To solve problems in which a weight sensor is readily swingable and control by the weight sensor is readily influenced by vibration of a machine body, and stabilization of detection and rolling control is made difficult and constitution of the weight sensor is also complicated, though the weight sensor in which detection of left and right tilting angle is carried out by hanging a weight down in order to detect left and right tilting state of a vehicle body is frequently used.
In a posture controller of a rice transplanter, a pair of main sensor 1 and subsidiary sensor 2 for detecting soil face height of left or right planting row position is arranged and pitching control for lifting or lowering left and right both wheels 4 and 5 to a vehicle body 3 is carried out, based on detection of the main sensor 1, and rolling control of the vehicle body 3 is carried out by lifting or lowering the wheel 5 on this side, based on detection of the subsidiary sensor 2.
