Air Conditioning System
Air ConditioningThe air conditioning system on this machine contains the fluorinated greenhouse gas refrigerant R134a (Global Warming Potential = 1430). The system contains 2.0 kg (4.4 lb) of refrigerant which has a CO2 equivalent of 2.860 metric tonne (2.76 ton).

  • 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.

  • 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.

  • 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.

  • 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.
  • shimless Moldboard Retention System Uses Vertical And Horizontal Adjusting Screws To Keep Moldboard Wear Strips Aligned For Reduced Blade Chatter And Precise Blade Control.
