Question: During V-pattern loading, an operator frequently finds the bucket hard to penetrate the stockpile due to compaction. What adjustment should be made to optimize efficiency and reduce wear on the machine?
Answer options:
- Increase engine RPM and speed of approach.
- Apply down pressure to the bucket while digging. ✅ Prioritize 'crowding' action (bucket curling) over forward momentum.
- Raise the bucket slightly to skim the surface.
Correct answer: Prioritize 'crowding' action (bucket curling) over forward momentum.
Explanation: When encountering compacted material, optimizing 'crowding' action (curling the bucket) combined with the loader's hydraulic power allows for more effective penetration with less forward force and reduces stress on the drivetrain. Simply increasing speed or applying down pressure can lead to excessive wear and impact. OPSWA training emphasizes hydraulic controls for efficient digging.
