I can't tell you all the part numbers, however, you will need a quick hitch and a drive kit to go with the quick hitch, and a driveshaft to hook that up to your tractor. In theory, the hitch will fit from the original BX series starting around 2003 up to and including the new BX80 series starting in 2017 to the present. The only thing that I can see as a problem, is that with that quick hitch, it will not be possible to open the hood on the BX80 series tractors. I have no experience with the BX24 or 25 tractors, so I can't comment on those. Most times you don't find the quick hitch separately but are sold as part of a unit. That hitch was also used with the plow, less the driveline kit, and shaft.
The snowblower will fit a K-Connect system on a BX 80 series if you change out the mounting system for the K-Connect mounting and replace the internally splined drive connector for the drive for the K-Connect drive part. My guess is those parts alone will cost you $350-$400 unless you can find them used. I doubt that the dealers will tell you this information since they want to sell new equipment, rather than parts to complete a conversion from the old to the new.
If I can find the time, I will post some pictures of the parts that were removed from a BX 80 series snowblower, and replaced with the older parts from a 15-year-old snowblower.
