The Fuel, Water And Engine Oil Are Relocated At Ground Level On The Right Hand Side Of The Machine For Easy Access.

Have Been Changed From An Air Actuated Drum Shoe Brake To A Hydraulic Actuated Tractor Wet Disc Brake And A Scraper Dry Caliper.

This Feature Will Allow The Machine To Control The Slip Of The Tractor Tires Only.

In The Event Of An Engine Over Speed Situation, The Compression Brake Or Brakes Will Automatically Engage With No Operator Input. The Machine Determines The Over Speed Condition Based On Rate Of Acceleration And Applies Compression Brakes Automatically.

With Similar Technology As The Cat® Advanced Ride Management Seat Suspension, This Software Allows The Cushion Hitch To Prevent End Stroke By Having The Ability To Predict End Stroke Events And Manage The Rate Of Dampening. Resulting In Reduced Hitch Maintenance And Improved Operator Ride In Rough Conditions.

K Series Steering System Design Requires Significantly Less Steering Effort. The Reduced Steering Effort Will Allow For Decreased Operator Fatigue And A More Efficient Operator Resulting In Possible Higher Rates Of Production Late In The Work Cycle.

This Standard Feature Allows The Machine To Prevent The Operator From Engaging The Differential Lock When Damage Could Occur.

The K Series Cab Interior Improves Operator Comfort And Visibility. The Overall Interior Is 21% Larger Than The G Series Cab.

This Feature Is Designed To Take The Place Of Top Gear Selection. If The Machine Top Speed Needs To Be Limited The Operator Can Select The Top Speed Through The Display Or The Top Speed Can Be Set In Et. This Will Allow The Machine To Find The Correct Gear That Works Best For The Engine And Transmission. Allowing The Engine And Transmission To Select The Correct Gear To Pull The Load In Most Cases Resulting In A Lower Engine Load Factor And Lower Fuel Burn Verses Using Top Gear Selection That Required The Machine To Run At Engine Speeds At Or Close To High Idle.

Ground Speed Control Sets The Desired Top Speed By The Operator If Job Site Conditions Or Segment Speed Limits Require A Speed Less Than Full Run Out. Machine Speed Limit Is Intended For Use When Top Speed Needs To Be Limited For Longer Durations And Ground Speed Control Is Intended For Use When The Top Speed Needs To Be Reduced For Shorter Segments Or Intermediate Periods Of Time. The Operator Can Set The Desired Top Speed And The Machine Will Find The Correct Gear That Works Best For The Engine And Transmission.

This Option Uses Cylinder Position Sensors To Automate Bowl, Apron And Further Implement Controls Throughout The Four Core Work Cycles: Dig, Haul, Unload And Return. When Utilized This Can Reduce Up To 14 Individual Operator Commands Per Cycle. Sequence Assist Simplifies Control Over The Implements, Reduces Joystick Usage, Automatically Controls Cushion Hitch, Transmission Hold And Ejector.

The Payload Estimator Will Calculate The Payload Of The Machine In Tonnes Or Tons By Measuring The Bowl Lift Cylinder Pressures At The Beginning Of The Loaded Haul Segment. This Feature Works Best When Using Sequence Assist. Using Payload Estimator During Testing Has Achieved Better Than 95% Accuracy When Compared To Actual Scale Weights. The Payload Estimator Feature Comes Automatically When A Machine Is Ordered With Sequence Assist.

Is Designed To Help Shorten The Learning Curve Of Inexperienced Operators To Ensure Consistency And Faster Loading Of Material While Reducing Effort Of The Operator. Based On The Speed Of The Machine, Load Assist Automatically Adjusts The Cutting Edge Height To Manage Wheel Slip And To Ensure Consistent And Efficient Loading In Bulk Earthmoving Applications.

Intelligently Ensures The Machine Does Not Cut Below Grade In The Cut Area Or Over Fill In The Fill Area – Avoiding Rework And Moving Unnecessary Material.
