[0001]

[Industrial applications]

 The present invention relates to a ridge coating device for mechanically forming ridges in a paddy field by a ridge shaping plate.

[0002]

[Prior Art]

 The current ridge coating device of this type uses a tractor rear mounting method in which a ridge shaping plate is mounted up and down via a three-point link mechanism behind the tractor.

[0003]

[Problems to be solved by the device]

 However, in the case of such a tractor rear mounting method as described above, not only the work efficiency is extremely poor because work cannot be performed up to the ridge end and the rest depends on human power, and the work performance of the ridge coating device itself is also poor. It had the drawback of being greatly affected by performance.
