9 and the up / down command from the operation switch 86 conflict with each other, the command from the operation switch 85 is given priority. Thus, in an environment where judgment by an assistant who can directly look at the disks 67, 67 is given priority. The position of the disk 67 can be adjusted by the above, and an accurate soil moving action can be obtained.
Also, unintended accidents such as contact of the disk 67 with the assistant's foot can be avoided more reliably.

The downward movement of the digging blade 18 is performed by the weeding device 12.
And the like, and the gage wheel 47 is brought into contact with the ground. The gage wheel 47 in this grounded state is a moating blade 18
Irrespective of the downward movement, the carrots 12 and the like are held at a constant height from the ground g, whereby the carrots in the first row R1 are sequentially pulled out and harvested by the nipping and conveying means 7. On the other hand, the left and right discs 67, 67 rotate around the support shaft 72 in the same manner as the disc plows, and cut the soil at the ends s1, s1 of the adjacent left and right ridges U0, U1 in the direction of arrow f.
The disk 67 on the right side is pushed to 0 and f1 to move it into the groove m, and the disk 67 on the right side positions the soil at the position indicated by reference numeral n1.

Next, the ginseng in the second row R2 is harvested. At this time, the left and right traveling crawlers 2a and 2b are
12 (b), the middle of a pair of left and right starting end wheels 10, 10 is matched with the second row R2 of carrots. After that, the respective parts are operated according to the harvest of the ginseng in the first row R1. In this case, since the traveling crawler 2a on the right side is located in the groove m, the traveling crawler 2b on the left actually steps on the top surface of the soil at the location indicated by the symbol n1, and the traveling crawler 2b on the left side steps on the ridge U1. That is, the airframe travels in a significantly smaller lateral inclination state than when the aircraft travels in a state in which no soil exists in the groove m. During this traveling, the left disk 67 cuts the soil of the ridge U1 and moves the soil in the arrow direction f3, and the right disk 67 sweeps the soil in the groove m in the arrow direction f.
2 and is located at the symbol n2.

Next, the ginseng in the third row R3 is harvested. At this time, the left and right traveling crawlers 2a and 2b are
(C), the middle of the pair of left and right start end wheels 10, 10 is matched with the third row R3 of ginseng.
After that, each part is operated in accordance with the harvest of the ginseng in the first row R1. In this case, the right traveling crawler 2a is located in the groove m and steps on the upper surface of the soil at the location indicated by the symbol n2. , As in the case of the ginseng harvest in the second row R2,
The vehicle travels in a much smaller lateral inclination state than when traveling in a state in which no soil is present in the groove m. During this traveling, the left disk 67 cuts the soil in the ridge U1 and moves the soil in the arrow direction f5, and the right disk 67 sweeps the soil in the groove m in the arrow direction f.
4 to be located at the symbol n3.

Finally, the ginseng in the fourth row R4 is harvested. In this case, the left and right traveling crawlers 2a and 2b are
(D), and the middle of the pair of left and right starting end wheels 10, 10 is matched with the fourth row R4 of ginseng.
After that, each part is operated in accordance with the harvest of the ginseng in the first row R1, and also in this case, the right traveling crawler 2a is located in the groove m and steps on the upper surface of the soil at the symbol n3, As in the case of the ginseng harvesting in the second row R2, the airframe travels on a significantly smaller lateral inclination than when traveling without soil in the trench m. During traveling in this row, the left and right disks 67, 67 are preferably raised to be in a folded state. Thereafter, the same operation is sequentially repeated for the left ridge U2.

In this embodiment, the left and right disks 67,
When the movement amount and the movement distance of the soil due to 67 are insufficient, the discs 67, 67 are lowered, or the gang angle α is increased, and conversely, when they are excessive, , 67 or decrease their respective gang angles α.

When proper soil movement cannot be performed by the above-described treatment alone, a treatment for adjusting the position of the disk 67 in the left-right direction by moving the support cylinder member 55 or the extension member 52b is also performed. Thereby, the disk 67
, The soil movement process is precisely changed and adjusted over a wide range, and even if the ridge width and planting vary between fields, the lateral inclination of the machine body is effectively prevented.

The aircraft may move backward during the soil movement process. In such a case, the left and right disks 67, 67 are usually lifted on the ground g. However, there are cases where the discs 67, 67 are still located in the ground when the aircraft moves backward due to the delay of this rise. In this case, a load is applied to the discs 67 and 67 forward from the ground g.
7 and 67 are swung in the opposite direction of the arrow fa around the longitudinal axis 70 against the elasticity of the torque spring 718 and are forcibly raised. Therefore, the load acting on the disk 67 does not reach the point where the disk 67 and its supporting mechanism are damaged.

Further, since the torque spring 718 holds the disk 67 in an upright posture when the soil is moved when the disk 67 is at a certain height h1 or less, each of the disks 67 is smoothly placed on the ground at an arbitrary height position at a certain height h1 or less. It is possible to cut into the disc 67 at any height and to prevent play by eliminating play in the support mechanism.

Further, during the harvesting operation, the assistant walks along with the sorting device 39 to select defective crops. At this time, the assistant's foot erroneously steps toward the upper part of the disk 67. Even if it is lowered, the cover cv prevents the foot from contacting the disk 67. Even if another object falls onto the disk 67, the cover cv prevents the other object from directly colliding with the outer peripheral edge of the disk 67.

The soil moving means 49 of the present invention can be used in various forms without being limited to the above-mentioned use examples. In particular, the gang angle α and the scooping angle of the disc 67 are changed, and the left and right By further changing the position and the height of each disk 67, a wider range of use is possible.

As a unique use example, the left and right discs 6
The discs 67, 67 may be used in a state where the distance between the front portions of the discs 67, 67 is smaller than the distance between the rear portions of the discs 67, 67. In this case, each disc 67 is once pulled out from the support shaft 72 and turned over. By mounting in the posture, the concave surface of each disk 67 is directed to the outside of the machine body. Each of the discs 67 thus made moves the soil laterally outward of the fuselage as the fuselage advances.
