Center of Gravity

[4runner]

Is there a listing or spec item for a tractor's static center of gravity?

I am looking at a JD 4110 and I took a second look at it yesterday. The 4110 was parked next to a 2320, and the 2320 looked much taller than the 4110.

Is there anyway to compare the CG other than the eyeball method?

I requested same info from John Deere via email before purchasing last year and they referred me to the JD Dealer. Dealer could only speak in generalities, like putting wheels on wide position vs narrow, liquid ballast in tires, wheel weights, ballast box, cab vs non cab, etc. -- most of which I already knew.
Let us know if you can get more COG specifics.

Yeah, that's pretty much what I've gotten so far. I know it is a very difficult question, because when you add the "dynamic" case of movement and uneven terrain, there is a large amount of variability. Still it would be helpful for side by side "all things being equal", the CG of tractor A is lower than tractor B.

I have never seen a published spec on COG. I assume there are just to many variables to cover. With that said, I do think the newer 2320 and 2520 "look" taller but I have never compared them side to side. I can help answer any specific 4110 questions though...

I don't have any COG info on the 4110 but I do know from personal experiance that the 4110 is a great little tractor!

I think they could list it along with a "standard spec" disclaimer, e.g. with ag tires, width doesn't matter.
I suspect that the reason they don't is because it is alarmingly high on most tractors and nobody wants to start a "specs war" on that particular parameter.

To MEASURE it I'm thinking I would;
1) weigh each wheel when level (OK techies, I really mean measure the load at each wheel).
2) raise one side some carefully measured distance (about a foot) and weigh them again.
3) puzzle over the numbers and somehow figure it out.

Option B;
Use ropes, chains, a stout anchor point;
Tip it until it is balanced on one front and one rear wheel.
This would give the roll over angle, which is probably more meaningful.
Even MORE meaningful with a (standard spec) operator, but it is still only a static measurement.
