CATERPILLAR 140 AWD M3 MOTOR GRADERS

Technical Description

The 2018 Caterpillar 140 AWD M3 Motor Grader is a robust machine powered by a 250 hp net, 270 hp gross six-cylinder Cat engine with a displacement of 567 in³, delivering maximum torque of 868 lb-ft. It features an all-wheel-drive system with an operating weight of approximately 44,614 lb, distributed with 14,682 lb on the front axle and 29,932 lb on the rear axle. The grader spans 29 ft 5 in in overall length, 8 ft 5 in in width over tires, and stands 11 ft 3 in tall to the top of the cab, with a ground clearance of 13.9 inches and a wheelbase of 20 ft 4 in. The machine is equipped with a 12 ft wide blade (moldboard) that is 24 in in height and 0.87 in thick, capable of lifting 17.1 in above ground and digging 6.5 in below ground. It provides a substantial blade side-shift range of 20.7 in left and 26.1 in right, with a circle diameter of 60.2 in for blade rotation. The articulation angle is 20°, front wheel lean is 18°, and steering angle is 50° left and right, ensuring excellent maneuverability. Performance-wise, it achieves a top forward speed of approximately 28 mph and reverse speed of around 20 mph. Its hydraulic system includes a pump capacity of about 55 gal/min operating at a maximum system pressure of 3,500 psi. Fuel capacity is approximately 110 gallons, with cooling system capacity of 15 gallons, hydraulic fluid capacity of 20 gallons, engine oil capacity near 7.9 gallons, and transmission/differential/final drive capacity totaling 20 gallons. This combination of power, precision, and hydraulic efficiency makes the 140 AWD M3 suited for demanding grading tasks.
