I seen one that was similar if not the same off an 8n. It worked off cables. I bought a bunch of implements from the guy who had it. I took a quick look at it but didn't make an offer on it because I had no interest. With all the rocks I have at my place I barely use the auger I have and without a reverser trans it looks like once you get that baby stuck it's going to be hard to get out.
I was pressed for time so I really didn't get into the operation of it so I don't have any info on it. Probably could have picked it up for scrap price. All the other implements were reasonably priced.
