CATERPILLAR 12M2 MOTOR GRADERS

The 2013 Caterpillar 12M2 Motor Grader features a powerful Cat C9.3 ACERT™ engine delivering approximately 173 hp (129 kW) with displacement of 9.3 L and a bore and stroke of 4.5 in and 5.9 in respectively. It offers a direct drive power shift transmission with 6 forward and up to 6 reverse gears, enabling a top travel speed of up to 29 mph. The grader operates at an operating weight near 42,383 lbs, supporting a 12-foot wide moldboard capable of 360-degree blade rotation, with blade tip angles of 40° forward and 5° backward. Its hydraulic system is a closed-center, variable displacement piston pump providing around 55.7 gal/min flow at up to 3,500 psi pressure for precise implement control. Steering includes front axle articulation up to 20° with a maximum steering angle around 47.5°, allowing a tight turning radius near 24 ft 10 in. The machine maintains about 2.1 ft ground clearance and rides on tire sizes such as 14x24. Safety and ergonomics are enhanced by features such as joystick controls with brake tensioning, integrated brake wear indicators, and an operator presence system disabling hydraulic implement functions when the operator is absent. The 24V electrical system supports up to 150 amps alternator output. Fuel capacity varies but is typically around 18 to 130 gallons depending on configuration. This model meets Tier 4 Interim/Stage IIIB emissions standards, ensuring efficient performance with reduced environmental impact, suitable for demanding grading applications requiring robust power and precise control.
