Research Regarding Structure of Working Time in Spruce Felling with Mechanical Chainsaw Husqvarna 365

Abstract

The structure of working time in spruce felling with mechanical chainsaw Husqvarna 365 was analyzed taking into account: the actual time of cutting, engine operating time, and mechanical and manual working time. For a relevant analysis of work patterns, there were analyzed and calculated some values, respectively: time working to felling 1 m3 and corresponding percentages of the total time for mechanical and manual working time. It was found that between the diameter of breast height of the tree and analyzed times, correlations can be established, expressed by linear, logarithmic, and polynomial regression equations, whose coefficients of determination (R2 > 0.77) confirm the significant and very significant relationship between analyzed parameters.
