MS 661 C-M STIHL Pro Saw – Ultimate Power for Extreme Cutting Performance

When you need extreme power, professional-grade performance, and maximum reliability, look no further than the MS 661 C-M STIHL Pro Saw. Engineered for the most demanding forestry professionals, this high-performance chainsaw is purpose-built for heavy-duty felling, bucking, and large-scale wood cutting tasks in rugged environments.

At the heart of the MS 661 C-M is a 91.1 cc STIHL 2-MIX engine, delivering a jaw-dropping amount of torque with reduced fuel consumption and emissions. Despite its massive power output, this saw remains efficient and environmentally conscious—making it the ultimate solution for productivity without compromise.

What truly elevates this saw into a league of its own is the inclusion of STIHL’s M-Tronic™ engine management system. This smart technology continuously monitors and adjusts the fuel mixture based on altitude, temperature, and engine load—ensuring flawless throttle response, reliable starting, and peak performance in any working condition. There’s no need for manual tuning. Just start it and get to work—every time.

Whether you’re felling massive hardwoods or working long shifts in the forest, the MS 661 C-M Pro Saw is built to go the distance. With its anti-vibration system, ergonomic handle design, and well-balanced body, this saw reduces operator fatigue and enhances cutting precision—even during all-day operations.

Engine longevity and easy maintenance are built into its core. The HD2 air filtration system captures fine dust and debris before it reaches the engine, dramatically extending filter life and reducing downtime. Combined with tool-free fuel and oil caps, servicing your saw in the field is fast, clean, and convenient.

The MS 661 C-M isn’t just a powerhouse—it’s a battle-tested tool of the trade, trusted by logging crews and forestry professionals worldwide. Its magnesium crankcase and high-strength components are designed to withstand extreme use and harsh environments, job after job, year after year.

If your work demands nothing short of top-tier power, intelligent performance, and rock-solid reliability, the MS 661 C-M is built for you. It’s a saw that doesn’t flinch under pressure—it thrives in it.
