CATERPILLAR 140M2 MOTOR GRADERS

Technical Description

The Caterpillar 140M2 is a versatile motor grader powered by a Cat C9.3 ACERT engine delivering 193–243 hp across eight forward gears, meeting U.S. Tier 4 Interim/EU Stage IIIB emission standards. The machine features a 12-foot moldboard with exceptional blade control capabilities, including 360-degree circle rotation, 90-degree maximum blade angle positioning, and 28.1 inches of maximum cutting depth. The moldboard provides 27.4–28.7 inches of centershift and 20.1–26 inches of sideshift for precise material placement and shoulder reach extending to 77.9 inches outside the tires. Operating at 2,100 rpm, the engine produces 920 lb-ft of maximum torque with superior lugging capability for consistent grading speeds without downshifting. The hydraulic system utilizes a variable piston pump delivering 55.7 gpm at 3,500 psi maximum pressure through a parallel circuit configuration, enabling responsive blade control and efficient operation. Measuring 29.2 feet long, 8.5 feet wide, and 10.8 feet tall with a 20.1-foot wheelbase, the grader achieves speeds up to 29 mph forward and 22.9 mph reverse with eight forward and six reverse gears. The articulated frame articulates 20 degrees with a 25-foot turning radius, while front oscillation of 32 degrees accommodates uneven terrain. The typically equipped operating weight reaches 43,686 pounds, distributing approximately 12,483 pounds on the front axle and 31,203 pounds on rear tandems. Optional ripper and scarifier attachments provide additional versatility for soil preparation and ripping operations with penetration forces reaching 20,693 pounds.
