If as Working on Rust has suggested you do not have live pto, then I would suggest you start looking for an inverted or pull type blower.
Here is mine installed on a 2wd Nuffield 465.
It is a single auger two stage unit made by Smyth Welding in Canada.
Previously I had a conventional style rear facing blower but the Nuffield reverse gear was far too fast and even though I had live pto I was having to slip the clutch or hold the tractor back with one rear brake so that the blower could manage the snow.
Next I found a very rare low reverse gear for the Nuffield and installed it but it was still too fast.
With the inverted or drag behind blower I have all five gears of the transmission plus the two ranges (high and low) so I can have the tractor traveling at a speed through the snow that the blower can handle.
This type of blower has been around for a few years and used ones do come up,
The rear blade is my addition although it is also a factory option.
It allows you to back up to a garage door, drop the blade and pull the snow forward. Then you back up and run the snow pile through the blower.
This style of blower and rear blade is very popular with people cleaning residential driveways.
My lane is 100 meters long in gravel and I also clean a mile of trails over grass. Much easier on the neck as well.
