Anyone know of the best place to buy QUALITY Horse tines? I am not looking for the tines that have 3 holes in them and fit multiple types of tillers. They are much easier to break if you hit a big rock because of the extra hole. I have been using TroyBilt horse tillers since 1980 and good tines are getting harder to find and much more expensive. Any information you have is greatly appreciated! Thanks! PS I have been a new member for over 20 years!
