In this case, it is possible to respond without difficulty through the universal joint. In addition, since the power transmission mechanism between the first drive shaft and the ridge drive shaft is configured using a universal joint, simplification of the mechanism can be achieved as compared with a case in which this is configured by a gear device or a chain device, for example. Can be planned. As a result, it is possible to further contribute to simplification of the structure of the entire ridge forming machine, cost reduction, and downsizing of the ridge forming machine.

In the ridge forming machine according to the present invention, since the rotation direction of the embankment rotor is set so as to cut into the rice field in a direction away from the foot of the old ridge, the embankment rotor is Also, when scraping the soil while shaving the inner part of the old ridge, it will be easy to cut in from the relatively hard inner part. Therefore, the soil can be scraped up with less load. Therefore,
As in the above-mentioned conventional ridge forming machine, the driving device does not need to be configured to have a large horsepower.

In the present invention, since the rotation direction of the embankment rotor is set so that it cuts into the rice field in a direction away from the foot of the old ridge, the soil on the moist and soft rice field is mainly used. It can be supplied on the old ridge in a finely crushed state. Therefore, by the compaction by the ridger, it is possible to form a firmly strong and stable ridge.

When using a conventional ridge forming machine that rotates the rotating rotor in the opposite direction, as described above, in order to scrape the soil of the old ridge upward from the hem, a dry and hard old ridge is used. There was a problem that the soil of the ridge was easily scraped up in a large lump state, it was difficult to compact the embankment at the time of arranging, and it was easy to form a ridge with rough grain and unstable strength, but the present invention solves this problem It has great advantages.
