PROBLEM TO BE SOLVED: To provide a controlling technique of a grounding implement in a working vehicle for agriculture by which the control of the tilling depth is rapidly settled, and the posture control of the grounding implement to be carried out well. SOLUTION: A detection means restricts a working range based on a relative angle between a tractor 1 and a rotary tiller 14 when the rotary tiller 14 is lowered and contacts with the surface of the ground, in the tractor 1 having the detection means having both of an inclination sensor 16 for detecting the right or left inclination of the tractor 1, and a stroke sensor 17 for detecting the relative angle between the tractor 1 and the rotary tiller 14, and further having the controller for controlling the relative angle of the rotary tiller 14 based on the detection means.
