Which tool is specifically designed for ditching?

The grader is specifically designed for ditching because it has a long blade that can be adjusted to create smooth, precise grading on road surfaces and for managing drainage. When it comes to ditching, the grader can effectively shape the sides and bottom of ditches to ensure proper water flow and drainage. The angled blade allows for efficient cutting and moving of material, making it ideal for creating and maintaining ditches alongside roadways.

Other tools like the excavator, backhoe, and bulldozer may be capable of performing ditching tasks, but they are primarily designed for different functions. The excavator excels at digging deep holes and moving large amounts of earth, the backhoe combines digging and loading capabilities but is more versatile for general construction tasks, and the bulldozer is primarily used for pushing large quantities of material across a surface. While these machines can be used for ditching, they do not specialize in this specific task to the extent that a grader does.
