I think you're looking for the 47" snowblower (2-stage). This is the same unit used on the 2210, 455, etc. The quick hitch is different but the main blower part is the same. You're looking at ~ $1,000 in parts plus the blower unit (which you can find used if you look).
You can get a 3-pt blower too - but they aren't as convenient (IMHO).
