How does raising the loader arms while moving with a load affect stability?

• A. It lowers the machine’s center of gravity, increasing stability
• B. It reduces tipping risk
• C. It has no effect on stability
• D. It raises the machine’s center of gravity, increasing tipping risk and reducing stability

Answer: (D)

Raising the loader arms while moving with a load shifts the center of gravity upward. A higher center of gravity makes the machine more top-heavy and reduces its stability margin, especially on slopes, uneven ground, or during turns. Stability depends on how far the center of gravity sits within the base of support; lifting the load raises the CG and increases the tipping risk, so overall stability is reduced. To maximize stability, keep the arms down and the load as low as possible when moving. Raising the arms with a load creates a higher CG and therefore a greater chance of tipping, which is why that action is risky.
