STIHL PolyCut 18-2
The STIHL PolyCut 18-2 mowing head is a versatile attachment designed to make trimming and edging tasks more efficient. Equipped with two robust polymer blades, it produces a clean cut with lower noise and vibration compared to traditional line heads. This makes it particularly useful in domestic gardens and residential areas where comfort and quieter operation are important. With its simple, tool-free blade replacement, the PolyCut 18-2 also saves you time on maintenance and keeps your machine ready for use whenever you need it.
Clean cutting performance
The polymer blades provide consistent results when working on medium-height grass and along lawn edges. They extend automatically under load, which ensures smooth cutting without excessive strain on the machine. Because the blades are lighter than standard mowing line, they reduce wear and tear on your trimmer while still offering reliable performance.
Optional line use
For added flexibility, the PolyCut 18-2 can also be filled with 2.4 mm mowing line. This option is ideal when trimming around obstacles or when you need extra reach in awkward spaces. Switching between blades and line makes the head suitable for a wider range of garden tasks.
Compatible with multiple STIHL models
The mowing head can be fitted to several STIHL trimmers and brushcutters, including the FSA 80/R, FSA 90/R, FSA 120/R, FSA 135/R, and the FS-KM KombiTool. This wide compatibility means you can rely on one cutting head across different machines, reducing the need for multiple accessories.
Durable and long-lasting
STIHL recommends soaking new blades in water for 12–24 hours before first use to improve flexibility and extend service life. This small step helps prevent breakage and ensures your mowing head continues to perform well over time. Combined with its sturdy build, the PolyCut 18-2 provides a dependable solution for routine lawn and garden care.
