から耕耘中の土壌が耕耘カバー上方へ飛散し易い。Prior Art and Problems to be Solved by the Invention The tilling cover of the tilling device is rotatable in the front and back direction with respect to the tilling machine body depending on the tilling depth, and the position of the leveling plate covering the rear part of the tilling section is adjusted up and down. do. Generally, when the tilling depth becomes deeper, the tilling cover is rotated to the front, and when the tillage depth becomes shallower, it is rotated to the rear. For this reason, in a tilling device that has a tilling cover projecting on both the left and right sides of a transmission case that transmits power to the tilling shaft, it is necessary to move the tilling cover back and forth with respect to the transmission case. A cover hole in which the transmission case is located is formed in the center of the tilling cover, and the soil being tilled is easily scattered above the tilling cover from this cover hole.
