Description
The STIHL MS 661 C-M is a high-output professional saw for tough forestry work and thick timber. Its 91.1cc 2-MIX engine makes 5.4kW at a power-to-weight ratio of 1.4kg/kW, so it cuts quickly without being unwieldy. STIHL also uses it as the competition saw in its TIMBERSPORTS series.
M-Tronic electronic engine management keeps performance consistent, and a controlled-delivery oil pump keeps long cutting attachments supplied with oil. This listing is the version with a 63cm (25in) Magnum ES Light bar and 3/8in chain pitch.
