AB  - In Turkey, mechanizedharvesting methods have started to be used depending on the recent developmentsin forest industry, but advanced harvesting machines could not be used innational wide due to high operating cost and terrain conditions. The mostcommon harvesting method is skidding with farm tractors since they are easilyaccessible and cost efficient. In this study, skidding method by a farm tractorin Bigadic Forest Enterprise Directorate was examined in terms of productivityand cycle time. The factors that affect the machine performance were alsoevaluated. It was found that the average time measurement of a cycle was 30.75minute and the average productivity of tractor was found to be 4.75 m³/hour.The average volume and amount of skidded timber per cycle was about 1.80 m³ and2 pieces, respectively. Among the factors evaluated in the study area, it wasfound that skidding distance had a maximum effect on the total cycle time andproductivity. Unlike previous time studies, it was found that volume wasrelatively less effective on the total cycle time. This study revealed that theexamination of the total time and productivity in
