Technology

  • 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 AccuGrade™ 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.

Performance

  • Cat C13 ACERT™ engine meets U.S. EPA Tier 4 Final/EU Stage IV, 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.

Efficiency

  • Load-sensing system and advanced electrohydraulics 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.

Ease of Operation

  • 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.

Safety

  • 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.

Serviceability

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