What is the effect of using a bucket with a height that is too high during lifting on uneven ground?

• A. Using a bucket with excessive capacity reduces stability and increases load on the engine and hydraulic system.
• B. Using a bucket with excessive capacity improves fuel efficiency.
• C. No impact on performance.
• D. Using an oversized bucket increases breakout force.

Answer: (A)

Raising the bucket too high while lifting on uneven ground raises the center of gravity and enlarges the tipping moment around the wheels. On uneven ground, the support under the machine isn’t uniform, so a higher load makes it easier for the loader to tilt toward the lower side. The higher the bucket and load, the more the gravity force acts to tip the machine, reducing stability and increasing the risk of an overturn.

Additionally, holding or lifting a high, heavy load demands more hydraulic pressure and engine torque to fight gravity, increasing the load on the hydraulic system and engine rather than improving efficiency. The idea that it would improve fuel efficiency isn’t correct, and stability, not zero impact, is affected. Breakout force isn’t increased by simply lifting the bucket higher—the position mainly affects stability and the required lifting effort, not the basic breakout capability.
