The 550UX is a premium quality brushcutter / clearing saw, with a full, professional-quality, anti-vibration system. The Soft Start system and Auto-On Ignition, combined with the Auto-Choke system, mean that, although the 550UX is our most powerful brushcutter, it is just as easy as the 450UX to start - with minimal effort. The extra-low vibration levels, easy starting and premium quality, fully padded harness, make this model comfortable and easy to use - even for a whole day’s work.
