When operating around a ditch, look ahead for holes, gullies and wash-outs. Stay away from ditches and riverbanks where possible. If you can't, look and think ahead. Reduce speed when turning or crossing slopes and on rough, slick or muddy surfaces. Slow down before making any turn.
Centrifugal force is one of the major causes of tractor upsets.
As you double the speed of a tractor while turning, the danger of upsetting is increased four times. Reduce speed when turning with a loader. As you turn with a raised loader, you increase the possibilities of a tractor overturn. Keep the loader as low as possible, and watch for ditches, holes and rocks that might cause an upset. If a tractor begins to slide sideways in the direction of travel, you may tip over in a ditch or run into an obstacle and upset.
