Mulching blades are just low or ultra low lift blades. Gator cuts voids in the lift portion to reduce lift and also "CLAIM" to bag perfectly. Notice the tiny lip on those Gravely blades = mulchers.
Mulching also chokes the turf from air, water and fertilizer. Lots of spring and early summer rains can lead to turf disease and your turf growing mushrooms. Bagging has always been the best looking mow method by far.
This is the other extreme of mulching blades. Snapper did this many decades ago. Still haven't seen another mower company try to duplicate this. Course 99% of us fat lazy Americans tend to mulch or sling.
