Rob,here you go. I stumbled on this from craiglist last year.
It came off a Bx24, almost brand new. I did some research and it was interchangeable for bx25d. Kubota canopy E1133. I like it, it cut my mowing sun time in half. It also may reflect some sound but that doesnt bother me, I'm used to diesels. Its aslo heavy 80-90#, you wont be flipping the ROPS up and down very easily.
