This report is a thesis work for a B.Sc. in Forestry at the School for Forest Engineers, SLU. The aim of the work was to compare two different pricelists with the actual output from a harvester. The results have also been compared with a volume estimate of standing trees done by the Swedish Forest Agency and the “true” value registered by the Wood Measurement Association. The study confirms that the output calculated by the computer on the harvester is more reliable than the volume of standing trees estimated by Swedish Forest Agency.
