re: Anyone ever owned/used a 30 inch push mower?

A 28" or 30" Snapper rear engine rider will take up about the same amount of space in your garage. You can get a good to great condition used one for $400-800 on FB Marketplace. Used is the only option since they don't make them anymore. Simple easy mower to fix or maintain with plenty of parts available. You can stand them up on the end to take up less space in the off season.
