Dixie Chopper's giant sized discharge doesn't really lend it's self well to bagging. The discharge blade is also set in about 4 to 5 inches from the edge of the deck and it makes for some really lazy air there. There have been several users here at Lawnsite that have tried powered baggers in the past and it just didn't work out for them. Cut a few inches off of the discharge and it should work fine.
