In the Brandenburg state forest, the forestry trafficability of logging tracks in a forest location classified as sensitive to traffic is being tested.
A conventional 8-wheel forwarder (Komatsu XF845-1) with a full load of approx. 33 tons is used to drive on two skid trails with comparable soil properties. Two different tire types are tested with a total of 20 passes each, which corresponds to about 5 regular timber harvesting operations.
The tests serve to analyze the influence of the tires on track formation and soil compaction. The parameters recorded and evaluated are average track depths and soil level changes in the tracks as well as soil physical parameters such as penetration resistance and shear resistance. In addition to the current volumetric soil moisture, the saturated water conductivity is also recorded as a measure of the risk of secondary soil waterlogging after traffic.
