A new layout of a multifunctional logging machine, created on the basis of the Amkodor 2631 forwarder by retrofitting its trailer with a caterpillar mechanism, is considered. A diagram of the designed layout of a multifunctional forestry machine is presented. Preliminary calculation of the optimal contact patch of the retrofitted module of the designed machine layout is presented. The description of possible technical solutions during its operation is stated. The proposed layout allows you to expand the technical and operational indicators of the forestry machine.
