Motor graders are important tools to construction and engineering professionals. The machine is often used as a tool in road construction projects and building projects to make the surface area flat and prepare it for the foundation to be poured.

Motor graders have a number of important uses. In the United States, most motor graders are used primarily for road maintenance. The wide blade on the motor graders makes them especially useful for creating the wide, flat surface out of the road before the asphalt is laid down. Motor graders can be used to clean or clear an area of debris and brush. A motor grader can also be used to perfect the rough grade made by larger, clumsier machines such as bulldozers. In some more rural localities, motor graders can even be utilized for snow removal purposes, saving the municipality money by doubling the function of one machine instead of having to purchase two. With a wide range of uses and a wide variety of sizes and functions, the features a potential buyer needs to look for on a motor grader will depend on what it is going to be primarily used for. When making any large equipment purchase in Georgia, including shopping for a new or used motor grader, it is important to compare the differences in frame type, blade size and movement, weight, power, speed, agility, cost and resale value.
When purchasing a new or used motor grader around Georgia, it is important to look at different brands such as John Deere and Champion and to compare the features offered by the different companies. Comparing the frame type, blade, horse power, weight, speed, all-wheel drive ability, comfort and longevity of the machine may prove useful in determining which motor grader is right for you. The difference between the brands, including John Deere and Champion, might influence the decision that you make.
Most motor graders come with one of two frame types. The frame is either rigid or articulate. Most new models feature an articulate frame, but some models have not changed their frame design since the early eighties and nineties when rigid frames were the norm. Many used motor graders from that time period will be equipped with a rigid frame. Articulate frames provide for a wider range of motion, and allow the motor graders to be more versatile machines.
The use of motor graders is changing due to the paving of more rural roads. Because of the changes to the infrastructure system in many rural areas, motor graders have had to become more versatile to keep up with the changing times. Very few rigid frame models are still available in North America. Of the models available with an articulate body frame, there are two possible configurations.
The articulation joint can either be placed in front of the cab or behind the cab. Proponents of the behind the cab placement of the articulation joint claim it allows for a clearer view and better visibility to the moldboard. Like many other models around Georgia, Champion motor graders are designed with the articulation joint behind the cab. However, unlike other models, Champion places the transmission ahead of the articulation joint, which adds additional weight to blade and, when combined with additional horsepower, increases the production power. John Deere motor graders come with the articulation joint placed in front of the cab. Despite the fact that many of the competitors are taking the alternate route, John Deere dealers say placing the articulation joint in the front of the cab allows the operator to know where the front half of the vehicle is in relation to the back half. Models with the articulation joint behind the cab have to provide a monitor to show where that relationship.
Most motor graders come with the capacity to handle a blade width of between 2.50 to 7.30 meters. Depending on the type of work that needs to be done, different blade sizes may be necessary. When looking at different models of new or used motor graders around Georgia, comparing lift and blade rotation is always a good idea. The measurement of motor grader blade lift will determine how high the machine is capable of lifting the blade off of the ground. The type of work the motor grader will be used for and the environment in which it is used will determine how high the blade will need to be lifted. Similarly, it is important to look at the rotation of the blade. For some work, including snow removal and road maintenance, it will be necessary to angle the motor grader blade to the side. For the greatest productivity, the operator should be able to make these adjustments quickly and easily from inside of the cab.
