The invention relates to the forest industry and can be used in the production of works of logging.

Currently, there are various ways to harvest using Feller-Bunchers machines (MPI) frontal type (Chernin Y.A., Bocharnikov F. W. Technology and equipment small logging and reforestation: a Training manual. - Yoshkar-Ola: Mar-GTP, 2001, p.142-144). "An indispensable requirement skidding butt forward to save the undergrowth forces off every time to return for technological corridor or one of the free bundles of ribbons in far from a loading point to the end of the tape."

When using these methods require long idle move off when switching between the tapes.

The closest in technical essence is the method proposed in A.S. 1287782. "The way of the harvest area includes a breakdown of deforestation on apiary, cutting their trees harvesting machine with stacking, limbing on skid trail, skidding whips over the top in a half-submerged position, characterized in that the laying of felled trees during felling and bunching machine from USA hauling produce the machine at an angle to the skidding rummaging, and moving to logging CCS, in front of the machine, parallel to the anee laid packs".

The disadvantages of this method include increased vulnerability of the soil cover in the plot due to the significant number of bee portages and movement of logging equipment.

The technical result obtained by the applicant, is the increase in the width of apiaries in the territory of the developed area.

The technical result is achieved in that the method of harvest, including a breakdown of documents on apiary with portages, fell trees on apiaries using Feller-Bunchers front of the machine type and placement of trees in bundles at the base of the tree, has the following features: on both sides of each bee dies pave the rounded sections, originating on the bee trail with a radius equal to the width of the tape, processed, Feller-buncher, and the center of each fillet area beekeeping trail is located at the end point of the fillet area adjacent beekeeping trail that curved to the same radius and center at the endpoint specified rounded plot, with Valka lining wood carry out the top in a direction opposite to the direction of skidding of trees, at an angle to the house rummaging, and fell trees, fallen Feller-buncher when working on curved sections bee dies, syshestvyut with the laying of the vertices on the fiber, and the butt part of the lining of the tree.

The development plan area is presented in figure 1. Figure 2 shows the technology felling of trees on the apiaries.

Cutting area 1 is divided into plots, and those in turn into the apiary, in the middle of which are laid bee 2 portages. On both sides of each bee dies laid the rounded sections 3, originating on the bee dies. The radius of the rounded sections set equal to the width of the tape, processed VPM 4. The width of the tape equal to twice the departure of the manipulator VPM (R). The center of each fillet area beekeeping trail is at the end point of the fillet area adjacent bee dies, curved with the same radius centered at the endpoint in question rounded plot.

VPM moves harvest area Shuttle method, sequentially moving from one house to the trail on the other. When the movement of the bee rummaging VPM fells the trees and puts them in packs of 5 for the top in the direction opposite to the direction of skidding. And laying felled trees when moving off from a USA hauling produce for the car, and when driving to logging CCS, in front of the machine, parallel to the previously laid packs. To improve the safety of the undergrowth on the felling felling of trees on the tape adjacent to the rounded parts of bee in the locks, is the lining the tree 6, fallen off at the entrance to a rounded plot bee dies. Roll lining of wood is made in such a way that its distal part is placed in the direction opposite to the direction of skidding of timber at an angle to bee rummaging. Trees 7, fallen off when working in the round plot bee dies, stacked on top of fiber, and the butt part of the lining of the tree. After shaky all trees that are within range of her arm, Feller-Bunchers machine returns to bee fiber. After VPM at a safe distance from her works skidder 8 with a rope-choker equipment, trellise trees for the butt for cargo item 9.

The method of harvest, including a breakdown of documents on apiary with portages, fell trees on apiaries using Feller-Bunchers front of the machine type and placement of trees in a pile on the lining of wood, characterized in that on both sides of each bee dies pave the rounded sections, originating on the bee trail with a radius equal to the width of the tape, processed, Feller-buncher, and the center of each fillet area beekeeping trail is located at the end point of the fillet participants of the bee and the adjacent track, which is curved with the same radius and center at the end point of the specified rounded plot, with Valka lining wood carry out the top in a direction opposite to the direction of skidding of trees, at an angle to the house rummaging, and fell trees, fallen Feller-buncher when working on curved sections bee dies, is done by laying on top of fiber, and the butt part of the lining of the tree.
