Question: During a typical job site where a wheel loader is frequently moving material over varying terrain, what is the primary reason for keeping the bucket low when traveling, as opposed to raised?
Answer options:
- To allow the operator to see the ground directly in front of the bucket.
- To reduce wear on the hydraulic cylinders. ✅ To maintain a lower centre of gravity, enhancing overall machine stability.
- To prevent dust generation by hovering closer to the ground.
Correct answer: To maintain a lower centre of gravity, enhancing overall machine stability.

This is critical for stability, particularly when turning, travelling on uneven terrain, or encountering unexpected obstacles, thereby reducing the risk of rolloever and improving control. This is a fundamental principle emphasized in OPSWA training.
