I think he is saying that the pivot is 3 feet above the location that their gearboxes are mounted, not their arm is 3 feet long, but I could be wrong.
Question: is the ratio between your tough boxes and the hex shaft of the arm 1:1? If so I think this is your problem, try using a much larger pulley on the hex shaft. Or a smaller one on the tough box, or both.
