Beat me to it. That's what I would look at doing in this case since you have no idea who really made any of it.You sure you didn't buy that from my brother-in-law? I narrowed his post hole digger and he ran it from new with no gear oil or grease in the joints. The deck looks in nice shape. How much is it to find a gear housing unit and replace it? It may be easier to fit that to what you have.
