EVALUATING OF UPHILL TIMBER SKIDDING WITH FORESTRY TRACTOR

In our country, timber haulage operations in forestry are mostly carried out with human power, animal power and tractors. The use of tractors are inevitable as it becomes impossible to uphill transport with human and animal power when the logs place under the road. For this reason, uphill cable pulling with forest tractor have been examined in terms of efficiency in this study. The study was carried out at Cinarpinar Forest Enterprise Chief of Kahramanmaras Forest Enterprise Directorate. MB Trac 900, forest tractor performed for 10-350 meter cable skidding distances were measured by using a stopwatch during the operation by uphill cable pulling method, and then productivity calculation was done. At the end of the study, the average productivity was found to be 15.84 m3/hour, the mean skidding distance was 18,39 m, and the average timber volume was 0.40 m3.
