    Easy to start

    The unique design of the carburetor, cylinder, and digital ignition system, together with the air purge and decompression valve, ensure an easy start.

    Maintenance-free air filter

    The only time the filter needs to be checked and changed is if you experience a lack of power.

    High power with less fuel

    Our built-in automatic filter compensation SmartCarb™ maintains high power and lowers fuel consumption.

    Optimized engine performance

    Optimized engine performance through efficient cylinder design, digital ignition system, and X-Torq® engine technology.

    Less slurry and low water consumption

    Excellent dust control with our wet-cutting kit. A progressive water valve for exact adjustment of the water volume to efficiently bind the dust and reduce slurry.

    Easy to change blade guard position

    The light magnesium blade guard facilitates cutting, thanks to its step-less adjustment.

    Fits multiple-blade bushings

    Blades with 20mm and 25.4mm bores can be fitted thanks to the reversible blade bushing.

    Fewer emissions and fuel consumption

    Our X-Torq® engine produces fewer emissions, has lower fuel consumption, and results in more power.

    Blade Shaft And Bearings

    Provide extended blade life and reduces maintenance.

    Maintenance-free starter

    Patented, dust-sealed starter unit with a sealed return spring and pulley bearing. DuraStarter™ also includes a starter cord with greatly increased durability. This makes the starter virtually maintenance-free, further enhancing the reliability of our cutters.

    Reduced wear

    Reduced wear thanks to the drive belt with a fully sealed transmission, which keeps out the cutting dust.

    Cuts close to walls or ground

    The cutting arm is reversible which lets you cut closer to walls or the ground. The drive belt has a fully sealed transmission. This keeps out cutting dust etc, reducing wear.

    Active Air Filtration™

    Our two-step filtration system with centrifugal cleaning and a single paper filter increases product life and extends service intervals.

    Anti-vibration system

    Our anti-vibration system reduces vibrations in the cutter handles, so they are more comfortable to hold and can be used for longer periods. To provide the user with a comfortable operating position and reduced strain, the distance between the handles is large. The handles and the short engine body mean the user always stands close to the machine, for easier handling and control.
