That's about what I was thinking. I was going to make a flange a while back just for storage but that won't work with the cab either. Thanks for the picture.
Solved that problem some time ago, wish JD would do something like this with all their snowblowers, makes storing them much easier too!
I did grind a flat area on the rod going into the sleeve so that the allen sets would hold it without spinning when the chute gets hard to turn.
