Abstract

PURPOSE:To slowly raise a working machine in a field of soft soil and to rapidly raise the working machine in a field of hard soil, by regulating sensitivity of control depending upon the soil hardness of the field obtained from change of the detected value of an inner sensor in rising of the working machine. CONSTITUTION:An inner pressure sensor 23 to detect inner pressure of a hydraulic cylinder raising and lowering a working machine (plow) 5 is set and hardness of soil in a field is estimated from degree of rise of the detected value of the inner sensor in rising of the working machine. In the case of a field with soft soil, sensitivity of control is made slow and in the case of a field with hard soil, sensitivity of control is made quick. Proper draft control is carried out depending upon state of the field.
