The Komatsu GD200A-1 motor grader is a versatile construction machine designed for precise grading and earthmoving tasks. It features a Komatsu 4D105-5 engine with a displacement of 264 cu in (4.3L), delivering a maximum power output of 65 hp (48 kW) and a net torque of 174 lb-ft in gears 5-6. The grader’s overall length is approximately 18.1 ft (5.5 m) with a wheelbase of 11.8 ft (3.6 m). It has a front ground clearance of 1.6 ft (480 mm) and rear ground clearance of 0.94 ft (285 mm), enabling effective terrain navigation. The machine’s moldboard measures 7.3 ft (2.2 m) in width, 18.9 in (480 mm) in height, and 0.4 in (9 mm) in thickness, with a maximum depth of cut of 8.3 in (210 mm), suitable for diverse grading requirements. The blade base spans 4.5 ft (1.36 m). The front axle allows for a ground clearance of 1.5 ft (430 mm) and oscillates up to 26 degrees, improving stability and adaptability on uneven surfaces. The grader has an articulation angle of 30 degrees and a turning radius of 14.8 ft (4.5 m), providing excellent maneuverability. Operating weight totals approximately 11,244 lbs (5,100 kg), distributed as 3,075 lbs (1,395 kg) on the front axle and 8,168 lbs (3,705 kg) on the rear axle. Tires are sized 7.50-20-10PR at the front and 42x17-20-10PR at the rear. The transmission includes 5 forward and 5 reverse gears, allowing maximum forward and reverse speeds of 19.4 mph (31 kph) and 17.9 mph (28 kph) respectively. The circle assembly offers a maximum lift above ground of 10.7 in (270 mm) with reach outside tires of 22.9 in (580 mm) left and 19.7 in (500 mm) right.
