Question: For basic clearing of loose topsoil, what is generally the most energy-efficient blade pitch setting for a bulldozer?
Answer options:
- A highly aggressive toe-down angle.
- A slightly heel-down angle to increase carrying capacity. ✅ A neutral or slightly cutting pitch.
- A fully angled blade for side-casting.
Correct answer: A neutral or slightly cutting pitch.
Explanation: For loose topsoil, a neutral or slightly cutting blade pitch is energy-efficient because it provides sufficient penetration to gather the material without requiring excessive downward force or creating undue resistance. Overly aggressive angles waste energy, as detailed in basic HEO training.
