Yes, Poulan, Poulan Pro, Husqvarna, and most Craftsmans except for the past few years are all made by Husqvarna, and use the blade part numbers between all brands.
For example a 138497 blade will be either the 38 or 42 inch blade ( I don't remember which) for the poulan, poulan pro, husqvarna or craftsman 38 or 42"
Now to add some confusion. I am a signed Husqvarna consumer products service center. But cannot warranty Husqvarna named products. Can only warranty Poulan/Poulan Pro.
