Stihl FS 55

2-Stroke · Also known as: FS 55 R, FS 55 RC

The Stihl FS 55 is a 27.2cc <!-- verify: stihlusa.com --> 2-stroke trimmer available in curved and straight shaft configurations, bridging Stihl's homeowner and prosumer ranges. The straight-shaft FS 55 R variant is popular on landscaping crews for its reach and versatility. The FS 55 accepts a wider range of accessory heads than the FS 38/40/45 and can operate brush blade attachments. It runs a Zama carburetor. At this intensity of use, seasonal fuel system and air filter maintenance is the minimum; the commercial straight-shaft variant warrants monthly inspection. Often a homeowner's first straight-shaft trimmer.
