I'm not sure if you're looking for a front or rear mounted snowblower.
If it's a front you'll need the subframe quick attach assembly plus the mid-pto driveline kit. With this option, you can go with either the BX2750D (50") or B2781A (51" - more heavy duty) snowblowers.
For the rear 3-point Hitch, Kubota offers a B2789 51" snowblower. Obviously, there's a number of other options/brands as well for 3PH snowblowers.
