Question: During a final grading operation on a sloped area, the excavator operator notices that the grade stakes indicate a finish grade of a 3:1 slope (horizontal:vertical). What is the most effective technique for achieving a smooth, consistent finish using the excavator's bucket?
Answer options:
- Dragging the bucket with the cutting edge angled slightly upward, starting from the top of the slope.
- Digging small trenches horizontally along the slope at each grade mark and then filling them. ✅ Using the bucket's backfill blade to 'cut and carry' material downslope while maintaining a consistent angle.
- Repeatedly pushing material upslope with the bucket until the desired grade is achieved.
Correct answer: Using the bucket's backfill blade to 'cut and carry' material downslope while maintaining a consistent angle.
Explanation: Using the bucket's backfill blade (the flat back of the bucket) to 'cut and carry' material downslope while maintaining a consistent angle is a common and effective method for achieving smooth, even finishes on slopes. This technique minimizes divots and humps, allowing for precise material movement for fine grading.
