I got a couple P.M's about some posts about back pack blowers. Husqvarna's 170 and 180 back pack blowers are Redmax units. They purchased Redmax over a year ago. The 170 has been out for a while the the 180's are out now, they started shipping a couple weeks ago. Differences are the Husky has a heavier duty molding on the frame, better padding and straps, different plastic engine shround, and a different tube handle, and they give you 1 more tube to go out the blower tube. There has been some rumors going back and forth about this and no, it's not a tall tale. They are Redmax EBZ7001, and EBZ8000 blowers. I can post pictures anyone is curious. Redmax equipment will start coming through with new decals that say "Redmax by Husqvaran" at some point, or so i've been told.
