Maybe you can use something like this, 7th one down on the right

It's the PTO used on a 2284. Thinking you could use this for the blower and your other PTO for your mower. Kind of a PITA to need to swap them but it's an option. You would also need the spacer and the pin that keeps it from spinning. You can find the part numbers on the Cub parts site for those items.
This is the pic of the PTO
