Snow Blowers

I recently acquired an older Craftsman Yard Tractor (model FF/24) with a snow blower attachment that requires a front-mounted PTO attachment. This PTO attachment was manufactured by American Yard Products, which, as I have learned, was bought out by Husqvarna. My tractor did not come with this PTO attachment and my snow blower is useless without it. Do you have any idea where I can get this PTO attachment (model number 917.263091) or one that would work in its place? Thank you for your help.
