Aerator Tine

[Junkman]

Nomad....... you are trying to reinvent the wheel. Too much effort has already gone into this thread and it is going no where, because if it isn't broken, it doesn't need to be fixed... I am out of here..... /forums/images/graemlins/frown.gif /forums/images/graemlins/confused.gif /forums/images/graemlins/grin.gif

My question was simple: "Why is that tine curved?"

Your answer too was simple, but wasn't an answer to my question.
</font><font color="blue" class="small">( It is curved b/c someone took the time and effort to specify that it should be curved.)</font>
Is this an answer?
You must be feeling that you have to protect somethings/someones who you consider they spent efforts.

Villengineer, the science isn't only to invent new things, adding somethings new into the world, life, etc. The science is also to "correct" the errors in the past and this is more important than adding new things in our era because the science, technology, world, life, etc are full of errors. In this era/age, to me, all scientists should stop adding newer and newer things and should start to look at their behind to see their dirts which will show them they have been on the wrong way. Such a science philosophical movement among "true" scientists has begun a decade ago. They are now questioning everythings behind, in past. Step by step. In coming years/decades, inventing/adding new things will not be as worth as locating the errors/mistakes/etc in the past. This is the science of coming years/decades. Such a science feedbacking the past, working toward the backward will/may show that many things today are (maybe) completely wrong. So, the science I am doing here is the science of future, that is, questioning the past. That's why I am asking "why is that aerator tine curved?" Explain the reason and I will show the error and showing the error too will be a "new invention" if you credit only "the new" to you.

Look at your own diagram of the tine entering the soil. You should be able to figure out why the curved tine is marginally better than a straight tine. You should also see that there is very little to be gained by complicating that which has already been done. The fixed tine rolling style aerator is fundamentally flawed as far as "optimum" performance is concerned. However, I suggest that it is most likely adequate for what consumers want it to do, in it's market segment, and therefore there is little to no gain in changing it. Certainly not for fuel efficiency reasons. Besides, if the consumer truly must have a vertical insertion/retraction then there are other designs, though considerably more $, which do that.
Oh yeah, on your whole little soap box about the future/past: it causes me to think of a saying I like. If you aren't moving forward, then chances are you are actually moving backward.

Sorry, I don't have a digital camera. The spoon is a piece of stamped steel. Not being a mechanical engineer, I'm guessing one die stamped out the blank and another formed the blank into the spoon including the curvature. Other than sharpening one end and painting it, that's all that seems to be involved.

When any person reading this thread who doesn't understand the technique, but with a good logic in his/her mind reads your this post supposed to be an answer to "why a certain curvature in the tine" will probably think that he wasn't satisfied with your answer. You are saying him/her somethings like "hey, look at the shapes of straight tine and curved tine - you see curved tine is better, has better performance." He/she is probably opening my diagram again and again and still unable to see the effect of curvature there.

Okay, I am not "any" person. Then, what am I thinking now after reading your post? Without running my technical gears in my mind, but running only "logic" gears, here is what I think; You say :
1. curved tine has better performance than straight tine. Really?
2. If yes to (1), then the question is; is the current curvature of that tine "optimum"?
3. if yes to (2) (if it is optimum), then there is no further study in the tine needed anymore as nothing left in it to research. If so, then no need to hide any info about it as it reached at the optimum configuration.
4. if it is not the optimum, then the questions (I am asking in this thread) arise; "Why that curvature in the tine?", "why not another curvature?"

No engineering knowledge is necessary in the questions above. Any person with a well working logic gears in his/her mind can see my those questions above made a close loop which you can go out only by answering one of those questions with a logic. Ps: you are trying to "use" "the oil" to escape out of the loop.

Dogonit Nomad; why you asking all these highly technical questions ? With the all the degrees you have why not sit down, write a program that will solve the angle problem, get out the old key punch and get the cards punched and then run the program. Let us know which is best.

I have done all these you said, Egon. And, the result is "computers are unable to answer the questions beginning with WHY" - Why?

 

[Egon]

But that's what you are there for Nomad. The computer is just a high speed aid for crunching senarios. It's your program you have developed that does the thinking.

Sir.. I have an old tow behind aerator which is in reasonably good condition except that the tines need to be replaced. I've been searching for replacements and happened to notice your posting. It's a curved tine and looks exactly like the one in your photo. Are these available for purchase?
