KOMATSU GD825A-2 MOTOR GRADERS

The Komatsu GD825A-2 motor grader features a turbocharged Komatsu S6D140E 6-cylinder diesel engine delivering up to 280 hp (209 kW) at 2100 rpm, optimized for high torque and fuel efficiency. It operates with a Komatsu HYDROSHIFT transmission offering 8 forward and 8 reverse gears, enabling maximum speeds of 27.9 mph (forward) and 29.8 mph (reverse). The machine’s overall length is 32.9 ft with a wheelbase of 23.4 ft and a width of 10.9 ft over tires sized 23.5 X 25-12PR (L3). It weighs approximately 58,250 lbs operating total weight, with front and rear axle loads of roughly 17,570 lbs and 40,680 lbs respectively. The grader’s 16.2 ft long moldboard is 31 in high and 1 in thick, capable of a maximum lift of 19 in above ground and a cutting depth of 19 in, with blade tip angles adjustable to 49° front and 5° rear. It offers a maximum shoulder reach of 7.9 ft outside the rear tires on both sides and outputs a blade pull force of 30,250 lbs. The circle has a 70 in diameter with full 360° rotation, supported by double-acting piston-type hydraulic cylinders operating at a relief pressure of 3560 psi. Hydraulic and fluid capacities include a 132.1-gallon fuel tank, 21.1 gallons for hydraulics, 16.7 gallons for final drive, and 50.2 gallons per tandem housing. The front frame measures 1.4 ft in height and 1.2 ft in width, with a ground clearance of 2.3 ft and articulation steering angle of 25°. The operator’s cab height is 11.7 ft, designed for comfort and visibility with electronic monitoring and robust safety features. This machine is engineered for durability, efficiency, and operator ergonomics suited for heavy-duty grading tasks in challenging environments.
