ACTIVE ST37BT BRUTALE STRATO Fixed-rod brushcutter Technical data Displacement: 30.8 cc Power: 2.2 Hp - 1.6 kW Rod diameter: 26 mm Clutch diameter: 62 mm Tank capacity: 0.6 L Weight: 6 kg STRATO CHARGED BRUTALE Extremely low pollutant emissions up to 80% reduction in HC from 40,000 ppm to 8,000 ppm. Significant increase in torque and power (up to +30%). Considerable reduction in fuel consumption (up to -20%). The significant amount of clean air that enters from the outside through the two separate intake ports and is accumulated in the cylinder racks favours the engine's scavenging phases, which therefore take place with fresh air. All this guarantees a drastic reduction - up to 80% - of HC (unburned hydrocarbons) at the outlet. ENGINE OVERHEAD COMPONENTS Magnesium alloy engine casing to reduce weight by 30%. CYLINDER Aluminium alloy cylinder with STRATO-CHARGED technology. PAPER FILTER Oversized paper filter for greater autonomy before cleaning.
