FIELD: forest industry, in particular, performing of cutting area works.
SUBSTANCE: method involves dividing cutting into plots, each of said plots being divided into swaths-triangles whose apex is defined by spar; laying swath logway in the mid portion of swath; dividing swaths into strips extending in parallel with swath logway; felling trees on strips; attaching trees or tree lengths felled onto strips adjoining to logway to working cable of rope unit; moving trees or tree lengths to spar and uncoupling from working cable; felling trees from strips remote from logway onto butt parts of trees or tree lengths felled onto strips adjoining to and positioned close to logway so that their axes coincide to maximum extent with one another; securing butt parts of trees or three lengths felled onto strips adjoining to and positioned close to logway with apex parts of trees or tree lengths felled onto strips remote from logway and using as guiding and supporting members during movement onto logway of number of trees or tree lengths secured with one another, with first of said trees or tree lengths felled onto strip adjoining logway being coupled to working cable of rope unit.
EFFECT: increased width of swath, reduced area for logways, reduced hazard to environmental nature during logging of wood, reduced number of movements performed by cable during forest operation, and increased efficiency of logging technique.
