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.
