01OUTDOOR POWER EQUIPMENT

Secure the blade with precision

The head of a brushcutter is where power meets precision, and this kit ensures that connection remains tight and true. It sits between the shaft and the cutting line or blade, absorbing vibration and holding components in alignment during high-speed rotation.

Designed for Stihl FS55 and a wide range of other models, this six-piece set provides the specific hardware needed to attach various blades securely. It suits homeowners and landscapers who maintain their equipment with care, ensuring reliable performance season after season.
