The Caterpillar 120M2 and its all-wheel-drive (AWD) counterpart, the 120M2 AWD, are equipped with low-emitting, fuel-efficient engines meeting Tier 4 Interim emission standards and are designed for a broad range of tasks, including heavy blade work, road maintenance, snow removal and precision-finishing.
The new M Series 2 models are powered by Cat VHP (variable horsepower) engines with ACERT technology and all have wider net-horsepower ranges than their M Series predecessors. The 120M2 and 120M2 AWD use the C7.1 ACERT engine. Maximum net power ratings for the new models, respectively, are 189 hp and 209 hp. Operating weight when typically equipped is 39,892 lbs., and 41,859 lbs. The blade width is 12 inches standard.
Variable horsepower plus (VHP Plus) is now standard on the full line-up of M Series 2 machine models, delivering additional horsepower in each forward gear 5th through 8th for more power at higher speeds. The system limits horsepower in lower gears, which helps reduce wheel slip where traction is limited. This optimizes rimpull in all gears by balancing traction, speed, and horsepower while conserving fuel.
The engines utilize the Cat NOx Reduction System and Caterpillar-designed aftertreatment technologies to meet Tier 4 Interim emissions standards. The Cat Regeneration System is designed to work transparently, without any interaction needed from the operator. A soot level monitor can be viewed on the Cat Messenger screen and regeneration indicator lights are integrated into the front console.
The new M Series 2 models continue to feature Caterpillar's control system, which uses two electronic joysticks designed to reduce hand and wrist movement by nearly 80 percent, compared with conventional controls.
The new motor graders also feature electronic vertical adjustment of the joystick control pods, allowing operators to tailor joystick height for optimum control and comfort. The M Series 2 cab, with standard air conditioning, uses angled doors and a patented sloping rear window to afford excellent visibility to the heel and toe of the moldboard and to the ripper.
M Series 2 motor graders offer:
- Revolutionary cab and controls enhance operator comfort and productivity.
- Serviceability features offer ease of maintenance, as well as the ability to quickly adjust the drawbar, circle and moldboard for precise material control and reduced operating costs.
- Electro-hydraulics enable advanced machine control with precise and predictable movements.
- Standard Automatic Differential Lock unlocks the differential during a turn, re-locks when straight, for easier operation and lower power train protection.
- All-Wheel Drive models offer precise control and increased power for improved performance in a variety of applications.
All M Series 2 models feature the new Cat Grade Control Cross Slope system. Cat Grade Control is a complete machine control and guidance system that is fully integrated with standard machine components at the factory. This optional factory-installed and calibrated cross slope system provides automatic cross slope control capability, ready to operate from the moment it leaves the factory. In addition, Cat Cross Slope is fully upgradeable and compatible with AccuGrade systems to grow with customers. The M Series 2 motor graders will also continue to offer the AccuGrade Ready Option which provides all the mounting hardware, controls and harnesses for easy installation of all AccuGrade kits.
Motor grader users can also utilize Cat Product Link, which allows remote monitoring of equipment to improve overall fleet-management effectiveness. Product Link is deeply integrated into machine systems. Events and diagnostic codes, as well as hours, fuel, idle time and other detailed information are transmitted to a secure web based application, VisionLink. VisionLink includes powerful tools to convey information to users and dealers, including mapping, working and idle time, fuel level, and more.
