するとか、又耕深を浅くすると、耕耘カバーの前後両開
放部が増大し過ぎるため、耕耘土の飛散が過多になって
適切な耕耘状態にし難い等の虞れがある。PRIOR ART AND PROBLEMS TO BE SOLVED BY THE INVENTION In a tilling cover that covers the upper part and both left and right sides of a tilling blade installed on a rotating tilling shaft, usually both front and rear ends of this tilling cover are in contact with the tilled ground. Each cover has a fixed height and is open in the front and back directions, so for example, if the tillage depth is increased, the front and rear open parts of the tillage cover will become too small relative to the cultivated area, and the tillage cover will have to be released. There is a risk that the load will increase due to poor tillage performance, and if the tillage depth is made shallow, the front and rear openings of the tillage cover will become too large, resulting in too much tilled soil scattering and making it difficult to maintain proper tillage conditions. There is.

2) By rotating around the center, the cultivated area and the front cover (3)
Since the amount of opening of the front end of the front end, the cultivated land, and the rear end of the rear cover (4) can be adjusted according to the plowing depth, there will be no problems such as excessive load or scattering of tilled soil. There is no risk of the amount becoming excessive, and therefore the tillage state can be maintained appropriately.
