Hitting the landing gear at a 30-degree angle when the full weight of a trailer is resting on the tractor is not recommended because it can put unnecessary strain on the landing gear and affect stability. Landing gear should be positioned vertically, allowing it to support the weight of the trailer properly without compromising the gear's integrity. When the landing gear is angled, it may not distribute the weight evenly, which can lead to issues such as bending, breaking, or improper positioning of the trailer. Additionally, maintaining the correct vertical position helps ensure that the trailer is securely supported and minimizes risks during the loading and unloading process, as well as when the trailer is detached from the tractor. Therefore, keeping the landing gear straight is essential for safety and equipment longevity.
