Gator blades with the side chute or with a mulching kit?Last year my raptor SD with Gator blades would pulverize them pretty quick.
Even if you were to get a bagger I would recommend that you would go over them a few times and get the particle size down quite a bit... you may find if you can stay at them often enough that you don't need a bagger... one nice thing about grinding leaves in the fall as they sure do clean up the underside of the deck nice!
Just the side chute......I keep pushing em towards the street... by the time we get there there isn't much left!
