“…A critical review of existing methods for carrying out selective and clear cuttings of forests under conditions of natural reforestation [11,13,18,22] allowed us to conclude that their use in conditions of double-row forest plantings will inevitably lead to damage to neighboring trees of the same row and trees of adjacent rows.…”

The article discusses the issues of logging in forest areas after artificial reforestation with a double-row arrangement of forest plantations. A critical review of existing methods for carrying out selective and clear cuttings of forests was carried out. The purpose of the study is to develop a method for felling trees with a double-row arrangement of growing trees, allowing felling without damaging neighboring trees and trees in nearby rows. As a result of the research, a modernization of the forestry tractor was proposed.

The aim of the research was to create a mathematical dependence to justify the labor costs of moving a fallen tree by harvester to the zone of its bucking, depending on the variety of values of natural factors characterizing the operation of the harvester during the partial cut of the forest. For this research, the computer simulation model of the technological process of the forest harvester was created. Production experiments were carried out to test the model. The computer experiment was implemented on the model, and regression dependence was obtained. The results of this study showed that the relationship between the residual density of plantings and the execution time of the moving operations using regression dependence. The multiple coefficient of determination of the nonlinear model was 0,845. This value indicates that the change in the average time of moving a fallen tree to the zone of its bucking depends on changes in the factors included in the regression model, and this dependence is not accidental. The results can be used by research organizations when planning the production process of logging operations.

The purpose of this research is to substantiate the mathematical regularities of the harvester operation, allowing for rapid technical calculations of labor costs with a sufficient level of reliability when performing various logging operations. The article describes the simulation model of harvester movement in the cutting area, created by the authors to analyze the operation of the harvester at various logging sites. Examples of visualization of the program and the results obtained with its use are given. Four-factor experimental plan was drawn up with varying factors at four levels. The results obtained during the simulation have been statistically processed. The analyzed elements of the cycle time are: the average time of pointing the manipulator at a tree, the average time of moving a fallen tree to the processing zone and the average time of moving the harvester between working positions per felled tree. The regression dependencies obtained as a result of the analysis are based on four indicators. Such indicators are: the total stock of wood per hectare, the share of the felled component of the stand, the amount of undergrowth (rowan, bird cherry, willow, etc.) in the cutting area, the average volume of the tree in the cutting area. The found patterns give the researcher a general idea of the effectiveness of the equipment in specific natural conditions of cutting areas. The use of the acquired knowledge in the analysis of harvester performance will improve the accuracy of planning the work of logging crews.
