Abstract

PURPOSE: To make less meandering and to implant yound rice plants in straight line, through direct advancement based on the deviation calculated between the plants implanted and the machine body with the signal optically detected for the position of plants in addition to the running speed of machine.
CONSTITUTION: The sensor 20 is fitted outside the macine body so that it is positioned at the mostouter part formed with already implanted plants q in the proceding process, that is, at the row center of the not implanted row Q for the center position (cross point of the light beams P1 and P2). When the light beams P1 and P2 are interrupted with the plant q, rectangular wave pulse detection signals R1 or R2 are outputted. The control circuit 31 obtains the running speed of machine body from one generated period of signals R1 and R2 and catches the time difference of producing timing of signals R1 and R2, and obtaines the deviation between the plants and machine body related to light interruption, to make steering for the reduction of deviation.
