Can all tractors flip over easy?

[LouNY]

Yes they are. It’s a lot easier to tip a triangle on it’s side VS a rectangle due to the center of gravity being closer to an edge of the connecting lines. It’s been discussed and proven many times here on TBN over the decades.

Bull; and I have said so many times, it has been discussed many times it has NOT been proven.
There are so many old wives tails being presented as facts that you can't find the grain for all the chaff flying around.

added as an edit;
And your diagram is an example, were is the front axle pivot point???????

I know from your tone that there’s no way to convince you, so I won’t try, other than to point this out, yet again. If the CG travels past any of the baselines, the tractor tips over. The baseline is closer to the original CG on a tricycle tractor. If the CG moves along the red lines I’ve drawn, as soon as it crosses the baseline, over the machine goes.

The CG can cross the baseline sooner on the tricycles than the quads.

Very nice sketches just one problem, redraw your red lines using the pivot point of the front axle on a tractor.
The front axle is not rigid it pivots at the center so there is almost no difference if your sketches are drawn correctly.

A pivoting axel will stop before a rollover is reached making it act more like a square vs a triangle. Overall a 4 wheeled tractor is a lot more stable than a 3 wheeler. Maybe if you were working on steep ground without a loader and the tractor is rolling because the rear tire dropped in a hole the front axle type wouldn’t make much difference. But that’s probably the rarest kind of rollover. In s much more common scenario working on mostly flat ground with a loader the pivoting axel helps a lot.

Revise your sketch to use the front axle pivot and then look at your drawings again.

Not if you are traversing a sidehill, your entire tractor is tilted sideways but the axle has not started to tilt and will not untill the rear uphill tire starts to lift, by the time you get to your front axle pivoting stops they will do you NO GOOD you are going over.

I edited my first post but there’s lots of pictures of tractors driving with an uneven load in the loader with one back wheel off the ground and the front axle on the stops. Such a task would be impossible if it was truly no different than a triangle. It takes a lot of hill to roll a tractor based on gravity alone. I would guess rolling them on a lesser hill due to the loader being high is way more common.

Like I said, there’ll be no convincing you on this topic. Most will agree with what I posted.

No convincing because your drawings don't align with reality. I have not clue how many agree, but that doesn't matter; what matters is the physics of the situation, some drawing.

Here's what it really acts like:
