The invention concerns a system for the processing and transport of forestry material by means of terrain-going vehicles (1A, 1B) such as forestry machines and where the material, after harvesting, is intended to be transported from the felling site (5) to consumers. In order to achieve improved efficiency, the system includes a vehicle combination consisting of； a) a first vehicle (1A) that can be driven and that is equipped with a driver's cabin (15) and supports a harvester unit (3) at a free end of a crane arm (2) that can, through operation of the crane, carry out harvesting within a practical working area (17) within a defined working sector, b) a second vehicle (1B) without a driver's cabin (15) that supports a timber-receiving unit (11) at a crane arm (10), and which second vehicle is provided with a load compartment (12) for the transport of tree trunks, c) coupling means (14) with which the second vehicle (1B) can be coupled to the first vehicle (1A), d) a loading system that, through it being arranged to reach into the practical working area, allows the timber-receiving unit (11) to receive and carry timber in a retaining manner directly from the harvester unit (3), and to displace timber to a position in and above the load compartment (12).
