Well, you CAN pull a disk. We all disked with far less tractor than that in the 50's and 60's. Back then we had draw bar disks, likely 6' in size, two rows. I spent many, many an hour pulling disks for my dad, grandpa and uncles on our farms. Most of it on some pretty heavy clay, but remember that ground had already been plowed the previous fall or spring.
The trick is to find a solid disk, new (hate to say it, but at TSC and similar, they have the XB stuff which is in your wheelhouse) or scour the eBay, Craigs listings until you find an used older disk that fits. Don't try to pull some 8' disk. You can find a 5 or 6 footer that will do you fine. Expect to spend time going over it and over it though. Best wishes in your search.
