This study empirically evaluated the optimal length L values (length from the center of circular saw to the rear grip center of brush cutter) for five slopes by the tracking test and the subject's feelings. The study was divided into two experiments. In the first experiment, a model shaft (0.75 kg in weight) was used, and in the second one, the same model shaft was used, but 4.4 kg weight was attached to it (0.8 kg weight to the circular saw position and 3.6 kg weight to the engine position. They were considered as the circular saw and engine weight) . The results showed that the brush cutter weight (up to 5.15 kg) hardly influences the optimal length L values and the optimal length L values are 149-153 cm for a slope of -20°〜0°, 141-147 cm for 5 135-142cm for 10°, 134-138 cm for 15°〜20°. The authors suggest that the optimal length L of brush cutter should be simply adjustable at a range of 140±10 cm.
