The STIHL MS 661 C-M R professional chainsaw is a real powerhouse, offering strong and consist performance ideal for forestry work. It combines cutting-edge technology with an optimal power-to-weight ratio of 1.4 kg/kW and is ideally suited to particularly tough and demanding forestry applications. The gas chainsaw can process even hard wood effectively and quickly. The chainsaw is powered by a 5.4 kW (7.3 hp) STIHL 2-MIX engine, which ensures constant high performance thanks to STIHL M-Tronic. The controlled-delivery oil pump reliably supplies the cutting attachment with oil and facilitates the use of long and very long cutting attachments.
