The Champion C66C is a compact single-axle motor grader powered by a Cummins 4BT3.9 turbocharged diesel engine delivering 110 net horsepower at 2500 rpm in first gear, with a four-cylinder displacement of 238 cubic inches. The machine features a hydrostatic transmission enabling forward and reverse speeds of 19.9 mph, with an operating weight of 13,404 pounds, making it highly maneuverable for confined work spaces. The moldboard measures 10 feet in width and length with 0.7-inch thickness, providing a 10-foot cutting width for grading operations. The redesigned C Series front axle incorporates 50 degrees of steering angle left and right—a 15-degree improvement over previous models—enabling 360-degree turns within a 17-foot 6-inch circle. The machine achieves a ground clearance of 22 inches with the front axle raised 6 inches, allowing superior obstacle clearance. Blade specifications include 45-degree front and 5-degree rear tip angles, with maximum reach of 75 inches outside the tires and 44-inch moldboard sideshift capability. The cab height measures 9.1 feet, overall length is 20.9 feet, and tire width is 7.2 feet. The front axle provides 35 degrees total oscillation and 15 degrees wheel lean for enhanced terrain adaptation. Enhanced blade lift arrangement delivers over 35 percent increased blade lift stance to a full 4 feet across.
