When uncoupling a trailer, the landing gear should be:

• A. Lowered before brakes are set or wheels are chocked
• B. Lowered onto firm ground
• C. Lowered to raise trailer 6 inches above tractor height
• D. Lowered after the trailer is uncoupled

Answer: (B)

When uncoupling a trailer, it is important to lower the landing gear onto firm ground to ensure stability. This practice helps to distribute the weight of the trailer evenly, preventing any shifting or rolling that could occur if the ground is not stable. By establishing a stable base, the risk of the trailer tipping or becoming difficult to control is minimized, ensuring a safer environment for the operator and others nearby. Lowering the landing gear onto firm ground also allows for easier maneuverability when reconnecting the tractor later. It provides a solid anchor for the trailer, making it less susceptible to wind or other external forces that could cause it to move unexpectedly. This approach is essential for maintaining safety protocols during the process of uncoupling and re-hitching that heavy loads involve.
