制御装置。 Lift arms 5, 5 are attached to the rear of the tractor 1.
A position detector 28 is provided at the pivot base of the lift arms 5, 5 to detect the height above the ground of the rotary tiller 12 connected thereto. 12 includes a main cover 15 that covers the upper part of the tiller and rotates around the axis of the tiller shaft; a detector 27 that detects the amount of rotation of the rotary tiller 12 with respect to the fixed machine frame; and a detector 27 at the rear of the main cover 15. A rotation angle detector 30 is provided to detect the angle of inclination of the pivotally mounted rear cover 16 relative to the ground, and the set value set by the tilling depth setting device 31 and the tilling depth detected by the rotation angle detector 30 match. In a rotary tiller that controls the elevation and descent of the rotary tiller, the rotation of the main cover 15 is controlled to maintain a constant longitudinal attitude relative to the machine during tilling work, and when the main cover 15 is not in operation, the main cover 15 is A tillage depth control device for a rotary tiller, characterized by stopping machine longitudinal attitude control.
