Performance

  • Programmable Autoshift option simplifies operation by allowing transmission to be programmed to shift at optimal points to match application.
  • Power Shift Countershaft Transmission matches to engine, maximizing power to the ground.
  • Electronic Throttle Control helps improve productivity by providing best match of horsepower and torque for application demands.

Efficiency

  • Aggressive blade angle, optimized moldboard curvature and large throat clearance allow material to roll more freely along blade, increasing efficiency.
  • Hydraulic demand fan automatically adjusts speed according to cooling requirements resulting in more power to the ground and improved fuel efficiency.
  • Engine idle shutdown timer is available to shut down engine after a set period of time saving fuel and helping reduce emissions.

Ease of Operation

  • Selectable blade lift modes – Fine, Normal, or Coarse – allow you to choose the blade lift modulation mode that best fits your application or operating style.
  • Joystick controls with electronically adjustable control pods reduce hand and arm movement by 78%, helping reduce operator fatigue.
  • Left joystick controls steering, articulation, return-to-center, wheel lean, gear selection, left moldboard lift cylinder and float.
  • Right joystick controls drawbar, circle and moldboard functions as well as electronic throttle control and manual differential lock/unlock.
  • Articulation Return-to-Center automatically returns machine to a straight frame position from any angle with the touch of a button.

Safety

  • Angled cab doors, tapered engine enclosure and sloped rear window make it easy to see moldboard and tires, as well as behind the machine.
  • Optional rear vision camera enhances sight to rear of machine.

Serviceability

  • Sacrificial brass wear strips between blade mounting group and moldboard can be easily adjusted and replaced.
  • Shimless Moldboard Retention System uses vertical and horizontal adjusting screws to keep moldboard wear strips aligned for reduced blade chatter and precise blade control.

Comfort

  • Control pods can be adjusted electronically, making it easy to set to ideal operating position.
  • Standard Cat Comfort Series suspension seat is fully adjustable.
  • High capacity Heating, Ventilation and Air Conditioning (HVAC) system dehumidifies and pressurizes cab, sealing out dust and helping keep windows clear.

Technology

  • Shuttle Shift allows smooth, fast direction shifts without requiring you to manipulate the throttle or inching pedal.
  • Cat Product Link™ aids equipment management with remote monitoring capabilities.
  • 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 Auto Articulation allows you to articulate automatically while steering in tight spaces or around curves, obstacles, and turnarounds.
  • 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 Cat Advanced Control Joysticks allow you to control automated grading solutions efficiently and safely without removing your hands from the joysticks.
