Yes very little on it due to its age.

There are manuals for the C950 series.

That doesn't look like quite the right model number for a Craftsman blower. I have not seen any in that format. They are typically all numbers and have a period after the first 3 digits, such as "536.90560"
I would take another look and see if you can find a tag that has a model number like that. It should be on the same tag as the serial number as well. If you are able to find that, you can visit http://www.searspartsdirect.com/ and put the number and specify "model number" and search. They will likely have the manual.

Sears online tech manuals.

Here is the operator's manual for your mower. http://www.managemylife.com/mmh/owner_manuals/14328/CRAFTSMAN-Lawn-Tractor-L0911505?brand_name_search=917.289101
Page 22-24 shows you how to remove the mower. You will need the manual for the snowblower to mount it to the tractor.
If you don't have the manual for the snowblower go to managemylife.com. Under the manuals tab put in the model number of the snowblower (you will find it on the snowblower and it looks like 123.123456)
You can view, download, and print the manual there.
It is a pretty big job. It will take you about 5 minutes to remove the mower and about 3 hours to mount the snowblower.
Let me know what other questions you may have.

Ok
That Snowblower is made by Agri- Fab for Sears/Craftsman .If you go online to the agri-Fab website it is possible to down load the manual or if you email them they will send you a copy. I have dealt with them.They have even sent me missing parts. GOOD LUCK
