Has anyone mounted a bucket for carrying sand on a super 20?
They made a bucket for the super 6 so you could copy that or mount an available bucket. That would be a big bucket on a 20. The tilt cylinders might not have as much range as you'd like, for dumping and tipping back. The factory bucket was a flat forklift style bucket for loose materials only I'd assume.
What is the age of your Super 20? Serial Number? I will tell you that the boom design is for lifting, not pushing. I had a customer in Chicago years ago that would clamp a railroad tie in the pipe clamps and use it to push snow from the parking lots. They bent the booms on both machines.
