Thanks for that info, that is about the only difference between the 2 tillers that I can tell.
I'll have son will bring the tines from the other one and we can try them out before doing any welding on this one.

I got a real workout yesterday from it. gotta get it fixed. I'm thinking we can weld some extra metal onto what is there...just to beef it up, they really sharpened it a lot. thin & pointy edges.
