A grader, also known as a motor grader or road grader, is a heavy construction machine used to create a flat surface during the grading process, which is essential for road construction, landscaping, and other infrastructure projects. It consists of a long blade that can be adjusted to different angles and heights, allowing it to precisely level and smooth out large areas of soil, gravel, or other materials. Graders are often equipped with additional features like front and rear axles, a cabin for the operator, and sometimes even GPS systems for enhanced precision.

The primary function of a grader is to create a smooth, even surface for roads, highways, and runways, but it can also be used for tasks like ditching, leveling land for construction sites, and preparing surfaces for asphalt or concrete. Graders come in different sizes, from smaller models for light-duty tasks to larger, more powerful ones for heavy-duty work. Modern graders are equipped with advanced hydraulic and electronic controls that allow for better accuracy and efficiency, ensuring that roads and other surfaces are level, properly sloped, and safe for use
