Graders are used in roadwork to both maintain and build surfaces, providing a more subtle approach to levelling off and adding camber than can be achieved using heavier and less precise equipment. Bulldozers may be used for grading work, but machines specifically designed for grading are available. They have smaller blades and a lighter construction and use wheels rather than tracks to get the job done.
Buying a used grader is a great way to improve productivity and get better results when laying tarmac. But you should consider the different grader models available and also check that the models are fully operational before putting any money on the table.

Dedicated grading machines will typically feature three axles, with two at the rear below the cab and one at the front of an elongated body, enabling the blade to sit in between for optimal performance. There are smaller two-axle models available, but they retain this same setup with the blade placed between them. A front-mounted blade may be featured on some of these units to complement the work of the central one, but this is far from a universal setup and means buyers should study the spec sheet carefully.
Grader blades may be straight, but for adding camber to the surface of a road some models are equipped with curved blades. Graders should also be capable of working on inclines and might be used to level off the surface of dirt tracks or roads that are covered in loose gravel rather than tarmac. A grader is not for use after tarmac has been laid. It is used to ensure that the surface that is going to be covered with this material will be even and flat.
This category also includes a number of bulldozers that are usually tracked rather than wheeled and offer a single straight blade at the front. While they may make a rougher job of things, they are immensely powerful and can be used to quickly make uniform large areas before a dedicated grader machine is then brought in to refine the initial work done by this heavy-duty equipment. Tracked vehicles such as bulldozers are heavier, louder and consume more fuel, but in the right circumstances will be the perfect tool for a contractor. And this highlights the importance of establishing which type of grading machine will be most appropriate to add to the plant that you use.
Graders are necessarily in contact with rough materials throughout their working lives, and thus the wear and tear to the blades, wheels, tracks and other external components can be significant over time. The undercarriage and all mechanical, hydraulic and electronic systems of a grader should be inspected before a second-hand unit is purchased. Buyers should also take note of any other additions that may be useful, such as reversing cameras, air conditioning in the cab and integrated GPS tracking to help ensure that the correct areas are being covered as efficiently as possible. With all this taken into account, a used grader can be purchased with confidence.
