Sorry Langanbob - I haven't checked this forum in a while.
The mount is referred to as the Quick-Hitch subframe. It has a lift cylinder, hoses and a mid PTO shaft.
Looks like this:

Front implements, Snow blower, Rotary Broom, Blade all have a female receiver:

I got the sub frame, minus the mid PTO Shaft, when I bought my MF 2330 Rotary Broom
The Mid PTO Shaft was a bit difficult to locate at the time. (I was able to order it from Jack's Small Engines)
The same Canadian company makes the Subframe, Snow Blowers, and Rotary Brooms for Red, Orange, and Blue tractors.
The Red Massey Blower is MF2360 (older design)
The Orange is BX5450 (new design)
and The Blue is 50CS (new design)
All are 50" snow blowers and are interchangeable tho I've been told there is a slight difference in Mid PTO rpm's and so the gearing of the chain driven augers are slightly different.
While that may very well be true, my Orange Blower mounted on my Red tractor does a fine job now in it's 3rd year.
What you are looking at in a New Holland 63CS is.... a 63" Blower which is not made to function on a 22-25hp subcompact tractor.
