Description

Rotorator moving left and right

The present invention relates to a rotator that moves from side to side, and in detail, it is configured to facilitate cultivation of a corner part by moving the cultivation axis and cultivation blade of the rotor as a whole from side to side.

In general, agricultural lands such as paddy fields and fields, after harvesting crops of the year, acidify the soil and harden the soil, thereby deteriorating breathability and drainage, making it difficult to cultivate crops the following year. In order to solve this, the soil is cultivated to a depth of 600 mm or more, and the soil is restored to alkali while performing a cover work to restore the soil's breathability and drainage.

Such cover work is carried out by using a rotor rotor mounted as a joint device on the tractor.
