I haven't, but I'm not sure it would do any good. I run out of clearance at the back tires. Swinging the rake around hits a tire before hitting anything else, hard to visualize without a picture, I know. I think instead of a shorter top link, it would have to be a much longer 3pt hitch frame to extend the rake farther back away from the rear of the tractor. I don't think I have any pictures of it hooked to the 3 pt for reference.
It's not a huge deal, but on the rare occasion where I would want to rotate the rake all the way around, it would be nicer to do it while it's hooked up. Instead of unhooking it and trying to keep it balanced while walking the hitch around.
