MAULDIN MG622 MOTOR GRADERS

Technical Description

The Mauldin MG622 is a compact articulated motor grader engineered for precision road maintenance and construction applications. Powered by a turbocharged and aftercooled diesel engine producing 133 horsepower and 363.3 lb-ft of torque, it delivers reliable performance across diverse grading tasks. The machine features a 12-foot moldboard with a maximum cutting depth of 23.5 inches and 31.3 inches of left side shift capability, providing operators exceptional blade control and maneuverability. Its hydrostatic transmission offers two forward and two reverse gears with a maximum speed of 22 mph in both directions, enabling efficient mobility across job sites. The grader's compact footprint—27.4 feet in overall length and 8.4 feet in width—facilitates access to tight work areas, while its 54-inch diameter circle with 14.1 inches of maximum lift above ground ensures enhanced blade positioning flexibility. Weighing 22,840 pounds at full operating capacity, the MG622 maintains a well-balanced weight distribution with 6,695 pounds on the front axle and 16,145 pounds on the rear axle, optimizing traction and stability. The front axle provides 30 degrees of total oscillation and 20 degrees of wheel lean for superior terrain adaptation. Its 24-degree articulation angle and 20.5-foot turning radius enable precise maneuvers in confined spaces. Operating specifications include a 40-gallon fuel capacity and 25-gallon hydraulic system, powered by a 12-volt electrical system designed for extended operational reliability.
