A plurality of light quantity detection devices 061 each comprising a light emitting part and a light receiving part are arranged in parallel on one side of the transmission frame 7, and detect light reflected from the field. The sensor is configured to detect the boundary between cultivated land and uncultivated land based on the difference in received light. That is, boundaries are detected by utilizing the fact that in cultivated land, light is easily reflected diffusely as the field is tilled, and the amount of light received decreases to large fields.

By linking the sensor 0 and the control pulp (V) for cylinders a to displacing the rotary tilling device (11), when the rotary tilling device (3) deviates from a specific position relative to the boundary, the cylinder O barrel is moved. It is configured to operate automatically and always be located within a set range with respect to the boundary, so that the N part of the rotary tillage device (3) on the cultivated land side is at a constant position t [! 1i1ti [The control mechanism Oη has been revised to 41.

The control mechanism Q7! power supply circuit (C) [with a switch end inserted in the reed 11, and this switch end is positioned close to the operating lever for the control pulp (V) of the lift sill H, and the tilling device (3) is operated. #I is configured to act on the fifJ switch haze and close the power supply circuit (C) only when the operating lever is located in a predetermined operating range (A) for lowering to maintain the working state, Therefore, when traveling for work, the tilling device (3) is automatically moved laterally with respect to the machine body, and the edge of the cultivated land side follows the boundary TIC, allowing efficient tilling without cutting, while still being able to till the land k times. During non-working driving such as driving on the road or on the road, use the tilling device +
Based on the detection of the levitation state due to the increase in ml, the circuit (C) is opened and the controller IIIG? ) to a non-operating state, and a control stop mechanism cpV is configured to automatically stop tracking control of the tiller (3) to the boundary.

A 7-arm angle detector (Inc.) is provided at the pivot point of the 7-arm (8) to detect the angle with respect to the aircraft body, and a signal from this detector (2) is input to the first comparator, On the other hand, the signal from the first setting 11 (2), which is set to raise the tilling device (3) to a predetermined height relative to the ground, is input to the first comparator (2), and based on the comparison result, the tilling device ( 3) When the height rises to the set height, the signal is sent.
I'm configuring it to emit t-'.

The position of the tilling device (3) with respect to the transmission frame, that is, the lateral displacement lid of the tilling device (3) with respect to the fuselage, is detected by the angle of the pivot portion on the other side of both the links (l1m) and (llb). A detector is provided and configured to input to the second comparator (c), and the second comparator (2!9

Input the signal from the first comparator (2) to the comparator (c),
Only when this is input, a signal is emitted from the %2 comparator (c) based on the comparison result of the signals from the detector and the second setter (2), and the control stop mechanism FA is activated to control the hydraulic sill. The control pulp (V) t for the vehicle is configured to be operated, and the tilling device (3) is raised to a predetermined height relative to the ground, and is positioned and stopped at the left and right center or approximately the center of the vehicle, It has a safety mechanism @t-configuration so that non-working driving with the tilling device (3) raised, such as k times at the edge of the field or side, or driving on the road, can be performed in a stable state.

In addition, in order to move the tilling device (3) to the left-right center or approximately to the center with the tilling device (3) off the ground, the turning and the lateral displacement of the tilling device (3) may proceed simultaneously at the beginning of the turn.

If the tilling device (3) is moved laterally with respect to the machine body by the swinging of the recirculating link machine *Ua as in the above-mentioned embodiment, the cylinder (11) with a small stroke can be used.
