Well I gave in to my wife and bought a bagger for my bx24. After I installed it I ended up with an extra part so I decided to read the instructions. This 3/16" thick x 6" wide x 19" long orange part is no where to be found on the instructions. I spoke to a dealer and he thinks that it is a deflector which would help the collection system work better. It has 2 square holes for carraige bolts and a 4" long arm on it. I can"t find anywhere on the deck that will accept it. Anyone help would be appreciated Thanks, Keith
