Overview of the Echo PB-770T
- Power: The PB-770T, built by Echo, is a gas-powered leaf blower capable of expelling a maximum air volume of 756 cubic feet per minute (CFM). Its air speed is rated at 234 MPH.
- Handling: Like most backpack blowers, this model is technically heavier than a handheld. That being said, it can feel lighter and more comfortable because of the way it is carried, even when used over extended periods of time. Its throttle is located on the tube, which allows you to keep your left hand free. However, for a gas-powered backpack blower, the Echo PB-770T is heavier than most, weighing 24.3 lbs.
- Engine: The engine boasts a displacement of 63.3cc. Since this is a 2-stroke engine, it’s important to remember that the PB-770T cannot run on gasoline alone. The fuel must be mixed with an appropriate ratio of gasoline and oil in order for it to function properly (for this Echo model, this ratio is 50:1).
- Speed Settings: With its variable speed settings, the Echo PB-770T allows you to precisely control its air output. In addition, the blower is also equipped with cruise control, with which the user can easily maintain the selected settings.
- Noise: Its noise rating of 74 dB can be considered the standard for similar gas-powered backpack blowers.
- Fuel Tank: With a capacity of 68.3 fl. oz., this Echo blower is average compared to other gas backpack blowers.
