Echo PB-770 63.3cc Petrol Backpack Blower
The PB-770 is in a different category to the compact backpack blowers — this is a serious professional machine built for heavy-duty clearance work where output volume and air speed are what matter. The 63.3cc engine producing 3.1kW generates 1,290m³/h airflow at 104.6 m/sec, numbers that put it among the most powerful backpack blowers available for professional landscaping use.
At that level of output, wet leaves, compacted debris, gravel, and material that would barely move under a lighter blower gets shifted quickly and efficiently. The 2,020ml fuel tank is sized to match — providing extended runtime that keeps up with the machine's capability on large sites without constant refuelling stops.
At 11.0kg it's a substantial machine, but the ergonomic design with ventilated back pad distributes the weight comfortably across the shoulders, and the anti-vibration technology keeps the vibration levels remarkably low at 2.8 m/s² — exceptional for a machine of this power. Intuitive controls are easy to access without removing the blower, and the heavy-duty air filter protects the engine in the dusty conditions that come with intensive clearance work.
