Why is it important to secure loads properly on a tractor?

Securing loads properly on a tractor is crucial mainly to prevent shifting that could lead to loss of control. When loads are not adequately secured, they can move during transport, altering the balance and center of gravity of the tractor. This shift in weight distribution can cause the tractor to tip over or make it difficult to steer, especially on inclines or during sharp turns. A stable, secure load ensures that the operator can maintain control of the vehicle, minimizing the risk of accidents and injury to both the operator and others on the road.

The option related to improving fuel efficiency pertains more to operational performance rather than safety and control, while enhancing aesthetic appearance is secondary and does not prioritize safe handling. Increasing weight capacity might seem advantageous, but it becomes irrelevant if the load is not secure, as the key concern should always be maintaining safety and control over the vehicle while transporting any load.
