Productivity of MB Trac 900 tractor at beech stands on mountainous areas in Blacksea region

Abstract

Research of productivity of MB Trac 900 tractor in beech stands was performed in the area of Golkoy Local Forest Enterprise within the Ordu Forest Administration in Turkey. Timber was skidded uphill by MB Trac 900 tractor in felling area. Time study of a cycle was carried out by using collected data and by statistical analysis. In this study, skidding distance ranges between 55 and 105 m. Hourly productivity are 14.400 m(3)/h for skidding distance of 55 m, 8.700 m(3)/h for skidding distance of 105 m. The cost of skidding are 3.5 and 9.6 $/m(3) at different distance. Average load volume for every cycle was found 1,490 and 2,130 m(3), respectively.
