My friend, who is also an LCO is all the time telling me that his BR400 blower is just as powerful as my BR600 and he can't understand why anyone would buy a BR600. Well, at the end of the day today another LCO friend of mine stops by the house and shows me his new Echo PB755 blower. My friend with the BR400 shows up too. I ask to see what the PB755 will do and we have a little contest trying to blow a pressure treated 4x4 (3ft in length) across the driveway. The PB755 rolls it down the cement about 6 ft. I fire up the BR600 and it tumbles about 7 - 8 ft. My friend with the BR 400 claims that it'll do the same thing. He fires it up and it won't even budge the 4x4. We all had a good laugh and told my friend that we don't want to hear him anymore bragging about his "big powerful BR400"
