I Think Its Just A "beter" Way Of Selling.they Just Seem To Make Them Alittle Beter Sounding. Just Look At The Poulan Site. Poulan Are The Smaller Sizes And Were Labeled Poulan Pro. Craftsman Does That To. Last Winter I Was Looking At Blowers And They Were All Plane Craftsman Except The Two Largest "profasional".
Yeah, it's pretty much the paint, although there MAY be an extra feature or two. My Craftsman Professional has almost identical specs to the DYS4500 except for an ELS engine, an amp meter, a bumper and electric PTO.
