Since the furrowing work is the work of restoring the old furrow in the field, the lower end of the furrowing body of the furrowing machine is aligned with the foot of the old furrow at the beginning of the work. For this reason, the tractor is operated and the work position is adjusted with the lower end of the furrowing body of the furrowing machine as close as possible to the foot of the old furrow. At the end of the work, the tractor must turn sharply from the working position at the corner of the field to change direction. For this reason, it is an operation that makes it easier for the ridge coater to contact the ridge. At this time, if the side cover is lowered more than necessary, the side cover is also likely to contact the ridge.

In fields with low ridges, it is necessary to go down to the lower action position in order for the side cover to follow the lower ridges, but in fields with higher ridges, there is no need to go down to the lower action position in order for the side covers to follow the higher ridges. like,
When it reached the position restricted by link motion, it was too low.

If the side cover is lowered too much, at the time of positioning at the beginning of the ridge coating work, the lower end of the ridge coating body of the ridge coating machine is positioned as close as possible to the foot of the old ridge by the suspension mechanism of the tractor. It is easy to make contact with the old ridge, and when changing direction at the end of work, even if the ridge coater is lifted by the suspension mechanism of the tractor, the ridge coater was tilted forward due to the nature of the suspension mechanism and dropped too much The side cover was insufficiently lifted, making it easy to come into contact with the ridge, and there was a risk of damaging the side cover.

[0006] In the case of a slope operation as shown in FIG. 6 in which the extension roller of the upper surface restoration portion of the ridge coating body of the ridge coating machine is detached, as shown in FIG. It had to be removed with a tool because it touched and damaged the shore slope.

Accordingly, an object of the present invention is to prevent the side cover of the ridge coater from lowering unnecessarily, and to be able to fix the side cover at a position that does not hinder the work.

The lower side position is restricted because the support member 90 of the parallel link is regulated by the stopper pin 91, and the lower position is unnecessarily lowered when the levee coating machine main body 2 is lifted by the suspension mechanism of the tractor. Is prevented.

Further, by changing the fixing position of the stopper pin 91, the restricting position of the parallel link changes, and the restricting position height of the lower side of the side cover 61 can be changed. Further, as shown in FIG. It can also be regulated at the non-operating position of the side cover 61.

[0058]

According to the first aspect of the present invention, the height of the side cover is automatically adjusted by vertically supporting the side cover by the parallel link, and
Since the height of the lower side can be adjusted, the side cover reliably prevents scattering of cutting soil, and the side cover lowers more than necessary when the levee coating machine body is lifted by the suspension mechanism of the tractor. This prevents the side cover from contacting the ridge and being damaged.

According to the second aspect of the present invention, in addition to the effect of the first aspect, the work is performed by removing the extension roller of the ridge-coating body upper surface restoration portion of the ridge coating machine as shown in FIG. In operation, the side cover does not need to be removed and can be fixed in the non-operation position.
