Anyone who don't know Len is, hasn't been reading the Yanmar posts very long. I have no idea, which insurance company it was, he said, but I really don't care, I have no Axe to grind, and he probably will stay out of it to, as he don't either. But if you want to spend all the time to search for it, I'm sure you will find it. And he said which company it was, as they are the ones that have to pay, if they tell you wrong, so I believe it, I really don't care if you do or not. Just telling you what he said, and he has been in the business a long time. That is all, I'm out of here, I have enough problems without arguing, with anyone.

Dick,
I recall the conversations about tricycle and wide front end tractor roll overs. Also Len Sheaffer's contributions to the discussion.
The front end width, under controlled environment conditions, made no difference during repetitive testing. Both styles of tractor rolled at the same point and time. I can't locate the specific thread in the archives, but it was either an insurance or agriculture investigation committee that did the testing.
Paddy, Len is a grey market dealer, parts supplier and I believe an authorized Yanmar (and other manufacturers) dealer in Dixon Illinois. He is near the top of a very short list of dealers who are dedicated, honest and knowledgeable. His experience encompasses many makes and models of grey market tractors and heavy equipment.
***edit*** I have read many official findings about wide front ends preferable to narrow when bale spears, loader and other attachments mounted to the two styles of tractor.

I think the opening diagram and third paragraph proves the point. Perhaps the insurance study was in reference to a rearward overturn.
For a tractor to stay upright, its CG must stay within the tractors stability baseline. Stability baselines are imaginary lines drawn between points where tractor tires contact the ground. The line connecting the rear tire contact points is the rear stability baseline, while the lines connecting the rear and front tires on the same side are the side stability baselines. Front stability baselines exist but have limited use in stability/instability considerations, and are not normally include in such discussions. See Figure 1 for a complete illustration of a tractors CG and stability baselines.

do you only fill the rear tires? or is there not enough benefit in filling the front due to small size? when you fill the tires is there more potential for punctures?
thanks mark
thanks mark
No you are wrong again. You should be able to figure out, that the width of the front end would have nothing to do with it upsetting backward. But I think you are going to be right in your mind no matter what, so think what you will. I don't know how to bring up the post I am talking about, but if you search under "front wheels" it is posted on 5/29/05, by Len. Do whatever you want, I'm sure it won't make much difference to you, no matter what it says, or anyone else for that matter. You have your mind made up.

Dick,
I did not to intend ruffle any feathers by asking what your source was or what study was performed. I'm a mechanical engineer and it's in my nature to review statements.
I have not spent much time on this section of TBN, though if you view my stats, I'm no newby.
I will review Len's roll over theroies.

I guess you misunderstood me. I never said Len had any theory's about rollovers. A theory, being an unproven belief. I said he saw it proved, so it isn't a theory. He didn't do it either, an insurance company in the farm business did the proving. So Len had nothing to do with it, just told what he saw. I understand how people think a wide front end would help, I use to think the same thing, but as I've got older and had more facts to deal with, I can also understand how it wouldn't with the center pivot, letting it flop. The first tractors I used back a lot of years ago, about all you saw was the narrow ones. Of course that was 50 years ago. My folks wouldn't have a tractor while I was growning up, as our land was hills steep hills, and they didn't trust them. So I was grown and out on my own before I got to drive a tractor.

I think I was the one that asked the question .I wanted to know if I turned my front tires out on my tractor would it put any undue stress on the front end parts. I stated I wanted to turn the front tires out to make the tractor more stable.I don't remember who posted it , but they posted insurance test that showed it didn't make a tractor more stable to make the front wider.
Well i have a 1500 series and my land is very hilly pasture land and some areas are tough and if I was not careful I would turn the tractor over. But most rollovers are due to inexperience or carelessness. Not that it couldn't happen to me becauses accidents happen but I am mindful of where I am, I bushhog up and down hills not side to side, I keep the bushhog low just in case I get off center (I use a 5ft bushhog). Many believe a tractor can go anywhere or do anything which isn't the case just like a 4 wheel drive in snow and icy conditions, you still can have a accident just as quick with a 4wd as not if you are careless.
