Tree Length Logging System circa 1972
(Система машин заготовки хлыстов)
Around 1972, the tree length logging system was introduced and was a major advancement over the chain saw logging system. It uses several major pieces of equipment, needing only one labor r for each machine. One machine is a feller-buncher, which cuts trees at ground level and places them in bunches. Another machine is a Skidder which drags the bunches to the landing. In most cases, two were needed to keep up with the feller-buncher. Alternatively, a forwarder machine (photo) could be used. At the landing, a delimber machine removes limbs from the trees. A slasher machine cuts the trees to appropriate lengths and stacks the logs in piles for truck transport. The tree length system can be very productive, but only if the labourers are there for each machine, each machine was working, and the weather was not severe. If a labourer was missing or a machine down, production was brought to a halt. If the weather was severe, the different machines would cause ruts in the ground making it hard for the machines to move around. This was particularly problematic since the tree length logging system requires a network of roads, skidding trails, and landings.
