This 1981 Caterpillar 12G is a used motor grader — sometimes called a road grader or grading machine — offered for sale in Arizona, USA at $60,500. Motor graders are heavy construction machines designed to fine-grade and level soil, gravel, and other materials, producing flat or precisely sloped surfaces for road construction, site preparation, and maintenance work. Caterpillar is one of the world's most widely recognised manufacturers of heavy construction and mining equipment, with a long-established reputation for building durable, productive machines across earthmoving, road building, and infrastructure applications.
This machine is equipped with a 14-foot moldboard, the primary working tool of any motor grader, which is used to distribute and finish material across the full working width in a single pass. A rear-mounted ripper is also fitted, allowing the operator to break up compacted ground, hardpan, or light rock before the blade works the surface — a useful combination for road rehabilitation and reclamation projects. A push block is included as well, extending the machine's versatility by enabling it to push other equipment or materials when needed.
The machine features accumulators, which are hydraulic components that help maintain consistent blade and system pressure, contributing to smoother operation and more responsive hydraulic performance in demanding conditions. It runs on 17.5 x 25 tires, a common size for machines in this class. The operator station is an OROPS — an open rollover protective structure — providing rollover protection in a cab-free configuration. The machine is presented in used condition, reflecting its 1981 vintage.
