The STIHL MS 661 C-M is a high-performance professional chainsaw built for the most demanding forestry and timber harvesting tasks. With a powerful 5.4 kW (7.3 hp) 2-MIX engine, advanced M-Tronic™ technology, and a power-to-weight ratio of 1.4 kg/kW, this saw delivers exceptional cutting performance, even through thick wood. Its robust design, low vibration levels, and long-life components make it a trusted tool for both field professionals and STIHL TIMBERSPORTS® competitors.

Built for Heavy-Duty Forestry Work: Designed for felling and processing thick timber, this chainsaw delivers consistent power and torque in the toughest conditions.

Powerful 2-MIX Engine: The 5.4 kW engine offers high output with low emissions and fuel consumption, keeping performance strong and sustainable.

Smart Engine Management with M-Tronic™: Automatically adjusts fuel delivery for easy starting and optimal performance, no matter the environment or workload.

Optimised for Long Cutting Attachments: The controlled-delivery oil pump ensures reliable lubrication, even when using long or extra-long guide bars.

Advanced Air Filtration System: The HD2 filter with radial seal and pre-separation routing system protect the engine from fine dust, helping to extend run time and reduce maintenance. The filter can be washed using STIHL VarioClean, so frequent replacements are not required.

Comfortable Operation with Anti-Vibration System: Reduces strain on muscles and joints, allowing for longer, more comfortable use in the field.

Quick Refuelling with Tool-Free Caps: Save time with easy-access fuel and oil caps, designed for fast, tool-free filling.

Features

Features

2-MIX Engine

Modern, powerful and economical engine. Provides fuel savings and reduced emissions.
Anti-vibration System

Vibrations from power tools can lead to negative effects on blood vessels. STIHL has developed a system for minimizing the levels. This also helps reduce operator fatigue and provides a more comfortable working experience.

Ematic Chain Lubrication System

A reservoir holds bar oil until it is picked up by the passing chain. This achieves maximum lubrication resulting in longer wear and less oil consumption.
Single Master Control Lever

All the important functions of start, choke, throttle and stop are operated via a single lever.

Easy Open Fuel and Oil Tanks

Special caps on the fuel and oil tanks allow for easy opening and re-fueling.
HD2 Filter

This air filter keeps even the finest dust away from the engine, which increases the service life of the engine. The HD2 filter element is made from a robust long life material that can be washed repeatedly. For best results we recommend the use of STIHL Varioclean and warm water.

STIHL M-Tronic™ System

The STIHL M-Tronic™ system electronically manages the air/fuel and ignition requirements of the saw. Ensuring optimal performance in all operating conditions. This technology also provides a simplified starting procedure.
STIHL ElastoStart

A spring or rubber element in the starter handle is used to balance out the peck compression resistance when pulling the starter cord. This reduces the perceived starting effort by up to 30%.

Side Chain Tensioner

There is a tensioning screw on the side of the Chainsaw through the sprocket cover. This is easy to use and removes the need for contact with the sharp saw chain.
Controlled-delivery Oil Pump

Different bar lengths, wood types and sawing techniques require different amounts of oil. The controlled-delivery oil pump allows the user to select just the right amount of oil for the job.

Decompression Valve

The decompression valve, vents compression in the cylinder to reduce the cranking effort.
