professional chainsaw with enhanced fuel efficiency and STIHL M-Tronic™ technology
The STIHL MS 661 C-M professional chainsaw is a real powerhouse, offering strong and consistent performance. It combines cutting-edge technology with an optimum power-to-weight ratio of 1.4 kg/kW and is ideal for particularly tough and demanding forestry applications. Even thick wood can be processed effectively and quickly using this petrol-driven chainsaw.
The chainsaw is powered by a 5.4 kW (7.3 hp) STIHL 2-MIX engine, which ensures a consistently high performance thanks to STIHL M-Tronic. The controlled-delivery oil pump reliably supplies the cutting attachment with oil and enables the use of long and very long cutting attachments.
The STIHL MS 661 C-M petrol-driven chainsaw is also used as a competition saw in the STIHL TIMBERSPORTS® series. Other features of the STIHL MS 661 C-M chainsaw:
- the HD2 air filter removes even the finest dust from the air, and is easy to clean using STIHL VarioClean. In a video guide, we demonstrate the cleaning process.
- The STIHL anti-vibration system enables you to work comfortably and protects your muscles and joints.
Tool-free fuel caps save you time and effort when filling the chainsaw.
