Riding Lawn Mowers

I am un the marker of buying a new tractor mower to replace my older GTH2548 unit. I recently purchased a bagger for the older mower a model H348SL. When I purchased the bagger it said it was for a 48 inch mower. I had to modify the installation a little for my older machine. My question is will my bagger model H348SL fit on models other than a 48 inch mower. I've looked at some of the smaller Husqvarna models and it "looks" like it would fit them also. Will it fit?
