Forest fires are studied and developed in all countries with forest resources. However, despite large number of studies, the problem is still far from being resolved and fires still cause great damage to forests. The article deals with research on the influence of the screw drum parameters on the quality of removing the surface soil layer from combustible materials and on the performance of the forest fires soil-sweeping machine. The geometric parameters of the screw drum of the forest fires soil-sweeping machine were optimized. As a result of optimization, the optimal values of the screw channel depth in the range of 7.5-8.7 cm and the screw pitch of 23-40 cm were obtained. At these optimal values, the ground cover content in the thrown soil stream will be less than 15 %, the productivity of the forest fires soil-sweeping machine will be more than 40 kg/s, and the power consumption will be less than 12 kW.
