Product Description(Motor Grader)

Large Cab

  • High performance dashboard with 3 levels alarming monition system.
  • Cab mounted on the front frame provides exceptional view to blade and front axle even during articulation.
  • Large cab with 1.9m height and 30% larger space than most competitors, provides exceptional Comfort.

SEM Tandem Axle

  • Leveraging Caterpillar designing and experience on MG tandem axle.
  • Improved bearing Layout and optimized load distribution with 4 planetary gears final drive.
  • Less down time and reduced labor and service cost for maintenance and repairing.
  • Longer service interval for lubrication oil change.

Control System

7 position link bar with electric over hydraulic control allows ease of operation from within the cab.

  • Optimum blade reach capability, quick DCM re-positioning for greater reach for better working on high bank side slope.
  • The link bar is essential for extending reach capability when cutting a bank slope or back slope of a ditch.
  • Replaceable bushings reduce service time and cost.

Blade Float

Standard blade float function allows blade to lower without hydraulic pressure for increased versatility.

  • Blade float is engaged by pushing the left and right lift cylinder controls all the way forward past the detent.
  • Provides protection for machine and pavement during snow removal and snow plowing.

Hydraulic System

  • Proportional Priority Pressure Compensating (PPPC) Valves contain specifically cut spools for motor grader applications, continuously matching of hydraulic flow and pressure to power demands, allowing ease of multi-function control for optimizing working efficiency.
  • World-class variable displacement piston pump, efficiently reduces power consumption and hydraulic system heat, improving fuel efficiency.
  • Load-sensing hydraulic system provides consistent and precise blade movement, improving finishing performance.
  • Inboard lock check valves within PPPC, prevents inadvertent cylinder movement and potential leaks.


  • A-frame tubular design drawbar provides maximum strength and durability.
  • Replaceable drawbar draft ball (bolted – not welded) for less service time and cost.
  • Easy removal of wear shims to adjust drawbar

Front Frame

  • Flanged box section design removes welds from high stress areas, improving reliability and durability.
  • Continuous top and bottom plate construction provides consistency and strength, improving front frame durability.
  • Hydraulic hose routing minimizes exposure to damage and provides quick access for service.
  • Maintenance-free bushings improve durability and reduce overall service cost.

Control Layout

  • Short throw levers are efficiently spaced, allowing ease of multi-function control.
  • Short lever travel (40mm) with low lever effort reduces operator fatigue.

Cat® Product LinkTM

  • Cat® Product Link™ will support your business, and accurately convey information of the equipment to relevant personnel in a timely and effective manner for your better equipment management.
