Unfortunately, along with power comes some noise. Echo has worked hard to reduce the levels by fitting an extra large engine exhaust but on a still day we can hear this one across the road and on the golf course - a distance of around 300m. However, if you need power, this is an astonishing machine - and all for a cost of £409 ex VAT. The testers agrees this is value for money.
This blower shifts a colossal volume of air - up to 1,200cu m/h - and up to a maximum speed of 93m/s. What's more, it's a tough machine - a real commercial unit - and our testers report that it is comfortable to wear.
The PB-755 features an integrated anti-vibration design that provides the user with vibration isolation and results in a vibration figure of just 2.6m/s2 measured at the highest individual axis. The backpack frame features sectionalised padding and simple-to-adjust shoulder straps.
"You can feel this is one of the most powerful blowers on the market," reports one tester. "And, despite its weight, it is comfortable to wear."
The PB-755 is fitted with Echo's Pro-Fire electronic ignition system for easy starting and has a large, two-litre capacity fuel tank to increase operation time between fill-ups.
