(Effect of the Invention) According to the present invention, a rear cover that rotates with respect to the rotary cover is provided outside the rotary cover, and the distance between the lower end of the rear cover and the rotary shaft is the distance between the upper end of the rear cover and the rotary shaft. Since it is larger, a lot of space can be taken between the rotary and the rear cover, and by allowing the tilling soil to flow into the space, the rotation of the tilling soil in the rotary cover can be minimized. Further, since the tilled soil smoothly flows backward in the traveling direction of the machine body, it is possible to perform efficient tilling work with less loss of horsepower. In addition, the rear cover moves up and down according to the tillage, so there is little spillage of the tilling soil to the side, and the characteristics are good.
