I just got the info in the mail from CR, and their stuff looks pretty good. Perhaps they can supply the parts you need to get it on your BX. My Simplicity must be one of the very few left side discharge machines, and that makes it tough to find other solutions. I do like the fan powered "turbo 3 bag collector" on my Legacy very much, but it does fill up very fast in leaf season. It is compact, and very easy to install, and remove though, and I could get a 17 bushel wagon for it that is also pretty compact....... The setup is similar to JD's "powerflo", and uses a fan run by one of the mower spindles for added boost.
