CAT 772GP MOTOR GRADERS

Technical Description

The 2010 CAT 772GP Motor Grader is a heavy-duty, all-wheel-drive machine engineered for precision grading and demanding construction applications. It features a robust 14 ft moldboard with a height of approximately 24–27 inches, a thickness of 0.87–1 inch, and an arc radius of about 16.3 inches, providing excellent material handling and cutting capacity. The blade offers a maximum depth of cut between 28.1 and 30.5 inches, with side shift capabilities of up to 26 inches left and 20.2 inches right, and tip angles of 40° forward and 5° backward for versatile grading. The hydraulic system is closed-center, utilizing a variable piston pump and parallel circuit for responsive, efficient blade control. The grader is powered by an engine delivering 176–270 hp at 1800–2200 rpm, with a 360° blade rotation circle and ground clearance ranging from 13 to 17 inches. Front steering reaches up to 47.5°, with a frame steering angle of 20° left or right, and the front axle provides 18° lean and 32° total oscillation for superior stability on uneven terrain. The transmission typically offers 6 forward and 3 reverse gears, and the machine weighs between 19,000 and 37,000 lbs depending on configuration. Standard control systems include differential lock and throttle lock for enhanced traction and operator convenience. Tire size varies by model, commonly 17.5R25 or 14x24.
