である。[Problems to be Solved by the Invention] Generally, deep plowing
Moreover, when crushing soil, it is important to smoothly treat the soil that runs around the cultivating part, and it is effective to make a large space above the rear part of the cultivating part. In the case of the above-mentioned two-divided cover, the effect of greatly changing the space at the rear upper part of the tilling part is small, and the one that adjusts the upper part of the tilling part independent of the tilling adjustment is readjusted each time the tilling depth is changed. It is annoying. Therefore, the present invention smoothly processes the soil carried around to the front of the cultivating part during the deep crushing soil work,
In addition to reducing the horsepower consumption, the movement of the rear two-divided cover is interlocked with the tillage depth adjusting device so as to follow the shape of the rear cover of a general rotary during shallow plowing.
