The range of Cat® M Series Motor Graders is well suited to the work you need to get done in a variety of heavy construction, governmental and mining/haul road applications.

Cat® M Series Motor Graders Highlights

  • Revolutionary joystick controls reduce hand & wrist movement by 78% so your operators can work more comfortably and productively shift after shift.
  • Angled doors, tapered floor and no levers in front give you a clear line of sight to the blade and around the machine.
  • Drawbar-Circle-Moldboard components are designed to significantly reduce adjustment time so it’s easy to maintain factory-tight components for your highest quality work.
  • Cat Grade Control Cross Slope is a factory-integrated option that helps you achieve first-pass accuracy by automating one end of the blade.
  • Every Cat Motor Grader is designed with the safety of people in mind, with features like redundant steering and brake systems, remote engine shutdown switch, implement lockout, an optional rearview camera and so much more.
  • M Series 2 models meet U.S. EPA Tier 4 Interim/EU Stage IIIB emission standards.

Engine

Caterpillar engines handle tough loads. Variable Horsepower matches torque curves, maximizing response, power and efficiency. Low fuel consumption minimizes operating costs.

Power Train

Power shift transmissions take advantage of powerful Caterpillar engines. Variable Horsepower uses specific torque curves for optimum performance. Dual air system and multi-disc oil brakes assure braking control.

Hydraulics

Load-sensing hydraulic systems lower power consumption and system heat. Advanced PPPC valves provide low lever effort, balanced flow and consistent cylinder speeds for blade control. Blade float is in the blade lift valves.

Drawbar, Circle and Moldboard

Moldboard position and long wheelbases improve handling. Rugged construction and replaceable parts minimize operation costs.

Structures

Motor grader frames are built to exceed customer expectations.

Operator’s Station

Low effort controls, electronic throttle control, EMS III monitoring system and improved ventilation provide operator control and comfort. Improved visibility increase operator confidence and productivity.

Serviceability

Re-engineered inspection and service points are grouped in to convenient ‘service centers.’ Ground-level fueling and longer engine and hydraulic oil change intervals help minimize downtime.

Environmentally Responsible Design

Engine and cab designs reduce emissions to meet anticipated regulations for sound levels, emissions and exhaust.

Customer Support

Cat dealers offer services to help you operate longer with lower costs.
