How do implement position and track width affect a tractor's lateral stability when driving across slopes (Hangneigung)?

1. Raising implements lifts the centre of gravity and sharply increases rollover risk, so implements are kept low and, where the machine allows, the track is widened
2. Raising a heavy implement to full height always stabilises the tractor on a side slope
3. A narrower wheel track increases stability by reducing the leverage of side forces
4. Implement height only affects stability once the tractor is stationary
