An overview of work productivity evaluation of farm tractors in timber skidding operations

Farm tractors have been applied in forest operations to carry out several tasks such as tree/felling/process-ing, forwarding, loading, skidding and cable yarding. can be equipped with special logging equipment that allows for their safe efficient work the harvesting of stands. This research is aimed collect review available literary sources on productivity farm during operations. The study results showed timber has studied by researchers around world. According results, reported varied from 1.2 m 3 /PMH 0 15.8 among international studies. Main variables impacting included distance, load volume, number pieces per turn, tree diameter, length, slope skid trails engine power. Proper trail planning, applying suitable (e.g. winches, sulkies etc.), considering size prop-er safety standards all help improving efficiency extracting. information provided this industry users gain proper knowledge skidding. also useful planning development purposes within small-scale
