PROBLEM TO BE SOLVED: To provide a transplanter having an automatic inclination controlling (horizontal controlling) function of the transplanting part, preventing the influence of the delay of the inclination sensor or a noise signal on the automatic inclination control and performing stable automatic inclination control. SOLUTION: A level control motor 16 is driven based on the detection value of an inclination sensor 18 to automatically control the inclination posture of the transplanting part 3 of the riding transplanter. The transplanting part 3 has an angular velocity sensor 19 to detect the speed of the lateral inclination of the transplanting part. The lateral inclination direction of the transplanting part 3 is judged by the detection value of the angular velocity sensor 19 and, separately, the inclination direction of the transplanting part 3 is judged by the present detection value and the past detection value of the inclination sensor 18. When these judge results are different, the output to the level control motor 16 is stopped. COPYRIGHT: (C)2004,JPO&NCIPI
