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.

One Machine, Many Jobs

  • Largest track loader in the industry provides the power, breakout force and capacity to take on tough construction utility, forestry and quarry jobs.
  • Track loader power, traction and agility mean you can use one machine and one operator to do everything from clearing the site to installing utilities and finishing around buildings.
  • Fusion™ Quick Coupler option lets you make fast attachment changes with a wide range of tools like forks, buckets, etc. from wheel loaders and other Fusion compatible machines.
  • Bucket/tooth, undercarriage, track shoe and attachment choices help you equip your machine for optimal performance in your applications.
  • Purpose-built Waste Handler, Low Ground Pressure (LGP), Ship Hold and Steel Mill configurations stand up to the toughest tasks.

Top Performer


  • 973 uses up to 10% less fuel per hour than the previous model.

  • Larger fuel tank means you can work longer before refueling.

  • Automatic, Eco and Power modes match performance to the job for optimal efficiency.

  • Performance Series bucket option boosts productivity up to 20% compared to General Purpose bucket.

  • Cat Payload* technology delivers precise bucket load information with on-the-go weighing. More accurate loading reduces cycle times to help save time, labor and fuel costs.

  • Advansys™ bucket tips are built to give you maximum productivity and the lowest bucket lifecycle cost for your toughest applications.

  • Smoother implement and steering response, and improved steering performance provide more controllability.

  • Load sensing hydraulics and position sensing cylinders offer precise, responsive performance.

Easy to Operate


  • Comfortable cab and an intuitive 10-inch (254 mm) touchscreen dash display help make the job easier.

  • Standard High Definition rearview camera shows prominently in the main display.

  • Slope Indicate helps make operation easier by showing machine mainfall and cross slope right on the display.

  • Enjoy operator comforts like suspension seat and adjustable armrests and controls.

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

  • Speed/steering control choices include either a joystick or a v-lever and foot pedals.

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

  • Emissions reduction technology (when equipped) is designed to work in the background, with no action required from the operator.

Versatility Out Front


  • Maximize your track loader versatility with a broad selection of Work Tool attachments to help you take on just about any task.

  • Fusion Quick Coupler option lets you make fast attachment changes with a wide range of tools from wheel loaders and other Fusion compatible machines.

Focus on Safety


  • 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.

  • Standard rear vision camera enhances visibility behind the machine.

  • Seat belt indicator gives an alarm and registers fault code through Product Link if the operator fails to buckle up, enhancing job site safety.

  • Ergonomics, a quiet engine and low-effort controls help lessen fatigue, so operators are better able to remain fresh and focused.

Equipped for the Job

  • Equip your loader from the factory to take on extra-challenging tasks like soft footing, waste handling, ship hold and steel mill work.
  • For added flotation and traction, or work in more sensitive ground conditions, choose a Low Ground Pressure (LGP) loader with wider tracks.
  • Waste Handler configuration is a versatile machine for loading, sorting, excavation and spreading cover, and 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. Enhanced Cleaning Package reduces cleaning time, adds machine protection and increases compaction.
  • Traction, high reach and machine balance make track loaders ideal for working in ship holds and port handling duties. Specialized guarding and seals help protect the machine, while attachments like coal buckets and trim blades help you get the job done.

Handle the Heat

  • Factory-designed and installed features equip your 973 track loader for the extreme heat and harsh conditions of steel mill work.
  • Maneuverability, visibility and the breakout force needed for fast cycle times make crawler loaders a rugged and efficient choice for handling slag.
  • Specialized heavy duty guarding, insulation, thermal deflectors and high temperature seals throughout the machine.
  • Steel mill cab with heavy duty, laminated windshield glass and steel roof plate.
  • Insulated Steel Mill fuel tank.
  • Welded side bars reduce thermal distortion of the track roller frame.
  • High capacity slag bucket features thicker structures and stronger teeth/cutting edges for longer service life.

Steel Mill Operating Recommendations: Caterpillar recommends that Steel Mill machines be exposed to hot slag for less than 15 minutes each hour to allow for adequate cooling time between cycles. Typically, two machines per furnace and a backup machine for the site provide the best uptime. The timing, frequency and duration of the work and cooling cycles varies by job site, but exceeding the recommended exposure time will prevent the machine from meeting expected performance levels.

Save on Maintenance

  • Designed to help you take care of routine maintenance and get back to work.
  • Grouped service points located behind large access doors.
  • Daily grease points in easy reach at ground level.
  • Service mode in the operator display shows hydrostatic and implement pressure for easier troubleshooting and servicing.
  • Demand fan provides efficient cooling plus easy fold-down service access.
  • Handy bracket holds a shovel for quick undercarriage clean-out.
  • Tilt cab and convenient service access points for easier maintenance and repair.
  • Diesel Particulate Filter in the Clean Emissions Module (when equipped) designed to work for the life of the engine without needing to clean or replace the filter.

Connect to Greater Efficiency

  • Product Link™ collects machine data that can be viewed online through web and mobile applications.
  • Access information anytime, anywhere with VisionLink® and use it to make informed decisions that boost productivity, lower costs, simplify maintenance, and improve safety and security on your job site.
  • The Cat App helps you manage your assets, at any time, right from your smartphone. See fleet location and hours, get critical required maintenance alerts, and even request service from your local Cat dealer.
  • Remote Troubleshoot saves time and money by allowing your Cat dealer to perform diagnostic testing remotely.
