In this case, since each lever 46a, 46b, 46c is bent toward the driver's seat side, it can be easily grasped from the driver's seat 7, and the length of the central lever 46b is different from that of the other lever 46b. Since it is formed longer than the levers 46a and 46c, the position of each lever can be easily identified.

  Here, a case will be described in which only four spaces are left on the heel and seedlings are planted by two rightmost strips. The rightmost two strips are operated by tilting the lever 46a in the vertical direction, pulling the pinning wire 50a connected to the rear end of the lever 46a, and the vertical feed clutch wire 27b branching from the pinning wire 50a, and the planter clutch wire Through 28b, the longitudinal feed clutch 26a and the planting streak clutch can be cut and fastened, respectively. When the driving power is cut off by cutting the vertical feed clutch 26a and the planting streak clutch, the vertical feed belt 26a stops and the mat seedling is stopped, and the planting rod 23a stops and the right two strips stop. Seedling planting stops. On the other hand, the clutch shifter wire 38a connected to the rear end of the lever 46a cuts the clutch mechanism of the fertilizer transport device via the clutch shifter lever 37a, and stops the fertilizer discharged from the fertilizer feeding case 33a.

  The paddy field work machine in which the right two lanes are stopped by the operation of the lever 46a is operated in the center and left four lanes while traveling in the space left on the shore, and seedling planting is performed again. Similarly, the lever 46b is used to stop the two central strips and the lever 46c is tilted to stop the two left strips, and the corresponding stripping device 20 and fertilizer 30 are stopped. To do.

  As described above, the stapling lever 45 is attached to the fertilizer frames 31 a and 31 b of the fertilizer application device 30, so that when the fertilizer application device 30 is attached to and detached from the traveling machine body 1, the stapling lever 45 is also attached and detached at the same time. The operation | work which attaches / detaches the lever 45 separately becomes unnecessary. Further, the stapling of the planting device 20 and the fertilizer application device 30 is operated by tilting one of the levers 46a, 46b, 46c of the stapling lever 45 in the vertical direction, so that the lever operation is easy and an erroneous operation can be prevented. . Further, since the stapling lever 45 is arranged on the opposite side of the seedling supply device 10, for example, when the spare seedling is replenished from the seedling supply device 10 to the planting device 20, the operator's leg is connected to the stapling lever 45. Inadvertent contact stops will not occur.

  Finally, the embodiment according to the present invention describes the best mode of the anchoring lever that can be used for the paddy field work machine as one embodiment, and is not limited to the fertilizer 30 for fertilizing the above-mentioned granular fertilizer. It can also be used for a fertilizer applying fertilizer. Moreover, the seedling supply apparatus 10 can be diverted to a paddy field machine using a seedling supply apparatus that is vertically stacked, in addition to the front, rear, and low inclination postures shown in FIGS. 1 and 2.
