The Cat M Series 3 motor graders — 12M3, 140M3, 160M3 and their all-wheel-drive (AWD) counterparts — offer greater fuel efficiency, more operator comfort and safety features, as well as enhanced serviceability.
M Series 3 motor graders meet final Tier 4 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 after-treatment solution with the addition of Selective Catalytic Reduction (SCR). SCR utilizes Diesel Exhaust Fluid (DEF), which can be filled from ground level when the machine is fueled.
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%, depending on the application.
