The Caterpillar 140M2 is a motor grader designed for road construction, maintenance, and grading applications. It is part of Caterpillar's M Series lineup and is used for shaping surfaces, spreading material, ditching, and fine grading on highways, municipal roads, and job sites. The 140M2 typically features a front-mounted engine, articulated frame, and centrally located moldboard for improved control and visibility. It is commonly equipped with a diesel engine, powershift transmission, and hydraulic controls for blade positioning. The model is used in earthmoving, site preparation, and snow removal operations where precise grading performance is required.
