The Stihl MS 171 is a light gas chainsaw with a 16-inch bar, built for occasional yard work rather than daily felling. Its reduced-emission engine and pre-separation air filter, which Stihl says can last up to five times longer between cleanings, set it apart from older budget saws. It suits homeowners cutting firewood, clearing storm limbs and trimming around a property. Against the MS 170 it replaces, it adds the improved filter and cleaner running; against larger farm saws it gives up power and bar length.
