In the Blacksea region located in north of Turkey, timber extraction with skidding vehicle is the most common system and also the one that tends to cause the erosional problems. The combination of the timber type and topography limit harvesting mechanization to perform transport operations. Rubber tires tractors are used on the more gentle slopes and on skid roads on steeper terrain. In this study, productivity of New Holland farm tractor in beech stands was performed in the area of Gurgentepe Local Forest Enterprise within the Ordu Forest Administration in Turkey. Timber was skidded uphill by New Holland farm 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 140 and 320 m. Hourly productivity are 11.350 m³/hour for skidding distance of 140 m, 7.700 m³/hour for skidding distance of 320 m. The cost of skidding are 4.5 m³/$ and 8.6 m³/$ as different distance. The average fuel consumption are 6.0 l/hour.
