A: Hi there! Thank you for your inquiry. Even though both of these products have the same CC engine. Main difference of the unit is that one of them is a low noise unit. The PB-760LNH/T *LN stands for "Low Noise" and has a 65 dB(A) rating and for the PB-770 has a 73 dB(A) rating. There is also difference between the CFM and MPH Speed.

A: To be honest I am not sure. I think it may be that the 760 has a “hip throttle” on the left side and the 770 has a “tube throtle on the blower handle. I have the 760 and it is very nice. The low decibel sound is so nice.
A: This machine has 214 mph.

A: ECHO recommends to use only fresh gasoline with a minimum octane rating of 89 through 93 (mid-grade to premium) at all times. Today's emission certified engines are adjusted leaner and combined with the use of fuel containing 10% ethanol results in higher internal engine temperatures. Use of regular unleaded 87 octane fuel could cause detonation inside the combustion chamber which will result in severe internal engine damage and is not covered by ECHO's product warranty. Using fuels that have an octane rating of 89 or higher will help protect the engine from the harmful effects of detonation.
