This study was conducted to determine the optimum operating conditions for the collecting device of agricultural by-product collector. A factorial experiment was performed using a test equipment with the collecting device. By targeting apple pruning branches, the collecting ratio for the branches was measured according to the rotational speed (100, 200, and 300 rpm), clearance from the soil surface (− 10, 0, and 10 mm), and forward-moving speed (0.6, 0.8, and 1.0 m/s) of the collecting device. The results were analyzed using mean collecting ratio of the triplicate experiment for each condition. Therefore, the total number of experiment is 81. Experimental results show that the collecting ratio was the highest when the collecting device was operated at 200 rpm rotational speed, 0 mm clearance from the soil surface, and 0.6 m/s moving speed. The conditions that ensured a ≥ 99% collecting ratio were 0.6 m/s and 0.8 m/s moving speed, 200 rpm rotational speed, and 0 mm clearance from the soil surface. Regarding the field capacity, the optimum operating conditions for the collecting device were determined as 0.8 m/s moving speed, 200 rpm rotational speed, and 0 mm clearance from the soil surface.
