"Construimus, Batuimus." ("We Build, We Fight.")
- Motto of the US Navy Construction Battalion, the 'Seabees'
A grader, also commonly referred to as a road grader, a blade, a maintainer, or a motor grader, is a construction machine with a long blade used to create a flat surface. Typical models have three axles, with the engine and cab situated above the rear axles at one end of the vehicle and a third axle at the front end of the vehicle, with the blade in between. On certain countries, for example in Finland, almost every grader is equipped with second blade that is placed on front of the front axle. Some hard hats refer to this machine as "the blade".
In civil engineering, the grader's purpose is to "finish grade" (refine, set precisely) the "rough grading" performed by heavy equipment or engineering vehicles such as scrapers and bulldozers.
Graders can produce inclined surfaces and surfaces with cambered cross-sections for roads. In some countries they are used to produce drainage ditches with shallow V-shaped cross-sections on either side of highways.
Graders are commonly used in the construction and maintenance of dirt roads and gravel roads. In the construction of paved roads they are used to prepare the base course to create a wide flat surface for the asphalt to be placed on. Graders are also used to set native soil foundation pads to finish grade prior to the construction of large buildings. Special Order!

Historical Account: "Constructs" - In December 1941, with U.S. involvement in war soon expected on both oceans, Rear Admiral Ben Moreell, Chief of the Navy's Bureau of Yards and Docks, recommended establishing Naval Construction Battalions (from which the abbreviation C.B. became Seabees). With the attack on Pearl Harbor and the U.S. entrance into the war, he was given the go-ahead. The earliest Seabees were recruited from the civilian construction trades and were placed under the leadership of the Navy's Civil Engineer Corps. Because of the emphasis on experience and skill rather than physical standards, the average age of Seabees during the early days of the war was 37. More than 325,000 men served with the Seabees in World War II, fighting and building on six continents and more than 300 islands. In the Pacific, where most of the construction work was needed, the Seabees landed soon after the Marines and built major airstrips, bridges, roads, gasoline storage tanks, and quonset huts for warehouses, hospitals, and housing.
With the general demobilization following the war, the Construction Battalions were reduced to 3,300 men on active duty by 1950. Between 1949 and 1953, Naval Construction Battalions were organized into two types of units: Amphibious Construction Battalions (ACBs) and Naval Mobile Construction Battalions (NMCBs).
The Korean War saw a call-up of more than 10,000 men. The Seabees landed at Inchon with the assault troops. They fought enormous tides as well as enemy fire and provided causeways within hours of the initial landings. Their action here and at other landings emphasized the role of the Seabees and there was no Seabee demobilization when the truce was declared.
