STIHL MS 400 C-M Gas Chainsaw, 20" Bar (Lightweight), 33 RS3 Chain

Built for demanding tree care and forestry work, the STIHL MS 400 C-M delivers serious professional cutting performance without added weight. Its advanced magnesium piston provides greater displacement, power, and torque than aluminum piston-equipped counterparts, giving professionals the strength to take on tough cutting jobs in a well-balanced package.

STIHL M-Tronic™ engine technology automatically adjusts to changing operating conditions, helping maintain fuel-efficient, low exhaust emission performance throughout the workday. When the work doesn’t let up, the MS 400 C-M is designed to keep downtime to a minimum. A pre-separation system removes larger debris before it reaches the air filter, extending the time between cleanings, while the long-life HD2 air filter can be cleaned instead of replaced.

With intelligent engine management, purposeful weight savings, and an air filtration system built for longer run times, the MS 400 C-M gives tree care and forestry professionals the performance they need to keep demanding work moving.
