The MS 271 FARM BOSS® replaces the mighty MS 270 with a saw that’s loaded with features and technology. It starts with a highly efficient engine that delivers 20% longer run times between refuelings - while cutting exhaust emissions in half compared to the MS 270. There’s also a pre-separation air filtration system that’s so effective, your air filter can last up to five times longer (now that’s high performance). All engineered into one compact, ergonomic design. Features Made in America A majority of STIHL products sold in America are made in America of U.S. and global materials. Pre-Separation Air Filtration System This time-saving technology boosts the efficiency of the engine’s filter system, doubling the time between air filter cleanings. Air drawn into the engine is first separated via centrifugal force, ejecting the heavier dirt particles before being routed to the air filter. This pre-separation means less dirt to be captured by the air filter, resulting in less frequent cleaning and maintenance. Anti-Vibration System 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. 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.
