I have never seen a Flail for a Super A, so I cannot say if they are the smae, but considering the higher horsepower of the A I would suspect the mower for the A to be wider. They did make a 5 foot Mott that was sold for cubs, but it was an extreme load for them in anything but very easy cutting. As has been mentioned, pto rotation is different, but that is easy to solve. The belt makes a half twist with the side coming from the outside pulley going on top of the mower pulley, for an A just put the inside belt on top. The rpm difference will be a bigger challenge. The Mott runs about 2,000 rpm at full throttle on a cub which is where it cuts best. To get the same rpm from a Super A you will need quite a bit bigger pulley on the SA. according to my figures it would take approximately a 26 inch pto pulley to give the same mower rpm unless you used a smaller pulley on the mower, which would give it more of a tendency for the belt to slip. The bigger flails I have seen had a larger diameter, and since the cutting was done by the inches per second the ends of the knives travel, the same as a lawnmower blade, they could be spun slower. How is that for muddying the water?
