The word "grader" has its roots in the Latin word "gradus", which means "step" or "degree". The suffix "-er" indicates a person or thing that performs an action, in this case, grading.
A grader is a tool or machine used to level and smooth surfaces, such as roads, fields, and construction sites. It can also refer to a person whose job it is to assign grades or marks to academic work.
The concept of grading has been around for centuries. In ancient Greece and Rome, teachers would assign students a "gradus" based on their performance. This system was later adopted by universities in the Middle Ages.
The first mechanical graders were invented in the late 19th century. These early graders were horse-drawn and used a blade to scrape and level the ground. In the early 20th century, motorized graders were developed. These graders were more powerful and efficient, and they quickly became the standard for road construction and maintenance.
Today, graders are an essential tool for a wide variety of construction and landscaping projects. They are used to level roads, fields, and other surfaces, and they can also be used to remove snow and ice.
