I see there are a lot more people than I first thought using primarily 21" mowers. I am in the same boat, and wanted to see what kind of blades everyone was using? I see all kinds of stuff on Meg-Mo's and Gators etc. and wondered if anyone has a prefernece on blades and the 21", or if they found it didn't much matter. Thanks for any input in advance. I'm using Toro's stock blade for the time being, but will probably be experimenting in the next month with all the leaves.
