It is a Huskey 570BTS. I sold my old redmax 7150 and decided to get the Husky instead of the Redmax 7150. I like the harness with wait band better on the Husky. I was thinking just fuel it and go, but you hear about holding back on full throttle continously untill you have run 2 or 3 tanks of gas. This is my 1st new backpack in several years.
