When uncoupling, how should the landing gear be positioned?

When uncoupling a trailer, positioning the landing gear correctly is essential for safety and stability. The landing gear should be lowered onto firm ground. This ensures that the trailer remains stable and secure once it has been separated from the tractor unit. Firm ground provides a reliable base that prevents sinking or shifting, which could lead to potential accidents or damage.

Choosing a soft surface could lead to the trailer sinking into the ground, compromising its stability. Leaving the landing gear in the raised position would not provide any support to the trailer, making it susceptible to tipping or falling over. Adjusting to half height might not offer adequate support either and could create an unstable scenario. Thus, lowering the landing gear into firm ground is the best practice for ensuring the trailer is safely supported after uncoupling.
