I'm fixing to get a new 21". I do not want self-propelled. I will mainly mulch, but once in a while bag clippings. Also, some side discharge. Both are at the same dealer and bot are $300. Snapper with side discharge, ninja mulch kit and Briggs 6.75hp. Or Lawnboy with Honda engine(doesn't specify hp) side discharge, and bagger. Bag is extra with Snapper. I will say I like the idea if Honda engine, but I do like the wheel/axle design on the Snapper. I will be using this about 6 hours a week on level lawns. Some Bermuda and some fescue.
