Sorry, but I agree with most of the others. A used grey market Japanese tiller would be the way to go. The relatively light weight Troybilt is also going to bounce around....... a lot. IMO, I think you'll be fooling around with the hitch setup so much to get it to track right........I'm sorry, I just can't imagine it
My 48-in. Yanmar was a two point tiller that I paid $250 plus $75 shipping for. I had to convert it to 3-pt. The conversion work is straightforward but would keep you a little busy anyway
But if you could find a 3-pt grey market, that would be the way to go cheap. The original curved tines are hardened.....it's the aftermarket ones that aren't. As was said, you can adapt the L-shaped HD ones from other US style tillers later on.
