Manufactured by the Slovene company Bijol, the articulated cable skidder is a new product. Therefore, the aim of this work was to conduct research in order to determine the structure of working day and skidding efficiency in relation to two skidding directions, slope, yarding distance and tree species. The research was conducted in the SiDG company, where 22 cycles were recorded. It was determined that average time structure is comprised of 65,67 % of productive time and 34,33 % of unproductive time. Average load equalled to 4,29 m3, while the biggest one amounted to 6,2 m3, and the smallest to 2,8 m3. Skidding efficiency was found to be higher when skidding on flat terrain (0,88 min/m3) than on a downward slope (1,53 min/m3), while skidding efficiency improves when the slope descends; with the average slope of –7,37 %, work efficiency equals to 1,25 min/m3. Both above results are the consequence of an imbalanced sample. The skidding distance affects work efficiency and equals to 0,44 min/m3 on a skidding distance of 100 m. The average daily output equals to 34,6 t. To obtain a reliable estimation of work efficiency, more field-recording is required.
