METHOD FOR FELLING OF FOREST STOCK ON PLOTS Russian patent published in 2007 - IPC A01G23/00 A01G23/02 

FIELD: logging industry, in particular, processes for felling of forest stock.

SUBSTANCE: method involves felling forest stock on timber compartment restricted by compartment lines; providing main skid roads perpendicular to one another with intersection point at the center of compartment, with plots formed upon dividing of compartment by main skid roads into parts being rectangular. Joint sub-compartment attraction zones adjoining to main skid roads are formed as rectangular triangle defined by main skid roads and process corridor laid in parallel with straight line connecting leading points of main skid roads. Attraction zones adjoining to compartment lines are shaped as quadrangle defined by compartment line, main skid ride plot adjoining to said compartment line, process corridor and diagonal line of compartment. Swath roads of attraction zones adjoining to main skid roads are laid in parallel with process corridor, and swath roads of attraction zones adjoining to compartment boundary are laid perpendicular to nearby compartment lines.

EFFECT: reduced average distance for logging from compartment and, consequently, reduced labor costs associated with timber logging.
