STIHL MS 400.1 C-M: The Professional 60cc Benchmark

The STIHL MS 400.1 C-M is a ground-up redevelopment designed to dominate the mid-range forestry class, replacing previous models with an industry-leading power-to-weight ratio of 1.41 kg/kW. Delivering 3.9 kW (5.3 hp) from a refined 62.6 cc 2-MIX engine, this powerhead weighs a mere 5.5 kg—shaving 300g off its predecessor while boosting peak torque output to 4.3 Nm. Engineered for high-demand felling, snedding, and commercial cross-cutting, the saw maintains smooth cutting speeds under heavy load without bogging down. Equipped with the latest M-Tronic 3.0 electronic engine management, an upgraded high-capacity HD2 air filtration system, and a larger magnesium flywheel for maximum thermal cooling, the MS 400.1 C-M gives arborists and forestry professionals absolute reliability and rapid acceleration through long daily shifts.

• Market-Leading 1.41 kg/kW Power Density: At just 5.5 kg dry weight, the re-engineered 62.6 cc engine achieves unprecedented power-to-weight efficiency in the pro 60cc forestry segment, minimizing user fatigue during all-day canopy work.

• 4.3 Nm Sustained Torque Engine Tuning: Delivers higher low-end pull and reduced pressure sensitivity mid-cut, enabling smooth plunge-cutting and felling of large-diameter timber without engine stalls.

• M-Tronic 3.0 Fully Electronic Engine Management: Automatically adjusts ignition timing and fuel metering based on altitude, temperature, and fuel quality, delivering instant throttle response and effortless starting with no manual carburetor adjustments.

• Thermal-Optimized Magnesium Flywheel & Exhaust Architecture: Features a larger magnesium cooling fan wheel and redesigned muffler casing that actively pulls heat away from the cylinder unit during heavy duty cycles.

• Contoured Trunk-Glide Underside: The bottom of the crankcase incorporates an optimized ribbed structural pattern designed to slide effortlessly along logs during delimbing, reducing snagging on bark.

• Tool-Free External Flow-Adjustable Oil Pump: Features top-accessible oil flow regulation that operators can adjust in seconds on site using a standard combination wrench.

• Extended-Surface HD2 Air Filtration: Heavy-duty radial air filter with a pre-separation system captures fine dust and wood particles, keeping the intake clear to extend service intervals and lower engine wear.
