CAT 140M3 AWD MOTOR GRADERS

Technical Description

The 2019 CAT 140M3 AWD Motor Grader is a high-performance, all-wheel-drive machine engineered for demanding grading tasks. It features a Cat C9.3 ACERT engine with a displacement of 9.3 liters, delivering up to 200 hp (149 kW) at 2,000 rpm and meeting U.S. EPA Tier 4 Final/EU Stage IV emissions standards. The advanced hydraulic system uses a variable piston pump, providing up to 55.7 gal/min (210 L/min) flow and a maximum system pressure of 3,500 psi (24,150 kPa), ensuring responsive and efficient implement control. The closed-center, load-sensing design allows for precise operation of up to five hydraulic circuits. Joystick controls manage steering, articulation, blade lift, circle drive, and other functions, enhancing operator comfort and productivity. The transmission is an 8F/6R powershift with direct drive and Advanced Productivity Electronic Control Strategy (APECS), enabling smooth gear changes and optimal performance. The articulated frame offers a 50° steering range, while the AWD system provides superior traction on challenging terrain. Standard features include an automatic differential lock, oil-cooled multi-disc brakes, and a hydraulic demand fan for improved cooling and fuel efficiency. The machine has a typical operating weight of 45,917 lb (20,827 kg), a 12 ft (3.7 m) blade width, and a top forward speed of 29 mph (46.6 km/h). The 140M3 AWD is designed for durability, ease of service, and operator safety, making it ideal for a wide range of construction and maintenance applications.
