The article considers the problem of cleaning up forest debris caused by fallen dead wood or wood natural mortality (WNM). Solution to the problem of cleaning and utilization of the WNM and quality control of these sanitary measures in forest was proposed. For conditions of “Medynskiy forestry” enterprise it was proposed technological process of cleaning forest from the WNM. A mathematical model and a conceptual model of the technological process were developed. The maximum values of the utilization coefficients of the winch and the feller are achieved at 30-meter length of the rope (Figure 8). With the increase in the volume of the WNM, the utilization coefficient of the winch increases, and the utilization coefficient of the feller are falls (Figure 9). However, these changes are insignificant (no more than 3.5%) and may not be taken into account in practice. Therefore, for the conditions adopted in the experiments, the length of the traction rope equal to 30 m can be considered optimal for portable hand winches.
