An arc-shaped guide hole 112 that can be inserted is an opening formed in the operation box 108. Next, the operation of the above embodiment will be described. When the rotational power of the engine 4 is transmitted to each rotating part and the machine body is advanced, the powdery or granular fertilizer filled in the fertilizer tank 20 flows down by the rotation of the feed valve 25, and is blown through the feed pipe 27. Unit side conduit 4
8 flows into. At this time, the PT of the tractor-1
The input shaft 35 on the blower unit side that has obtained rotational power from the O-axis
The rotation is transmitted to the blower fan 37 through the large-diameter pulley 44 and the small-diameter pulley 42, and the wind generated by the blower fan 37 is guided into the conduit 48. The fertilizer riding on the wind is passed through the branch pipe 50 and the fertilizer discharge pipe 56, and is sprayed into the field from the tip discharge port 57 of the fertilizer discharge pipe 56. Depending on the shape and location of the field, the spraying may be switched from uniform spraying over the entire surface to spraying on only one side. In such a case, the discharge direction may be selected by appropriately switching the shutter adjustment lever 64.
If the fertilizer does not fly in the desired direction due to strong winds during the work, the discharge direction and angle of the fertilizer discharge pipes 56, 56 are appropriately adjusted. In such a case, a single operation lever is required. The direction of the fertilizer discharge pipes 56, 56 is changed by rotating the 86 vertically or horizontally. For example, when the fertilizer discharge tube 56 is to be directed upward, the operation lever is required.
In FIG. 11, the pivot 86 is rotated in the direction of the arrow A about the axis of the fulcrum bolt 89, and when turned downward, it is rotated in the direction of the arrow B. And the fertilizer discharge pipes 56, 56
When the lever is moved in the front-rear direction, for example, when it is moved forward, the operation lever 86 is rotated in the direction of arrow C about the axis of the fulcrum bolt 90 in FIG. Rotate in two directions. In addition,
