I can't tell you the exact model we have, but I can tell you that it's been around forever. When we bought our home in 2002, my dad gave us this mower, it originally belonged to him and he'd owned it for 15 years - we've now owned it for 8 more and she still runs like a champ. The quality behind a Craftsman mower, tool, etc... it amazing. Once a year we take the mower in for a tune-up and that's all the more we've ever had to do. If you take care of a Craftsman, it'll take care of you.
