Sažetak
The paper describes the analysis of some parameters used for the calculation of the theoretical tractive performances and some other useful properties of four skidders used for wood transportation in mountain forest thinning in Croatia. Those skidders consisted of two adapted farming tractors - Steyr 9078a and Torpedo TD75a; and two medium sized skidders LPKT 40 and Ecotrac-V. These characteristics, important for dynamic performance of skidders during wood transportation, such as the height of CG, the distance of CG from the rear axle, the height of the lead point (LP), the distance of LP from the rear axle, the turning radius and the winch pull force are measured and compared with those typical for the family of rubber tired skidders determined by morphological relationship from the database made for more than 90 skidders. Calculation of the theoretical tractive characteristics will be made by the computer program developed at the Faculty of Forestry University of Zagreb before “in situ” testing which are planned by the end of this year.
