  • 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

  • Leading in class manufacturing and quality control level, mandatory  performance testing before delivering to MG assembly line

  • 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

  • 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.
