Thus, as shown in FIG. 1, when the rotary cultivator 14 is connected to the machine body 12 to perform cultivating work, the electric power obtained by the power generator 35 is supplied to the depth sensor 17 to operate the depth sensor 17. Then, the angle of the rear cover 16 is detected. As shown in FIG. 5, the detection value of the depth sensor 17 is input to the comparator 42 as a displacement of the voltage, and a pulse is generated in the comparator 42 together with the input of the triangular wave. The width of the pulse output from the comparator 42 changes according to the change of the detection value of the depth sensor 17, and the light emitting diode 32
A light pulse is emitted from b.

The detection of the rear cover angle by the depth sensor 17 is stopped. In that case, as shown in the flowchart of FIG. 6, the output of the depth sensor 17 disappears and the control shifts from the depth control to the position control. For example, when the rotary cultivator 14 is attached to or detached from the machine body 12, the depth control is conventionally continued. Therefore, when a worker comes into contact with the rear cover, the hydraulic mechanism is activated, and the posture of the rotary cultivator 14 suddenly changes greatly. There was a risk that the operator's hands could get caught.

In order to switch to control, the posture of the rotary tiller 14 is determined by the position of the position lever, and the operator turns the rear cover 16
Even if the rotary tiller 14 comes into contact with the ground, the posture of the rotary tiller 14 does not inadvertently change, and safety can be secured.
