Stihl FS-KM – Nylon Head Attachment

The Stihl FS-KM Nylon Head Attachment is more than just a strimmer; it is the most utilized tool in the KombiSystem arsenal, designed to transform your powerhead into a high-performance, straight-shaft brushcutter in seconds. Unlike generic attachments, the FS-KM features a heavy-duty solid steel drive shaft housed within a lightweight aluminum tube ($1.2\text{ kg}$), allowing it to handle the high-torque stresses of professional clearing without the “whipping” vibration found in cable-drive alternatives. Equipped with the AutoCut® C 26-2 head, it offers a low-profile design that allows you to get closer to walls and under low-hanging obstacles than a standard dedicated strimmer. It is the definitive solution for landscapers and large estate owners who need the reach of a straight shaft but the versatility of a multi-tool.

• Solid-Core Drive Shaft Geometry: While many entry-level attachments use a flexible cable, the FS-KM utilizes a solid steel shaft. This provides a direct, unyielding transfer of power from the engine to the head, making it safe and effective for use with metal grass blades (when using the correct guard).

• AutoCut® C 26-2 “Easy-Spool” Technology: Forget disassembling the head to reload. This specific nylon head allows you to thread the line through and wind it from the outside, cutting your downtime in half during heavy clearing.

• Optimized Guard Deflector: The FS-KM comes with a high-impact, wide-angle guard specifically shaped to prevent the “blowback” of wet grass and stones toward the operator—a common issue with narrower, third-party attachments.

• Centimeter-Perfect Balance Point: Engineered to be the “neutral” attachment for the KM-series, the 94 cm length is mathematically balanced to ensure that when used with a harness, the head naturally “floats” $2\text{–}3\text{ cm}$ above the turf.

• Universal Kombi-Lock System: Features a precision-machined coupling sleeve that ensures a dust-proof, airtight connection to your powerhead, preventing the internal splines from stripping over years of commercial use.

• Low-Profile Head for “Ride-Under” Trimming: The C 26-2 head is designed with a flattened base, allowing you to “ride” the head along the ground for a perfectly level finish on lawn edges without scalping the soil.
