Dave,

On the tripod, I think it is what it is because it is the only geometric configuration that you can stabilize easily even when the legs are not exactly equal in length and the mounting surface (floor, dirt or what have you) is not perfectly flat.

2 point will fall over.

4 or more and one leg will always carry a disproportionate part of the load if carrying any load at all.

That's what I read anyway, makes sense and I believe it.

On wide fronts, my feelings are that since the thing has one pivot point in the front of the tractor you essentially have a tripod just like the tricycle.

Difference is (my opinion) if you fall in a hole or other disturbance with one wheel, you have essentially affected half the front of the tractor not the whole thing.....but that's not to say that you couldn't still roll.

And, in turning, the force vector, like the top of your body swinging out in a turn like a car going around a curve at 60 mph, can point to the inside of "the box" with a tire out beyond you (if you aren't turning too fast) while on the tricycle, any turn and that vector is outside the tire.....hence the inherent instability.....unless you use the foot brake to turn then all bets are off.
