Attachment of the rotary-side arm 92, the support arm 93, and the rear arm 94, and attachment of the support rod 96 and the fixing member 97 are not particularly limited. I do not care. Also, the plurality of bolts of the fastening member 98 may be, for example, a combination of hexagonal bolts and nuts.

Here, as shown in FIG. 1A, a contact switch S is provided at the rear of the hopper 2, and when the rotary B rises from the ground, the rotary side arm 92 of the rotary B contacts the contact switch S of the hopper 2. Then, when the contact switch S stops the power supply to the motor 4 and the rotary side arm 92 of the rotary B is separated from the contact switch S of the hopper 2 when the rotary B descends to the ground, the contact switch S However, the power supply to the motor 4 may be performed. As a result, when the user starts tillage and lowers the rotary B, the motor 4 is driven at that timing, and the fertilizer C can be started to spread. Also, when the user finishes tillage and raises the rotary B, the motor 4 stops at that timing, and the user can be prevented from forgetting to turn off the switch at hand.

Further, in the above description, the sparging device 1 is combined with the row forming device 9, but other configurations may be combined. For example, as shown in FIG. 6, a barley stepping device 10 may be provided on the rotating shaft B1 of the rotary B. As shown in FIG. The barley stepping device 10 includes a cylindrical portion 11 and a plurality of ribs (protrusions) 12. The cylindrical portion 11 is a temporary plate (called a hub) at the center of the rotating shaft B1 of the rotary B from which the blades B2 are removed. can be used to place the center. Also, the plurality of ribs 12 are configured to radially protrude from the central portion of the cylindrical portion 11 in the radial direction. When stepping on the barley, the blade B2 is removed from the blade stopper of the rotating shaft B1 of the rotary B, and the blade stopper and the shaft key are used to attach the cylindrical barley device 10 to the rotating shaft B1 of the rotary B. Fix the part 11 . As a result, the rotating shaft B1 of the rotary B is stopped, and the user drives the tractor A so that the cylindrical portion 11 comes to the upper part of the seedling of wheat E, which is provided in advance. It is possible to damage the stems of E. wheat and then strengthen the seedlings of E. wheat. The cylindrical portion 11 rotates freely by a constant pressure of the rotating shaft B1, and the plurality of ribs 12 function as slip stoppers for blade stoppers and shaft keys so that the cylindrical portion 11 rotates smoothly.

The configuration of the cylindrical portion 11 is not particularly limited. ), and the material of the cylindrical portion 11 can be iron, stainless steel, rubber, synthetic resin, or the like. The cylindrical portion 11 is formed by, for example, dividing a commercially available tire into two at the center, sandwiching both sides of the divided tire (half-cylinder) between four left and right connecting plates, and connecting one side with six bolts. , and on the other side, by connecting with six bolts, and using the blade stopper and the shaft key from which the blade B2 is removed, a plurality of ribs 12 are used to fix the half-cylinder divided into two parts around the rotation axis B1. to form and stabilize the cylindrical portion 11 . The structure of the plurality of ribs 12 is not particularly limited. The number is set to the value of the circumference of the cylindrical portion 11/8 cm.

As described above, the present invention is useful not only for existing tractors, but also for small tractors used as riding and non-riding management machines, and a spraying device that can easily switch the spraying mode according to the type of field. and effective as a tractor.
