Hard Surfacing Tiller Tines

Is it benficial to hard surface a tiller tine that is worn down instead of replacing the tines. Has anyone ever done this? I know that the heat may change the tine' metal properties, but surious if it would hurt the tines. Thanks everyone, Benjamin

Not sure if you mean by heat treating them or building up a hard surface to add to the remaining metal. My understanding is that one side is hardened from the factory so that wear tends to cause one side to wear faster than the other and leaving at least some sharpness to the edge. Anything you'd do in heat treating is going to destroy that factory hardening. In any event it seems once worn to a certain point they don't till well (I'm told) even if sharp. I have a worn one the previous owner said "works fine as long as the ground is already tilled up." It is worn so that the end of the tines is only maybe 3/4 inch wide. I don't think heat treating will make up for the missing metal. Don

I. personally think that use of a hard surfacing rod to build up the tines would be a good thing to do. The tines are made from mild steel. I would not expect much of a heat treat in them. The hard surfacing rod will deposit a hard surface without additional heat treating. Unless a crack forms due to the heat effected zone around the weld area, I would not anticipate any problems. I will put it this way: "I would do it".

Years ago when I put a set of walk behind tines on my B-1 tiller the mounting holes were too small. The tines were hardened. Had to borrow a carbide bit from work to enlarge the holes. Also, I agree with Rod. Hard facing would be a good thing to do.

My Dad was a blacksmith He would build up plows with hard rod grind and polish them,the farmers say they wore better after being built up. I would think it sould be the same with a tiller.

If wore to bad,,,I'd go with new tines and hard face those. To "build up" the wornout ones would require far too much welding,,and heating on such thin material;).
