業時の前後バランスを阻害する虞れがある。PRIOR ART AND PROBLEMS TO BE SOLVED BY THE INVENTION In order to change the maximum plowing depth with tilling claws having a constant rotation radius, the lower end of the transmission case is equipped with a transmission mechanism that transmits power to the transmission shaft at the lower end. In a rotary tiller in which a rotary case is equipped with a transmission mechanism that transmits power from a transmission shaft to a tilling claw shaft at the lower end along this transmission shaft, and is rotatable around the transmission shaft, the area above the tilling claws is usually covered. The tillage cover is
It is fixed to the transmission case or the frame that supports the transmission case, but when the tilling claw shaft is moved upward or downward by rotating the rotating case, the gap between the tip of the tilling claw and the tilling cover changes. Since the amount of tilled soil adhering to the back surface of the tilling cover changes, the weight change of this adhering soil may impede the front-back balance during work.

発明の作用、および効果
伝動ケース（２）内の伝動機構に伝動される伝動軸（１

（３１に伝動する。Operation and effect of the invention The transmission shaft (1) that is transmitted to the transmission mechanism in the transmission case (2)
) is transmitted to the tilling claw shaft (31) via a transmission mechanism within the rotation case (4).
最大耕深は、伝動ケース（２）の下面部が未耕地表面に
接した場合に最大となるため、伝動ケース（２）に対し
て耕耘爪軸（３）が最下方位置になるように回動ケース
（４）を回動させると、最大耕深を最も深くでき、回動
ケース（４）を上方へ回動させるに従って最大耕深は浅
くなる。The maximum plowing depth is maximum when the lower surface of the transmission case (2) is in contact with the surface of uncultivated land, so rotate the tilling claw shaft (3) so that it is at the lowest position relative to the transmission case (2). By rotating the rotating case (4), the maximum plowing depth can be made deepest, and as the rotating case (4) is rotated upward, the maximum plowing depth becomes shallower.
このとき耕耘カバー（５）は１回動ケース（４）と共に
回動するため、耕耘爪の先端と耕耘カバー（５）との一
定の間隙が保持されることによって耕耘カバー（５）へ
の付着土量も変化し難く、従って耕耘作業時の前後バラ
ンスを適切に維持することができる。At this time, since the tilling cover (5) rotates together with the single-turn case (4), a constant gap is maintained between the tips of the tilling claws and the tilling cover (5), thereby preventing the tilling cover from adhering to the tilling cover (5). The amount of soil is also difficult to change, so it is possible to maintain an appropriate front-to-back balance during tilling work.
