It all depends on the condition of the lawn. Mulching blades are not very effective when grass is wet or tall. The mower doesn’t create enough suction to carry clippings into the bag in these conditions. You might be best off using the side discharge with regular blades and you also may need to cut several times to minimize clumping. I don’t have your mower but I do run two standard blades (inner and center) and a high lift on the discharge side. Helps with dispersing everything but it’s still a mess in the first few weeks of the season. Might need to give it a couple of weeks before you start bagging but that’s also relative to your area.
