2025 STIHL Chainsaws MS 171

A lightweight, fuel-efficient chainsaw with reduced-emission engine technology.

The STIHL MS 171 is part of the lightweight generation of STIHL chainsaws with reduced – emission technology—a significant benefit for users because it saves fuel even as it cuts exhaust emissions. The MS 171 also has the STIHL pre-separation air filter, which can extend filter life up to five times over previous models.

Features may include:

• A majority of STIHL products sold in America are made in America of U.S. and global materials.

• 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 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.

• Allows operator to easily check fuel level before starting work.
