A machine for thinning young stands comprises a wheel-mounted chassis and a feller assembly for a crane which in addition at least to a boom carrying the feller assembly has a mount arranged on the thinning machine. The crane mount and the driver's cabin for the machine are arranged on a common platform which is rotatable about an axis contained in a plane of symmetry extending through the machine. In conjunction with the crane mount and the driver's cabin there is provided a free space adapted, when the occasion arises, to accomodate the feller assembly and a stem grasped thereby. Both the driver's cabin, the crane mount and said space are located within an imaginary circle the diameter of which is substantially at most equally large as the largest width of the machine. As a result, the driver's cabin, the crane mount and the feller assembly and said stem will, when the crane is swung, be contained within the space of the ground area occupied by the machine independently of the swing angle position of the platform. |
