  • View product Download


  • 953K uses 10-25 percent less fuel per hour than the previous model.*
  • Optional Performance Series bucket helps you move up to 10 percent more material per hour.
  • Efficient use of Diesel Exhaust Fluid(1)
     - typically 2.5-3 percent of fuel consumption
     - provides excellent overall fluid efficiency.



  • Smoother implement and steering response, and improved steering performance over the previous model.*

  • Features like load sensing hydraulics and position sensing cylinders offer precise, responsive performance.

  • Cat C7.1 ACERT™ engine delivers power and fast response when the machine is under load.

  • Reduced engine noise*
     - quieter for the operator and others around the work site.



  • Steel track undercarriage allows you to work in wet, soft, or sensitive underfoot conditions.

  • Finish jobs in less time
     - track loaders can often start the job earlier and work longer than other machines due to their lower ground pressure and increased traction.

  • Quick Coupler Ready
     - Fusion™ Quick Coupler option allows easy use of forks, buckets, etc. from wheel loaders and other Fusion compatible machines.

Ease of Operation


  • Choose either joystick or two-lever implement controls to match operator preference or application.

  • Speed/steering controls available as either a joystick or as V-lever and foot pedals.

  • Updated cab offers operator comforts like suspension seat, adjustable armrests and controls, and an improved air conditioning system.

  • Excellent visibility to the bucket and all around the machine enhances safety and helps operators work more confidently.

  • Handles and steps help operators climb on and off the machine more easily, from the front or the back of the tracks.

  • Set implement response
     - fine, normal, coarse
     - to match operator preference or application.

  • Emissions reduction technology(1) is designed to be transparent to the operator.



  • Integrated diagnostics show operators on-board pressure readings for faster service.

  • Tilt cab and convenient service access points for easier maintenance and repair.

  • Demand fan provides efficient cooling plus easy fold-down service access.

  • Remote monitoring with Product Link™/VisionLink® helps you manage your fleet more effectively and profitably.
