used as a member for receiving the contact portion of the rod member, and it is not necessary to provide a dedicated member for receiving the contact portion of the rod member. It became advantageous.
