CAT 14G MOTOR GRADERS

Technical Description

The 1979 CAT 14G Motor Grader is a robust, articulated-frame machine designed for heavy-duty grading and earthmoving tasks. It features a 16-foot blade with a typical width of 16 feet, a thickness of 1 inch, and a height of 27 inches, providing substantial cutting and leveling capacity. The blade’s arc radius is 16.3 inches, with a throat clearance of 5 inches and end bits measuring 6 inches wide. Powered by a Caterpillar diesel engine, net power is rated around 180 hp at 1800–1850 RPM, with engine displacement typically between 7 and 12.5 liters. Maximum forward speed reaches approximately 31 mph, while reverse tops out at about 24.8 mph. The grader is equipped with a direct-drive, power-shift transmission offering multiple forward and reverse gears, commonly 8F/6R, for efficient operation across varied terrain. Hydraulic systems utilize a closed-center, variable piston pump, delivering roughly 74 gallons per minute at 3500 psi for responsive implement control. Front steering allows up to 47.5° of articulation, enhancing maneuverability, while ground clearance ranges from 13.7 to 28.7 inches. The circle diameter measures approximately 71.7 inches, and maximum depth of cut is around 28–30.5 inches. Operating weight typically falls between 33,000 and 40,000 lbs. The machine is fitted with 20.5-25 inch tires, ensuring reliable traction and durability in demanding conditions.
