What adjustments should be made when traveling over soft or unstable ground?

When traveling over soft or unstable ground, it is essential to adjust travel speed and weight of the load to ensure safe operation. Traveling at a reduced speed is crucial because higher speeds can lead to loss of control, especially on unstable surfaces, which increases the risk of tipping or the machine sinking into the ground. A slower speed allows for better maneuverability and reaction time to avoid hazards that may arise in such conditions.

Additionally, managing the weight of the load is important. Heavier loads can increase the pressure on the ground beneath the wheels or tracks, exacerbating instability. If the load is too heavy for the conditions, it could cause the equipment to become stuck or even flip over. Therefore, ensuring that the load is at a manageable weight is critical for maintaining stability and control when operating on soft or unstable surfaces.

The other options, while they might pertain to equipment operation, do not directly address the specific adjustments necessary for navigating challenging terrain effectively and safely. For instance, adjustments related to load height and tilt angle, fork length, or grip strength may be relevant in different contexts, but they do not fundamentally contribute to safe travel over unstable ground as effectively as managing speed and load weight does.
