I found a couple of Snapper 28" mulch kits on E-bay and bought them. The kits had the "Ninja" blades they are a multi cutting surface blade,dull fast and are expensive($40+) I like the Gator blade, it's cheaper, cuts longer and dulls less often it's an all purpose blade ,vacuuming, mulching and discharge mowing.Having said that.the Ninja mulches a little better(while it's sharp) the hi-lift vacuums better ,but the Gator does it all.
