What can you use a 12M grader for?

A 12M grader is a powerful, versatile grading machine that is designed for grading, levelling, and maintaining roads and other sites. Part of Caterpillar's M Series of motor graders – which are known for their advanced technology, efficiency, and precision – the 12M grader has a powerful engine, mid tandem axles, and robust hydraulics that make it capable of working on a wide range of terrains and projects.

The most fundamental of these uses is for road construction, where it can grade and level the road surface to ensure a smooth, even result. But some of the other most popular uses for a powerful grader like the CAT 12H include:

  • Levelling and grading of construction sites

  • Clearing and grading of land for building sites or agriculture

  • Landfill construction and maintenance

  • Mining operations – including grading of haul roads and tailings dams

  • Airport runway maintenance and construction

  • Building and maintaining dirt and gravel roads

The 12H grader is an older predecessor to the 12M, which has a similar engine power to the 12M, but its transmission system has only six forward gears as opposed to the 12M’s eight gears. The 12H also has a smaller mouldboard than the 12M.

The 12G grader has a more powerful engine than the 12M, with up to 279 kW (373 hp) of net power, and also has a larger mouldboard than the 12M, which measures 4.3 meters wide and 762 millimetres tall. Additionally, the 12G has a more advanced control system, including an optional GPS-based grading system.
