I recently tried to buy gator blades for one of my mowers when I was disappointed to learn that none are made that fit it. My plan was to be able to bag leaves when I wanted and also to mulch when I wanted without having to change blades or install mulching baffles. So my question is are split-level style mulching blades useless without the baffles installed? Would I be better off with the factory blades? The only time I'd be running this set up is for leaf clean ups. Thanks for any input you guys can give.
