The new Cat M Series 3 motor graders—12M3, 140M3, 160M3 and their all-wheel-drive (AWD) counterparts—bring the latest emissions reduction technology to the most durable, productive and comfortable graders on the market. The new models offer greater fuel efficiency, more operator comfort and safety features, as well as enhanced serviceability. M Series 3 motor graders meet U.S. EPA Tier 4 Final/EU Stage IV emission standards.
M Series 3 motor graders meet U.S. EPA Tier 4 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 proven 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 4 Interim and efficient use of DEF, M Series 3 motor graders deliver excellent overall fluid efficiency.
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.
In the cab, operators will find the hallmark Cat motor grader controls—two electronic joysticks that reduce arm movement by 78% 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 will also 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.
