I bought a craftsman lawn tractor and a pile of attachments but I think I'm missing something to connect the snowblower to the tractor does anyone have schematics or I pic thanks

Think about what you said. It's not answerable.

There will be a Model number on the snow blower attachment. Usually on the top around the discharge chute. I have many PDF files available, but I need to know which unit you have.
