Caterpillar announces the new, seven-model lineup of M-Series motor graders. The new machines feature a number of concepts in motor grader design—most notably a pair of joysticks replacing as many as 15 levers and a steering wheel. Because of the many control inputs required and the precision work performed by motor graders, they are widely regarded as the most difficult of all earthmoving machines to operate. Caterpillar designed the M-Series joystick control system to make the motor grader easier to learn and less fatiguing.
The M-Series design didn’t stop at the operator station. New features include dynamic styling that opens up lines of sight, easy adjustment of the drawbar, circle and moldboard, a high-torque all-wheel-drive system, enhanced power management and emissions-compliant Cat C-Series engines with ACERT technology.
