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.

Apparatus for controlling traveling of mower

A transmission type light sensor is disposed in the vicinity of the exit of a shooter, which has the exit thereof positioned above a grass-bag opening, and the fullness of the grass-bag is detected when the light blocking state of the sensor continues longer than a predetermined time. A light emitting portion and a light receiving portion of the light sensor are positioned opposite to each other so that their optical axes are in coincidence, and they are firmly attached to both ends of a light sensor mounting member. The light sensor consists of a light sensor main body which is placed at one side of a cover, and a retroreflective board placed at the side of the cover opposite to the light sensor main body for reflecting incident light from the light emitting portion in the direction of incidence.
