Abstract

PURPOSE: To enable the running reference line to be detected with accuracy without being affected by outer turbulence, by means of setting up a reference photographic objective, a photographic device thereof, and a phtoelectric convertor at the machine body part near the position of the photographic objective by photographic device. CONSTITUTION: The first photographic device 7 by which takes the boundary part between a previously cultivates area A and a before cultivated area B, and photoelectric elements S1WS4, and the second photographic device 9 which takes the upper part of a front wheel 5 covered by a mounting panel 6 and photoelectric elements S5, S6 are arranged. The mean value of output signals from the photoelectric elements S5, S6 is operated, and is outputted to comparators 12AW12D as a reference output signal. The comparators 12AW12D output the deviated value of outputted signals from the photoelectric elements S1WS4, and a judging device 14 sums up each deviated values, and a control signal is outputted to a conducting device 13 on the basis of the extent of the sum up deviation value.
