A tractor tips when the centre of gravity moves outside the "stability baseline" - an imaginary line connecting each wheel.



Instability can tip a tractor sideways. The outside wheels become pivot points.

The outward tipping force varies according to the tractor speed and turning radius. Sharp turns increase the force.
A tractor is more unstable when turning uphill. Avoid this type of turn whenever possible or make it at slow speed.
The force becomes more dangerous as the tractor's centre of gravity is moved higher. Examples are when a front-end loader is raised, or when spray tanks are mounted high on a tractor chassis.
