CAT 140M3 MOTOR GRADERS

Technical Description

The 2019 Caterpillar 140M3 Motor Grader features a powerful Cat C9.3 ACERT 6-cylinder engine with a displacement of 9.3 L, delivering net power ranging from 176 to 196 hp (131 to 147 kW) at 2000 rpm. It employs a robust transmission system with 8 forward and 6 reverse gears, optimized with Variable Horsepower Plus (VHP Plus) for enhanced performance and fuel efficiency. The grader is equipped with 17.5R25 tires, providing excellent traction on various surfaces. The machine's moldboard measures 14 ft in length and 24 in in height, with a thickness of 7/8 in, offering a cutting depth of up to approximately 28.9 in (735 mm) and a maximum depth of cut at 16.1 in when used with the ripper attachment. Blade side shift capabilities allow 26.1 in to the left and 20.2 in to the right, complemented by a blade tip cylinder that enables forward angles up to 40° and backward angles up to 5°. The grader's hydraulic system operates under a closed-center, parallel circuit with a variable piston pump delivering hydraulic output of 24,150 kPa at 1800 rpm, ensuring responsive and precise control. It offers a maximum steering wheel angle of 47.5° and frame articulation of 20°, while the front axle achieves an 18° lean and oscillates 32° total, enhancing maneuverability over rough terrain. The ground clearance at machine center is about 24.1 in (612 mm). Overall, the 140M3 is a durable and versatile motor grader designed for heavy-duty earthmoving and road maintenance operations, with a machine length of approximately 29 ft to 31 ft depending on configuration.
