  • Optional Stable Blade improves grading precision by decreasing engine speed at 15 percent intervals when machine bounce is detected then increases engine rpm systematically when grader stabilizes.
  • Optional Cat Grade with Cross Slope helps maintain desired cross slope by automatically controlling one side of the blade.
  • Optional Cat Grade uses positioning and guidance technologies, machine sensors, and automatic blade control to help get to grade faster, easier, and more efficiently.
  • Optional Auto Articulation allows you to articulate automatically while steering in tight spaces or around curves, obstacles, and turnarounds.
  • Manage your fleet of machines while reducing fuel burn with Cat Production Measurement System option. The Efficiency Coach and Application Segmentation work together to monitor operators and machines simultaneously. Measure your jobsite’s efficiency and productivity from anywhere on the website.


  • Cat C13 engine meets U.S. EPA Tier 4 Final/EU Stage V, Tier 3/Stage IIIA equivalent or Tier 2/Stage II equivalent emission standards, depending on emission standards of specific country.
  • Standard Economy Mode can be turned on to limit maximum engine speed which helps reduce fuel consumption.
  • Standard VHP Plus provides ideal amount of power in all gears.
  • Standard Automatic Differential Lock unlocks differential during a turn and re-locks when straight for easier operation and improved power train protection.


  • Load-sensing system and advanced electro hydraulics give operator superior implement control and hydraulic performance.
  • Proportional Priority Pressure-Compensating valves have different flow rates for head and rod ends of cylinder so machine responds consistently and predictably.
  • Balanced hydraulic flow is proportioned to ensure all implements will operate simultaneously without slowing engine or speed of some implements.


  • Simple, intuitive joystick controls replace levers, so hand and arm movement is reduced by 78%, helping reduce operator fatigue.
  • Optional Advanced Control Joysticks allow operator to control automated grading solutions efficiently and safely without removing hands from the joysticks.
  • Selectable blade lift modes
     - Fine, Normal, or Coarse
     - allow operator to match application requirements.
  • Articulation Return-to-Center automatically returns machine to a straight frame position from any angle with the touch of a button.


  • Optional rear vision camera enhances sight to rear of machine.
  • Electrical disconnect and engine shutoff switches are ground level.
  • Operator Presence System keeps parking brake engaged and hydraulic implements disabled until operator is seated and machine is ready for operation.
  • Hydraulic Lockout disables all implement functions while still providing machine steering control
     - especially useful while roading.
  • Optional seat belt indicator promotes safe operating habits.


  • Convenient access from the top of the circle to the patented top-adjust wear strips and inserts make them easy to add or replace.
  • Shim less Moldboard Retention System uses vertical and horizontal adjusting screws to keep moldboard wear strips aligned for reduced blade chatter and precise blade control.
