In year 2005 the Slovenj Gradec forest company decided to provide tractor LimbLuxs 80, which is the subject of this assignment. With introduction of this tractor in the forest production appeared a demand for new gathering data about suitability and usefulness of the machine. Field time measurements were done in august, 2007 in Čemernik, in the forest unit Mežica. 154 cycles of downhill wood skidding were measured use snap - back method of time measuring and measuring of the over bark. All skid roads and auxiliary storages were also measured. The data was wrote down in ajusted recording papers. Later on the data was computer processed. The results show normal structure of working time. The part of auxiliary productive time is relatively high which is effect of work condition and work organization. Comparison with the state standard times was not done, because we only have measurements of downhill wood skidding and relatively an easy working field for wood harvesting.
