Well, actually Husqvarna currently owns the company, and they build mowers that say Craftsman on them. In addition to Poulan, Weed Eater and many other names.
Before that it was Electrolux and before that it was Roper and AYP.
I work in a dealership that sells Husqvarna products. Their push mowers are not particularly troublesome. At least not as long as the customer keeps good fresh gas in them.
