Where\'s Our Tractors\' Center Of Gravity?
Hi,
If I could only drive my tractor on increasingly steeper slopes until I rolled it a couple times! Then I would develop a feel for how stable it really is! But I can�ft...the cost of the thing prevents doing that, if nothing else does!
Now if I could estimate the position of the center of gravity, I could estimate the angle at which the tractor might tip over, at least in a static mode. By static mode I mean in a situation with no forward movement. This means little in the real world, but would give me some measurable reference to compare the real world to.
Since tractors are for the most part symmetrical, I figure that, when viewed from the back, the center of gravity would be close to the mid point between the wheels. It would also be somewhere between the two axles, perhaps under the steering wheel more or less. That fore/aft position doesn�ft come into play too much with respect to a side roll over.
The biggest question seems to be the height of the center of gravity. My GUESS is that it would be no higher than the top of the rear tires. And that it probably would not be lower than the top of the rear wheel rims. That is with loaded rear tires.
Do you think, in general terms, it would be fair to say that, as a �grule of thumb,�h a tractor�fs center of gravity would likely be located:
1. Between the front and rear axles
2. Close to the front-to-rear centerline, and
3. Vertically between the top of the rear wheel rims and the top of the rear tires?
I am pretty sure this is where the center of gravity is located, but I am not sure if it might be lower than the tops of the wheel rims.
Once I am pretty sure I know about where the center of gravity is, then I expect I can calculate the max/min angles within which a static roll over might occur.
Anyone want to suggest that I �gget a life?�h /w3tcompact/icons/grin.gif Guess it bugs me that I don�ft have a feel for how stable/unstable my tractor really is!
So whatdayathink? Am I in the ball park? I mean as to where the center of gravity actually is.../w3tcompact/icons/grin.gif
