Echo PB-755ST vs PB-580T - The Differences
Feel, Fuel & Noise
As the PB-580T and the PB-755ST are both Echo blowers, they benefit from the same level of quality and attention to detail.
- Designed as backpack blowers, both products boast substantial engines and sizable fuel tanks, making them easy to carry for extended periods. You'll find the throttle positioned on the tube of both products, ensuring that your left hand remains unoccupied for other activities.
- gas-powered blowers, both products offer a dependable power source that can be refilled quickly, allowing you the mobility to cover extensive outdoor spaces without interruption.
- The Echo PB-755ST, weighing 24.7 lbs, edges above the Echo PB-580T's 22.7 lbs, which may give the lighter unit a slight advantage in comfort and fatigue.
- The Echo PB-755ST 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
- When compared, the Echo PB-755ST demonstrates a CFM of 651, surpassing the 517 CFM of the Echo PB-580T, establishing it as the more powerful tool for swiftly clearing leaves from your yard.
- The Echo PB-755ST with an MPH of 233 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-755ST features a slightly larger fuel tank, with a capacity of 67.6 fl.oz., potentially allowing for longer operational periods, provided its engine is as fuel-efficient as that of the Echo PB-580T.
- When comparing engine displacements, the 63.3-cc engine of the Echo PB-755ST edges out the 58.2-cc engine of the Echo PB-580T. This indicates a potential slight increase in fuel consumption per stroke and a corresponding bump in power output. Both of these leaf blowers are equipped with 2-stroke engines, meaning they require an oil/fuel mix for operation.
Other features
- Neither the Echo PB-580T nor the Echo PB-755ST has the ability to vacuum leaves. Thus, you will require another method of leaf collection.

I have a 580 and upgraded this weekend to a PB755ST this weekend.
I prefer the 580 for several reasons. The biggest difference is the flexible blower tube is longer- this puts a lot more pressure on my arm, my arm is extended the entire time. The 580 is shorter and I am able to use my body to support the blowing. The two you noted, noise level and heavier. You would think 2 lbs is not a lot, however it feels like the weight is not equally balanced, the weight is heavier on the left side.
Also, a couple other small things that are made and better quality for the 580. 1) The shoulder pads are wider and thicker, better support and 2) the Air intake cover is cheap flimsy plastic, that I can smell when heated. The 580 is better quality and no smell.
I am curious if anyone else experienced these differences.
