Yes I know their have been threads about Redmax 8000 but didn't see any about grass on concrete. I know several of you have had the REDMAX 8000 for some time now. Thinking about buying a used one so here are my questions. 1. I got an ECHO pb-200 handheld now. It takes forever to blow off damp/wet grass in the morning off concrete. How does the 8000 do in this situation? Does it blow off all the grass in one pass or do you have to keep moving the blower tube back and forth several times to get most or all the grass off the concrete? 2. Have you had any problems with yours? 3. Do you get used to the weight of the blower on your back?
