Although it's possible your solution would be long, I'd say post it at least one time and then refer other to that original post. The advantage of that is to have it in a public space instead of having to email it each time to people.
So far, my lawn tractor is working flawlessly but time seems to be my enemy with this model but I'll continue to do the proper maintenance with hopes I won't have get into the engine.
That would be fine if one was sure that the original post would remain on line & accessible and the person with the problem was going to search the archives to read it, most won't .
Then there is the problem of it getting lost in a long line of contradictory post usually by face book experts with next to zero practical hands on knowledge.
Then one has to go back and prove to some clot who gets his jollies ( they are always male ) by tearing down others that you are correct but most of these keyboard heros can not follow logic then they bring up all sorts of totally irrelevent web pages by reputable people that are b not appliciable to prove their case.
Look at all the ho har about synthetic oils, most posted by people who have never studied oil & lubrication for even 1 second.
Or the rubbish about exhaust valve recession from the use of unleaded fuels cause by idiots extrapolating lean burn aero engines running at 20,000 feet or higher to vehicles running on terra firma.
Or ethanol fuels ( which are not petrol ) degrading over time and you will get a tyrade of replies from people why have zero understanding of the physics & chemistry behind it chiming in that is is rubbish cause their second cousins brothers uncle runs his mowers on fuel his grandpappy hid in the cellar during the Civil War to prevent them dam Yankees getting their hands on it and everything runs just fine on it .
Then you get people who misquote you and try to make a case out of it,
Note in Post # 3, I mentioned SUB 40000 rpm mower engines , 4000 rpm being the absolute maximum upper rev limit on most mower engines, note LIMIT, not operating speed.
Which then got misquoted in post # 9 as being a running speed.
Now I usually can not be bothered answering such posts as all it dose is waste my time and inflate the ego of the poster.
You came here with a problem, and were given good advice, namely yes you can use a steel rod but you should find and rectify the problem that is causing your alloy rods to break in the middle because this is a rare situation and indicated a problem elsewhere.
Yet rather than accept this you are now turning the thread to attack the very people who are trying to offer you very valuable assistance, free of charge.
I have little time for such behaviour so this will be the last one of your posts that will get a reply from me.
Good luck with your mower but don't be suprised when the rocker stud pulls out or if the steel rod bounces off and trashed the bottom end, we tried to warn you.
