NEW HOLLAND RG80 MOTOR GRADERS

The New Holland RG80 motor grader is a robust construction machine designed for precision grading and earthmoving tasks. It features a powerful Genesis 5.0 four-cylinder diesel engine with a displacement of 303.9 cubic inches, delivering 76 horsepower at 2200 rpm and 240 lb-ft of torque at 1400 rpm. The engine's 4.5-inch bore and 5-inch stroke support reliable performance optimized for diverse grading conditions. The grader measures 21.8 feet in overall length, with a width of 7.6 feet over the tires, and a height of 9.9 feet to the top of the isomount cab, offering a compact yet versatile footprint on job sites. The machine’s moldboard is 10 feet wide, 16.4 inches high, and 0.7 inches thick, capable of 360-degree rotation with a circle diameter of 52.8 inches, allowing full maneuverability and precise blade positioning. The front axle provides 1.7 feet of ground clearance, with 20 degrees total oscillation and 18 degrees wheel lean, aiding stability on uneven terrain. Hydraulic power is supplied by a BARNS gear pump with a flow rate of 10.1 gpm and relief valve pressure at 1850 psi, ensuring efficient moldboard control. The grader's weight totals 15,500 lbs, distributed as 4557 lbs on the front axle and 10,943 lbs on the rear, supported by 15.00x19.5 - 8 PR tires. The steering articulation angle is 25 degrees, yielding a tight turning radius of 18.8 feet. Transmission is a torque converter with power shift offering six forward and three reverse gears, with maximum speeds of 25.1 mph forward and 16.5 mph reverse, providing smooth and responsive control across varied job demands. The electrical system operates at 24 volts with a 100-amp alternator. This combination of engine power, hydraulic capacity, and maneuverability makes the RG80 a reliable grader for professional land grading applications.
