The logging machine operates as follows.

At the entrance of the machine to the nearest tree provide guidance to the working head on the butt part of a standing tree with the height of the proposed cut slope inclinations of the tree relative to the vertical. To implement this technological operations can be used: the control mechanism 10, the guidance mechanism 3, the extension beams 27 and/or the extension of the link body 4 head 5. Management processes by kinematic movement of these elements are implemented using traditionally known for these purposes, mechanisms of hydraulic motors. In versions of the harvesting machine in accordance with Fig. 1 or 2 for pointing the head 5 on standing tree provides maneuvering a wheeled chassis or the rotation of the base platform chassis. In the process guidance housing of the working head produce the capture of the wood levers 21 and 22, the subsequent cutting when the controlling influence on the cutter head. After cutting deraa cut the tree in position, appropriate processing. The translation of the working heads that hold the trunk of the tree in the correct position for processing, is carried out by rotation of the column 5 arrow 2 180owhile the tree trunk that is cut from a vertically oriented position goes in horizontally-oriented position with a corresponding orientation of the housing of the working head. When horizontally oriented position of the tree trunk part of his butt facing the drive, the vertex part in the opposite direction, i.e. in the zone of the front of the vehicle.

In the process of turning is turning arrows on the plot a curved trajectory, in particular on the semicircle in the direction from the lower extreme position corresponding to the position of the working head when cutting wood at the top, corresponding to the horizontal longitudinal orientation of the arrows in the area of the drive of the machine when the position of the head housing, creating a processing mode cut wood. Described by the end of the boom curvilinear trajectory is located in the transverse plane, which is oriented to the horizontal plane at an angle. The radius of curvature described trakto the temporary housing of the working head with the lower part of the tree trunk describe at the specified rotation arrows surface of rotation, in particular, the area of the lateral surface of a cone, the vertex of which is located at the intersection of the axis of rotation of the column and the longitudinal axis of symmetry of the working head at the extreme positions of the boom. The apical part of the cut tree and plot its trunk above the specified top section of the conical surface during rotation of the boom, form another part of the conical surface with the vertex in the previous area of the specified area, the base of this second surface is formed in the area of the top of the tree trunk that is cut at the specified rotation arrows. Described by top cut tree and part of his shaft surface rotation is conventionally from the side of the longitudinal vertical plane 1-1, opposite the conventional location relative to the specified plane of the first surface of rotation described by the arrow, the casing head and the lower butt end part of the trunk of a cut tree. Thus, acting on the axis of rotation of the column load from the weight cut wood, and the mass of the boom housing of the working head redistributed on both sides relative to the longitudinal vertical plane 1-1, hosts a column, and on the opposite nadiri processing is suspended over the machine, not touching the soil of the area, which has a positive impact on the preservation of vegetation. The centre of mass of wood in the process of moving from one position to another which does not exceed the dimensions of the machine along its width, which positively affects the stability of the machine during harvesting and wood processing.

The decrease during operation of the machine dynamic loads on the rotary column allows you to reduce the intensity of the latter when designing the machine, increased reliability, reduced energy consumption. The reduction of the consumption of the main technological equipment of the machine allows to increase its capacity, technologically necessary to increase the regular load when hauling resulting from the processing of cut wood forest products such as logs. Processing cut wood working head in its horizontal position is performed in the traditional mode of operation of harvester heads, continuous or cyclic actions.
