Stand beside a motor grader for the first time and the blade area can look complicated. There is the moldboard, a large circle, hydraulic cylinders, the drawbar, linkages and several different ways of moving what appears to be the same blade.<\/p>\n

It becomes much easier once you follow one mechanical relationship:<\/p>\n

That is the heart of the grader. The engine provides power. Hydraulics position the working equipment. The tandem drive gets that power to the ground. Wheel lean and articulation help position the machine while the blade works.<\/p><\/div>\n

For a plant operator, basic mechanics is not about stripping an engine or repairing hydraulic components. It starts with something more practical: knowing which part you are looking at, what it is supposed to do and when its behaviour has changed.<\/p>\n<\/section>\n\n

Quick answer<\/span>

What are the main parts of a motor grader?<\/h2><\/div>\n

The major parts include the moldboard, cutting edge, circle, circle drive, drawbar, saddle, blade lift cylinders, side-shift system, blade-pitch mechanism, centershift, front axle, wheel-lean system, articulation joint, tandem drive, engine, transmission, hydraulics, cab controls, scarifier and, where fitted, a rear ripper.<\/p>\n<\/section>\n\n
