The Cat M Series 3 motorgraders — 12M3, 140M3, 160M3 and their all-wheel-drive (AWD) counterparts — bring the latest emissions reduction technology, greater fuel efficiency, more operator comfort and safety features, as well as enhanced serviceability. M Series 3 motorgraders meet U.S. EPA Tier IV Final/EU Stage IV emission standards.

Fuel Efficiency and Emissions Reduction

M Series 3 motorgraders meet U.S. EPA Tier IV Final/EU Stage IV emission standards using emissions reduction technology that is designed to be transparent, with no action required by the operator. There is no need to stop for regeneration. The system uses Caterpillar's aftertreatment solution with the addition of selective catalytic reduction (SCR). SCR utilizes diesel exhaust fluid (DEF), which can be conveniently filled from ground level when the machine is fueled. Because of improved fuel economy over Tier IV Interim and efficient use of DEF, M Series 3 motorgraders deliver excellent overall fluid efficiency, according to the manufacturer.

A new standard economy (ECO) mode can be turned on to help save fuel by reducing engine speed so the machine works in a more efficient range. The average fuel savings is up to 10 percent, depending on the application.

Integrated Technologies

Cat Connect makes smart use of technology and services to help improve job site efficiency. M Series 3 motorgraders are equipped with Product Link, which helps fleet owners track location, hours, fuel usage, productivity, idle time, and diagnostic codes through the online VisionLink interface.


M Series 3 machines also offer optional grade technologies like Cat grade control cross slope and Cat AccuGrade help operators work more efficiently, productively and accurately.

Comfort and Convenience

In the cab, operators will find the hallmark Cat motorgrader controls — two electronic joysticks that reduce arm movement by 78 percent to help lessen operator fatigue and enhance productivity. M Series 3 models also feature a redesigned message display located in the center console of the machine. The display puts Cat grade control cross slope information conveniently in front of the operator, and also includes a DEF tank level gauge. Operators also will enjoy a more comfortable seat with heated and ventilated options, an optional seat belt indicator light, and several convenient new storage bins located throughout the cab. An additional convenience feature can be found in the engine compartment. New optional LED lights make it easier to service the machine in low light conditions.
