Load space utilization of forwarder Valmet 860.4

Forwardes are most common machines used for timber extraction in Croatian lowland forests. The paper deals with mass, volumetric and length utilization of load space of eight-wheel forwarder Valmet 860.4 during extraction of timber assortments and energy wood at different methods of timber processing in oak regeneration felling. Results show that mass utilization of load space is higher than rated load capacity during extraction of technical roundwood while volumetric and length utilization less than nominal values of the length and volume of forwarder load space. The minimum value of mass utilization is determined during extraction of forest biomass/wood residuals which affects costs and profitability of such a machine in these conditions.
