The saw chain matters
The aim of the study was to identify any differences in basic cutting capacity and energy consumption between the most common saw chain models on the market. Another aim was to examine whether sharpening brand new chains would have any effect on cutting time and energy consumption. All trials were carried out on the test rig built up at Skogforsk in Sävar.
The results revealed that the brand new chains varied by approximately 6% in terms of cutting time and energy consumption. The resharpened chain had a shorter cutting time (9%) and lower energy consumption (10%) than corresponding brand new chains. All these differences were statistically reliable with a very high degree of certainty.
