Feel, Fuel & Noise

As the PB-580T and the PB-770T are both Echo blowers, they benefit from the same level of quality and attention to detail.

These two products are constructed as backpack blowers, allowing you to comfortably carry their big engines and massive fuel tanks. Both products have their throttle located on the tube of the blower, which allows you to keep your left hand free.
Both products are gas-powered blowers, providing a reliable power source that can be refilled in seconds, granting you the flexibility to navigate through expansive outdoor areas effortlessly.
With 24.3 lbs versus 22.7 lbs, the Echo PB-770T is only marginally heavier, and the small gap in weight is unlikely to make a noticeable difference in fatigue or maneuverability.
The Echo PB-770T registers a noise rating of 74 dB, slightly above the 70 dB rating of the Echo PB-580T. Opting for the Echo PB-580T could result in a quieter experience for both you and your neighbors.

CFM & MPH

The Echo PB-770T, providing a CFM of 756, outmatches the 517 CFM of the Echo PB-580T. Your leaf blowing experience will therefore be outstandingly improved with the Echo PB-770T, as it should be able to move considerably more leaves per minute.
The Echo PB-770T with an MPH of 234 slightly exceeds the 216 MPH of the Echo PB-580T. Thus, in comparison, the former expels air at a slightly higher speed, and should do a better job at blowing leaves on grass or lifting wet leaves and debris (acorns, etc.).

Engine specs

The Echo PB-770T's larger fuel tank, holding 68.3 fl.oz., has the potential to provide longer usage periods, assuming similar engine efficiency to the Echo PB-580T.
In contrast, the Echo PB-580T's engine, with a displacement of 58.2 cc, is slightly surpassed by the 63.3-cc engine of the Echo PB-770T. As a result, the latter may consume marginally more fuel per stroke, potentially resulting in a slight power advantage. With 2-stroke engines, both leaf blowers mandate an oil/fuel mix as part of their operation.
