Which operating procedure can help reduce the possibility of a tractor overturn?

Setting the front wheel width wide is a key operating procedure that can significantly reduce the possibility of a tractor overturn. By widening the front wheel stance, the tractor's base of support is increased, which enhances stability, particularly when navigating slopes or uneven terrain. This broader stance helps to counterbalance any forces that may act to tip the tractor, such as turns or changes in load.

In contrast, keeping the bucket raised can raise the center of gravity, which may actually increase the risk of overturn. Locking the brakes together can be used for certain situations, but it doesn't inherently contribute to stability while operating. Reducing tire pressure can affect traction and may also lead to instability under load. Therefore, adjusting the front wheel width to a wider setting is a proactive measure for ensuring safer tractor operation and minimizing the risk of overturn incidents.
