Abstract

PURPOSE:To facilitate accurate detection of the growth density of lawn, by storing a prescribed number of the signals informing the state of light-receptor in a memory means every time when a running distance of a vehicle reaches a prescribed level and judging the lawn in dense state when the light-receptor is frequently out of light-receiving state. CONSTITUTION:The objective detector is provided with a light-emitting part to project signal light along the lateral direction of the vehicle and a light- receiving part to receive the light signal projected from the light-emitting part. A memory means 103 stores a prescribed number of the states of the light- receptor, i.e. the detection states of the optical sensors S1, S2 every time when the running distance of the vehicle reaches a prescribed level. When the number of the states of the optical sensors S1, S2 shielded from light with the lawn is large, the growth density of lawn is judged to be dense by the judging means 104 according to the information transmitted from the memory means 103. The detection is performed according to the program stored in a controller H.
