The aim of the study is to evaluate productivity and potential reduction greenhouse gas (GHG) emissions due use compact class Malwa harvester 560H forwarder 560F in thinning aspen hybrid plantations as well indicate production cost analyse possibility forest machines this definite quality thinning, including damage remaining trees, width strip-roads, provide recommendations for further development technology.These parameters have significant effect on productivity, fuel consumption vitality trees.The are affected by tree dimensions, if average harvested stem diameter 12.2 cm, 8.63 m 3 per productive hour harvesting 12.24 EUR•m -3 , but gives a big impact -10.96m -10.04EUR•m .The load 4.03 forwarding 5.1 total -21.04EUR•m .Harvesting related GHG 4.12 kg CO2•m -49% -51%.According results using significantly smaller than middle-class high values; besides, maintenance investment costs smaller.The mechanical roots stems trees during logging inevitable.This ensured recommended working methods setting special attention felling direction distance between stand, avoiding unnecessary movements with manipulator.
