Cutting
Updated design for increased capacity
In connection with the transition from 100 to 100S, we have changed from a 10 mm bar groove to a 15 mm groove. As a result, the frame and saw box on the 461 LF NG have been extended compared to the previous model.
The updated design is adapted to enable the use of a 67 cm guide bar with a 15 mm groove, providing increased flexibility in guide bar length selection. The result is a clear performance improvement: the maximum cutting diameter increases from 53 cm to 59 cm.
