In a steering control system for a moving body in which azimuths of reference points are detected by rotatively scanning a light beam around the moving body, a current position of the moving body is calculated based on the azimuths of reference points, and the moving body is steered so that the current position thereof follows a predetermined travelling course that is calculated in accordance with an algorithm previously stored in a memory. The system assigns each detected reference point to each reference point in said algorithm for calculating the relative traveling course, based on one of a reference point that is detected first under the condition that the azimuth exceeds a first predetermined angle, and a reference point that is detected last with the azimuth being less than a second predetermined angle when the azimuth is measured with respect to the advance direction of the moving vehicle initially placed in the traveling area before the start of a work. A traveling course is set according to said algorithm using the positional information on the assigned reference points.

An apparatus for controlling the traveling of a mower comprising means for detecting the conveying state of cut grass in a shooter, and means for decelerating the traveling speed of the working machine while continuing the mowing work by the cutter and the feeding of an air flow to the shooter if the conveying state is more degraded than a jam prevention judgment criterion on the basis of the detection signal of the conveying state detector means. The conveying state of grass in the shooter is detected based on the density or amount of cut grass passing through the shooter per unit time, and the mower is decelerated while maintaining the rotation of the cutter blade for mowing and/or the feeding of the air flow into the shooter if the density exceeds a predetermined threshold value. A threshold value can be adjusted according to the condition of the grass to be cut; for example, high, degree of overgrowth, degree of dry or wet of the grass.
