Japanese Patent JPH03132810
Kind Code:
A
Abstract:
PURPOSE:To prevent such cases where a self-traveling work vehicle travels repetitively at the same traveling position, a specific points stamped down within a work area, and a hollow is formed along a traveling locus by providing a traveling position setting means to set a traveling position with a prescribed shift secured from the preceding traveling position when the vehicle works. CONSTITUTION:A means is provided to set a traveling position with a shift secured by a prescribed extent l from the preceding traveling position at the next work of a vehicle. A support part 6 is shifted to the left or right by the extent l before the next work is started after the end of the preceding work. Then a self-traveling mowing machine 1 is drive over a guiding cable 5 after the shift of the extent. Thus the automatic steering control is carried out so that the cable 5 is positioned at the center of pick-up coils 7 and 8 respectively. Then the wheels 2 and 3 are shifted to the right and the left by l against the first mowing position. As a result, both wheels 2 and 3 never travel repetitivel on the same locus. Thus it is possible to prevent such inconvenient cases where a specific point is stamped down in a work area, a hollow is formed along a traveling locus, and the lawn on the traveling locus is impaired.
