Hill Climbing Primer

Ovrszd; surely reads like we're being flamoosaled by a couple of folks thinking themselves to
be educated and knowledgeable far and above us shorter word challenged fellows and we should just blindly accept our lack of education and Their knowledge.

No doubt we were all wrong eh!

Dont know the term flamoosaled, but it sounds like you think someone is trying to fool you.

... Yes you were wrong when you said that it doesnt matter how low you hitch - and also kept ignoring stipulated steady state pull conditions.

I sure wish I could see the conditions leading to the reported flips from fixed drawbar pull. The happenings are statistically rare and hearsay "description" is sadly lacking analysis for the specific cases. Whatever led to them needs a close look and should be accurately conveyed to tractor people.

Google "Tractor rear overturn" and see the results it gets.

In highway mowing, rear tip overs or happen less frequently than side roll overs, yet account for more deaths because reaction time is far less. About 1.5 seconds due to wheel torque, where as in a side roll over, gravity does the work more slowly giving the operator more time to react.

There ya go again...... Calling the opposition "wrong". I don't get that. Again I say, I can only assume that means you have no further evidence to prove your point so you accuse the opposition of error??

I'm fairly sure Egon and/or myself have never called you "wrong" or any of the other condescending terms you've used in reference to us. But then I'm sure if we did you will copy/paste every one of them in your reply, along with several of your previous statements as if we might have missed reading them.

You apparently have missed reading them, because in the face of a composite of convincing evidence presented you still make the same claim invoking a defined motion that is prevented by the test configuration.

I have used no condescending term in reference to you but you have used at least one.

Theres absolutely no detail there. They dont even mention hitch point. No account Iv ever read discusses the specific details of a rear tipover. Id be interested to see a thorough investigation of cause if you find one.

I'd guess that drawbar weight has a significant effect on the situation, such as towing a 6000lb batwing up an incline. There is a pretty great downward pressure on the drawbar in that situation. Also if the operator stopped, or even rolled back slightly, and then accelerated that would be another recipe for disaster.
I would agree with your inclination that drawbar height does have much to do with how easy a rear tip can occur.

Well, we have improper hitching. And we knew that was a problem. Detail on instances with proper hitching is where to look for the mechanism by which the built in safety parameters somehow are bypassed by specific circumstances.

Or maybe a rear flip is possible when hooked below the drawbar.

Maybe inspect your parameters for obvious overlooked items you can get your head around.

Yep.

I give Larry credit for trying real hard to dummy it down so I can understand it. But he continues to add stipulations to my simple statement. It's obvious to me that it does not matter to Larry what my statement is. He will continue to dispute it. Even though in one comment he admitted that the front of the tractor would lighten in my stated situation.

CalG gives my statement no credibility and matter of factly states so.

I have tried to always stick to the facts of my statement. I've also tried to get a simple answer to my questions. I now believe that is not possible from Larry or CalG. It's just not in their nature to put this situation into daily use terms. Instead they try to complicate it with lengthy dialect about varying situations and conditions.

So, I am left with little to add.
