In such a configuration, when performing work, the tractor 1 to which the working machine 4 is connected is run in a work area where rotary tilling has been performed in advance. Then, as the tractor 1 travels, the disc 6 crushes the portion depressed by the tractor 1 and brings the soil inward. The ridge shaper 12 further moves the soil inward, and the ridge shaper 12 further moves the soil. Ridge 10 and three ridge grooves 11 are shaped.

Here, inside the front end side of the ridge shaper 12, a crushing blade 28 is rotationally driven.
Is rotationally driven to form a finely crushed fine soil portion 10a on the surface layer at the center of the ridge 10 in the process of being shaped by the ridge shaper 12. Therefore, even when the ridge shaping operation is performed under the condition that a large amount of water is contained in the soil, such as after the rain, a large soil mass is prevented from appearing on the surface layer of the ridge 10. Therefore, when seedlings such as vegetables are planted in the narrow soil portion 10a, the planting ability of the seedlings is improved, the seedlings are prevented from falling down, and the seedlings are more enthusiastically improved. For this reason, the initial growth of the seedlings is improved, and all the seedlings grow evenly. Thus, the irregularity of the crops at the harvest time is prevented, and the deformation of the crops is prevented, so that a crop having high commercial value can be harvested.

The earth lift belt 33 is driven by the power transmitted from the tractor 1 via the transmission and the joint, and a part of the earth is earthed from the front of the ridge shaper 12.

The ridges 10 and the ridges 11 shaped by the ridge shaper 12 are covered with the multi-film 15, and a tread wheel 16 advancing in the shaped ridges 11 steps on the multi-film 15. Thereby, the multi-film 15 wound in a roll shape is drawn out and the ridges 10 and the ridge grooves 11 are smoothly covered.

Next, in this operation, FIG.
As shown in FIGS. 2 and 4, the cover disc 21 is grounded by turning one lever 18 downward, and the cover disc 2 is turned by turning the other lever 19 upward.

The earth covering disk 21 is grounded on the side of the ridge groove 11 facing the unworked area where the work is to be performed, and the earth covering disk 2 is located on the side of the ridge groove 11 facing the already worked area where the work has already been completed.
2 is kept away from the ground.

Here, in the ridge groove 11 to which the covering disk 21 is grounded, one side of the multi-film 15 covering the ridge groove 11 is covered by the covering disk 21 and the ridge 10 has a skirt. Sent. on the other hand,
The shooter 31 is rotated to a position facing the ridge groove 11 where the soil is not covered by the soil covering disk 21, and when the shutter 35 is opened and closed at a predetermined timing, the soil lifted by the soil lifting device 30 is ridged. It falls intermittently on the multi-film 15 covering the groove 11. In this manner, the ridges 10 and the ridge grooves 11 are shaped and the shaped ridges 1 are formed.
0 and the ridge grooves 11 are coated with the multi-film 15.

Next, the tractor 1 is moved to the end of the working area by U
A case where the work is continued on the return path after the turn will be described with reference to FIG. First, the two ridges A ₁ and A ₂
Are ridges shaped in the outward stroke shown in FIG. 4, and these ridges A ₁ and A ₂ and ridge grooves a ₁ and a ₂
Is coated. On the other hand, in the ridge-furrow a _3, once one side of the multi-film 15 that covers the furrows a ₃ is biased to the skirt portion of the ridge A ₂ together are covered with soil by soil covering disc 21. When the tractor 1 having made a U-turn is run, the lever 18 is rotated upward to separate the covering disc 21 from the ground, and the lever 19 is rotated downward to ground the covering disc 22. When the tractor 1 travels in this state, the two ridges B ₁ , B ₂ and the three ridges b ₁ , b ₂ , b ₃ are shaped as the tractor 1 travels, and the multi-film 15 is coated. It is. In addition,
One side of the multi-film 15 coated with furrows b ₃ is, as in the previous step, being biased to the skirt portion of the ridge B ₂ together are covered with soil by soil covering disc 22.

Here, in the ridges a ₃ and b ₃ facing the non-working area where the work is to be performed, the multi-film 15 is covered with the soil, and the ridges A ₂ and B ₂ are offset to the bottom. Therefore, when performing the operation of the next step, the ridge shaper 12 is prevented from being caught on the multi-film 15 covered in the previous step and tearing or peeling the multi-film 15. Moreover, the ridge a shaped in an overlapping state
_3, in b ₁ it is not be said that the multi-film 15 is coated overlap is coated in single state. Therefore, even if a hole is previously formed in the portion covering the ridges in the multi-film 15 in order to improve the permeability of water into the soil, the hole is closed by another multi-film 15. This prevents water from penetrating into the soil in all the furrows.
