Jim, always happy to see your posts. Congratulations on the new mower. I don't service small properties like that, but I do understand the concept of using a 21. It is kind of like using my backpack blower, or my handheld. I like the 600 a lot better, but it doesn't make much sense to use it just to blow off a patio. I can sometimes grab the handheld and be done by the time I would get the 600 unloaded and put on.
