The Stihl MSA 161 T is a very lightweight, professional 36V battery arborist saw for use in noise-sensitive areas. Thanks to its powerful engine and a chain speed of 16 m/s (40% higher than its predecessor the Stihl MSA 160 T), the Stihl MSA 161 T also accelerates very rapidly and delivers fine, extremely precise cutting. The saw comes with a high-quality ¼” P cutting attachment and captive nut on the sprocket cover as standard.
