Motor Grader Frequently Asked Questions
Motor graders are technically complex machines requiring precise specifications for optimal results. We have answered common questions regarding grader capabilities and configurations to assist in your equipment selection process.
The blade width determines the pass width and the volume of material the grader can move. A wider blade (e.g., 14ft vs 12ft) increases productivity on open roads but may be less manoeuvrable in tighter subdivisions.
Articulation allows the grader’s frame to bend behind the cab, enabling a tighter turning radius and allowing the machine to drive in a ‘crab’ position. This is essential for grading on curves and keeping the drive tyres on stable ground while the blade works a slope.
Yes. AWD models provide traction to the front wheels, which is superior for working on slopes or in loose material where the front end might otherwise slide. Tandem drive powers only the rear wheels and is standard for flat grading.
A heavier grader generally provides better traction and blade down-pressure, which allows it to cut through harder packed material without the blade ‘skipping’ across the surface.
Certainly. SEM Hire provides high-quality motor graders for civil and mining projects. Let us know which specifications are critical for your job, and we will match you with the right machine from our fleet.
