Air Conditioning System

Air Conditioning
The air conditioning system on this machine contains the fluorinated greenhouse gas refrigerant R134a (Global Warming Potential = 1430). The system contains 1.1 kg of refrigerant which has a CO2 equivalent of 1.573 metric tonnes.


  • 963K uses 10–25 percent less fuel per hour than the previous model.
  • Efficient use of Diesel Exhaust Fluid*– typically 2.5-3 percent of fuel consumption – provides excellent overall fluid efficiency.
  • Optional Performance Series bucket helps you move up to 5 percent more material per hour.
  • 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.

    * Machine equipped with U.S. EPA Tier 4 Final/EU Stage IV emissions reduction technology.


  • 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 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.


  • 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 is designed so regeneration runs automatically in the background while you work.


  • 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.


  • Waste Handler arrangements feature added guarding and seals to give you a purpose-built machine to take on the challenges of waste applications. A choice of buckets and track shoes allow you to further optimize the machine for greater performance and service life.
  • Versatile machine for loading, sorting, excavation and spreading cover, well suited to the landfill or transfer station.
  • Specialized guarding, striker bars and seals help protect the machine and components from impact and airborne debris.
  • Final Drive guarding helps prevent wrapping and damage.
  • Bars help protect windshield and operator from breakage and debris. Cab door guards offer added protection.
  • Cooling system is designed for high debris environments and easy cleanout access.
  • Specialized air handling features help deliver cleaner air to the machine and to the cab.
  • Laminated thermal shields and insulated clean emission module.
  • Landfill buckets, equipped with heavy-duty trash rack, offer increased capacity and reduced spillage.
  • Center-hole track helps reduce packing. Choose from a variety of shoe types and widths to optimize the loader for your application.
  • Optional rear vision camera enhances visibility behind the machine.
  • Enhanced Cleaning Package -
  1. Faster, easier cleanout.
  2. Wide gauge undercarriage equipped with a standard track shoe allows more space for debris to pass between the track roller frame, tracks and chassis.
  3. Design helps reduce damage caused by debris carried on the tracks.
  4. Heavier waste configuration combined with narrower track shoes increases ground pressure for greater compaction.

    Note: Features may vary by model and region. Please consult your Cat dealer for details and availability.


  • Specialized Ship Hold machines give you the optimal combination of traction, high reach and machine balance makes track loaders ideal for working in ship holds and port handling duties.
  • Specialized implements, like coal buckets and trim blades, help you sweep down walls and handle a variety of materials.
  • Fusion Quick Coupler option adds versatility with easy use of forks, buckets and other attachments from compatible machines.
  • Specialized sealing, guards and bumpers help protect key components.
  • Front and rear eyes widely spaced for stability during lifting.
  • Added lighting packages help illuminate the work area.
