Talk about legendary. If there are large trees that must be felled, more than likely, this is the saw that gets the nod. The MS 660’s amazing power-to-weight ratio gives you a whole lot more power (a 15% increase in engine power over the MS 460!) with only a marginal increase in weight. Small wonder, then, that it’s been the chain saw of choice for so many professionals, and the saw chosen for use in the STIHL® TIMBERSPORTS® Series.
STIHL has developed a system for minimizing the vibration levels of handheld outdoor power equipment. The STIHL anti-vibration system helps reduce operator fatigue and provides a more comfortable working experience.
The Winter/Summer Shutter allows the carburetor to operate at optimum temperature year-round and helps to prevent carburetor icing when working below 50F (10C).
Side-Access Chain Tensioner
The side-access chain tensioner makes it much more convenient for the user to adjust the saw chain with a bar wrench as opposed to the typical location of the guide bar adjustment screw.
