Next, the operation of the above embodiment will be described. When the rotating 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 feeding valve 25, and is blown through the feeding pipe 27. It flows into the conduit 48 on the unit side.
At this time, the input shaft 35 on the blower unit side, which has obtained rotational power from the PTO shaft of the tractor 1 at the same time, is connected to the large-diameter pulley 4.
4. The rotation is transmitted to the blower fan 37 through 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 passes through the branch pipe 50 and the fertilizer discharge pipe 56, and the tip discharge port 57 of the fertilizer discharge pipe 56.
From the field. 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 direction in which it is desired to fly due to strong winds during the operation, the discharge direction and angle of the fertilizer discharge pipes 56, 56 are adjusted as appropriate. The direction of the fertilizer discharge pipes 56 is changed by rotating the operation lever 86 in the vertical direction or the horizontal direction. For example, when the fertilizer discharge pipe 56 is to be directed upward, the operation lever 86 is rotated in the direction of arrow A about the axis of the fulcrum bolt 89 in FIG. Rotate in the direction of arrow B. And when moving the fertilizer discharge pipes 56 and 56 in the front-back direction, for example,
In order to move the lever 90 forward, the operation lever 86 is rotated in the direction of arrow C about the axis of the fulcrum bolt 90 in FIG. Needless to say, the above-described rotation adjustment can be performed in the vertical direction and in the front-rear direction at the same time.
