Stihl MS 461
2-Stroke
The Stihl MS 461 is a 76.5cc <!-- verify: stihlusa.com --> 2-stroke professional chainsaw at the top of Stihl's production logging lineup, accepting 20" to 36" guide bars for felling and bucking large-diameter timber daily. The MS 461 uses a 2-MIX engine design for improved fuel efficiency and runs a Walbro carburetor <!-- verify: stihlusa.com -->. At this bar length and displacement, bar groove and nose sprocket wear require close attention — under-maintained bars cause premature sprocket failure. A common choice on Pacific Northwest and Appalachian logging operations.
