Isn't anyone going to tell him he needs a whole set of tines? I guess you will figure it out when you get the two new ones.
Check out Fredricks' Yanmar Tiller Parts Catalog. it'sn the left column of this catalogs list on their site.
And several other Yanmar specialists sell out of that catalog too, perhaps one local to you.

I just noticed 'drive chain' in your post. I thought the Yanmar tillers were all gear drive. With the orange paint, could that be a Kubota tiller or something? It doesn't look like it would be an exact little brother to my RS1400.
