For deep ditch construction, what type of grading mode is preferred?

For deep ditch construction, crab mode is preferred because it allows for better maneuverability and precision in tight spaces. In crab mode, the front and rear wheels of the grader can turn at an angle, enabling the machine to shift sideways while maintaining its position relative to the ditch. This movement is particularly beneficial for shaping and finishing the sides of a deep ditch, as it minimizes the need for repositioning and allows the operator to achieve accurate slopes and depths.

Moreover, crab mode enhances stability while working on a grade, which is essential for safety and efficiency in deep ditch scenarios. This operating mode helps prevent the machine from tipping and allows it to work effectively on varying terrain while retaining full control over the grading function.

In contrast, other grading modes may not provide the same level of precision or maneuverability required for deep ditch construction, making crab mode the optimal choice for this specific task.
