STIHL MS 400 C-M – Lightweight Power, Unmatched Performance
Engineered for the most demanding forest and tree-care professionals, the MS 400 C-M stands out as the world’s first professional chainsaw to incorporate a magnesium-alloy piston. This breakthrough delivers greater displacement, torque, and power—all without adding weight—resulting in an exceptional power-to-weight ratio (approximately 12.8 lbs / 5.4 bhp) with a lightweight, modern design.
Key Features
