Welcome to the forum.
Mulching is a process where the blades cut the grass into smaller particles with the addition of additional "teeth" on the wing side of the blade. Then these smaller grass particles drop into the grass surface where they are much easier to decompose. The use with a bagger would mean that since the grass particles are smaller, you can fill the bag(s) with more.
Many of the mulch kits include some type of baffle under the deck to facilitate the cutting of the grass clippings several times and attempt to drop the clippings to the ground. For some, the mulch baffles work and for others they don't.
People sometimes change the regular blades for mulching type blades in the Fall for use with getting the fallen leaves.
I mulch mow year round without the use of baffles and only plug the discharge so all they clippings fall to the ground. I also use Gator blades.
Hello stevehw View attachment 2456134 I think the use of mulch blades is a personal preference, and that preference is a result of trying them...some guys swear by them.....guys like me are satisfied with regular blades and don't bother with them...it won't hurt to have them on hand for when you do need a new set and give them a literal whirl...good luck with the new machine
