b2650 almost rolled need front wheel spacers

I think I can answer this one. I feels like you had your chance. You ignored your margin of error and you F'ed up. Here's your sign.

Nothing to do but throw a rag in the run away engine inlet, pull the tractor upright again and immediately try to start it.

And then post a question on TBN as to why the tractor engine has developed a hard knock after being tipped.

But the math said it wouldn't tip!

If you REALLY want to engage the front axle for rollover stability, you can add a front roll stabilizer bar from a small FWD car. Attach the car's original 'body mounts' to the bottom of the tractor frame and the F/A links to the front axle somehow. Otherwise, there is no practical reason for front wheel track width increases. By the time you hit the front axle's maximum roll stop, it's generally too late and the contact from the axle beam's roll angle constraint constraint will contribute a 'jerk' to any roll momentum. Jerk being the rate of change of roll acceleration. That's the Vehicle Dynamics.
Even if the front axle were solidly mounted (no axle roll freedom, the total C.G. height (tractor + loader + belly mower + weight box, plus fuel load, plus driver's bellymore) is the most important single parameter. Actually, partially loaded rear tires help, too, because the liquid ballast level kept low will bring down the C.G. a bit.
Tires are important, too, because sliding sideways is the goal if you are on a hill sideways. Good lateral grip is bad for rollover.

I like the way you chime in for the question posed to others.

If you add a "sway bar", you will give up a lot of Traction in many situations!

I find your position flawed, and wish to provide common sense to the thread.

I guess so. Going straight ahead, the bar is not in-action, In turns on all surfaces, the outer tire will give up grip (that's good for rollover) and you'll need a bit more steer angle to keep on a turn radius. In turning and tilting in a plowing situation, I can see a loss.

But if you are upside down or on your side, you have zero traction.
I'd propose a coupler or detachable link on one of the bar's axle mounts to let you disengage it when you feel it's safe to do so. Somebody could probably even come up with a dashboard switch labeled "Tilt Reduction" that engages a magnetic coupler. Equipped with an electric pendulum, maybe come on automatically.

The off road "JEEP" folks have quick disconnect anti sway bars.

So it is "a thing". ;-)

60years of operating tractors and trucks in Tennessee hills you learn quick what works and what doesn’t. Widening the rears and proper ballast helps. Operator is the biggest variable. What one can do safely can kill another. No chart or pencil whipping math can cover all the dynamics to keep you safe. Can’t always predict the winner of a horse race. Can feel the stability differences. It’s good to be scared. Scared keeps you safe. While FEL are very useful they are probably the most hazardous attachment.
