KOMATSU G990 MOTOR GRADERS

The Komatsu G990 is a heavy-duty motor grader designed for precision grading, leveling, and earthmoving applications. Powered by a 225 horsepower turbocharged engine in first gear, this machine delivers robust performance for demanding construction projects. The moldboard measures 14 feet in length with a standard height of 31 inches, providing versatile cutting and filling capabilities. The blade system features a maximum shoulder reach of 89 inches on both left and right sides, with moldboard sideshift capabilities of 5.30 inches left and 29.5 inches right for enhanced maneuverability and grading precision. The machine maintains a 17.5-inch maximum lift above ground, enabling efficient material handling and contouring. Weighing 48,720 pounds, the G990 offers substantial blade down-force and drawbar pull for tackling heavy soil conditions. Its steering system incorporates a 21-degree articulation angle with a 26.8-foot turning radius, enabling tight operational control in confined spaces. The machine's advanced hydraulic system utilizes proportional demand flow and load-sensing technology for smooth, multi-function control. An ergonomic operator cab provides comfort during extended work periods, while the dual-mode transmission offers both standard and creep modes for precise grading operations. The G990 represents a reliable, purpose-built platform engineered for optimal weight-to-power balance, ensuring maximum productivity and durability in road construction and heavy earthmoving operations.
