Looks like you had fun. This is what I use if I have to skid logs. It's a boom pole I got from Redland hill. I shortened it to get the load close to the tractor. Back up to the log, wrap the chain around the log and lift and go. The boom replaces the top link, works slick. It would be easy to make something like this for a Cub with a Cat 0 three point.
Edit: Link for the setup that I have.
