A rock , as You described , would cause a large vibration . It is the smaller vibrations , that most don't notice , that cause issue's down the road . Seals , Bearings , take the brunt of that wear . Larger tillers usually have better support , thus a dampening effect through the system . Yes , one can replace a broken tine , most may not even notice any change . My Dad replaced broken tines by keeping older ones from his tiller and also picking up others from people who were going to discard their old ones . He then would replace the broken one with one that was close to approximate size , shape and weight of a couple of others that He would pull as samples . In the Decades that He ran that tiller , Never replaced a seal , bearing , Shaft , gearbox or had any PTO issue's of any kind .
A spinning mass , although not running at the same speed as a tire on a car , still needs to be balanced to a degree .
Not arguing with You TerryJust know what worked for my Dad , thus I try to follow suit . :thumbsup:
Not sure the exact size of that old tiller . maybe in the 60" to 72" class , It was used a lot for initial ground breaking on virgin soil for people around the neighborhood who started gardening area's back in the days . Another thing that comes to mind was the tractor itself . Were as newer tractors today likely have better suspension from seats to , well everything , That old tractor , could bust a kidney .

Fred H. No worries. I guess what I SHOULDA said was I agree that I'm certain that a spinning rotor WOULD be unbalanced with unequally weighted blades.
I think that any vibration was just not noticeable with the sheer weight of the machine and tractor. Plus perhaps I'm not the most observant person around.
I' d like to mention that the OEM blades on our (original Made in England) Howard tillers had a warranty against breaking as long as it was not WORN more than 50%. Within those conditions we NEVER broke one. The only breakage we'd have would be if a bolt worked loose. Then the "break" would be through the bolt hole and not warrantied.
My last big tiller was a Terranova. Within the first 50 hours EVERY blade bent. NO breakage, no wear, all bolts tight. BENT.
The dealer gave me a replacement set and the same thing happened. I eventually found a better line of blades before I sold the machine.
