I just purchased a bagger for my Cub Cadet LT1046. I have a question regarding the blades that came with the bagger. Do the blades that came with the bagger need to be installed for the mower to push the grass through the tube to the bagger? I using the mulching blades that came with the mower. However, every time I mow the lawn the grass gets clogged in the tube before it reaches the bags..... Am I doing something wrong here? The grass is dry and not wet.
