, a tilling device 3 is provided on the traveling vehicle body via a single-acting lift arm cylinder 6 so that it can be raised and lowered freely, a control valve 11 for raising and lowering is provided in the pressure oil supply path to the cylinder 6, and the tilling device 3 is
The rotary cover 15 is provided to be swingable, and the cylinder 6 is automatically operated to maintain the swing angle of the rotary cover 15 within a set node i based on the displacement of the rotary cover 15. (a riding type cultivator equipped with a control mechanism 21), in which the plowing depth control mechanism 21 is configured, the control valve 11 is connected to the pressure oil supply path between the control valve 11 and the cylinder 6. A return passage 13 for releasing the supplied pressure oil is connected with the valve 11 in the raised operation position, and an opening adjustment valve 14 is interposed in the return passage 13, and the opening adjustment valve 14 and the rotary cover 15 are connected to each other. The push-pull wire 1'9 is arranged so that as the rotary cover 15 swings upward, the opening becomes smaller, and as the rotary cover 15 swings downward, the opening becomes larger.
and the push-pull wire 1
The outer wire 19a of No. 9 is attached to the holder 24 so that the fixed position of the end thereof can be changed freely, and the outer wire 19a of the holder 2
