Abstract

PURPOSE: To implant young rice plants in straight line, by optically detecting the deviation of vehicle related to the left and right direction of machine to the plants already implanted and by making steering with the instruction of steering angle on the detected value.
CONSTITUTION: The sensor 20 is fitted at the external side of machine so that the center position (cross point of the light beams P1 and P2) can be positioned to the row center of the outermost part formed with plants q already implanted, that is, the row Q not implanted, and if the light beams P1 or P2 is interrupted with the plant q, the rectangular pulse detection signal R1 or R2 is outputted. The control circuit 31 detects the deviation between the relative position of the implanted plants and machine body viewed with the sensor 20 and instructs the steering angle depending on the detection value.
