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 m³/h for skidding distance of 55 m,
8.700 m³/h for skidding distance of 105 m. The cost of
skidding are 3.5 and 9.6 $/m³ at different distance. Average
load volume for every cycle was found 1,490 and 2,130 m³,
respectively.
Key words:
MB Trac 900, skidding, productivity, cost, time study. |
