Comfort and Ease of Operation
Cab or canopy, the 303C CR offers a spacious and comfortable work area with expansive legroom. Compact radius design gives greater machine versatility and the capability to work within confined areas.
Impressive Cab Dimensions
The CR C Series gives the operator a comfortable and spacious working environment with excellent visibility. The clear flat floor space and superior operator legroom provide high levels of operator comfort and help minimize fatigue.
Optional Air Conditioning
Optional air conditioning or fan and sun blind package offers further operator comfort.
Sliding Cab Door
The sliding door system offers good access and maintains the machine's compact dimensions to reduce the risk of damage.
Fully Pilot Operated Controls
Pilot operated controls on all services including travel levers and dozer function ensure that “as new” levels of controllability are maintained throughout the machine life.
Automatic Two Speed Function
Improves machine maneuverability around the job site. Increased productivity is achieved by balancing high speed travel requirements with controllability.
Joystick Mounted Auxiliary and Boom Swing Functions
The new joystick mounted position of these functions gives “fingertip” control and a clear cab floor.
Compact Radius Design
Compact radius design gives greater machine versatility and the capability to work within confined areas. The radius of the upper body stays within the width of the undercarriage so the operator can concentrate on the work being done without having to worry about the back of the machine.
High Level of Standard Comfort Features
Reclining suspension seat, power point, adjustable wrist rests and a cup holder are standard features on the Cat C CR machines.
Performance and Versatility
High dig forces, fast cycle times and high bucket rotation angles deliver the productivity that customers demand. A choice of stick lengths and Cat Work Tools makes the 303C CR even more versatile.
Fast, Powerful Digging
High digging forces and fast cycle times through smooth responsive hydraulics, ensure that the Cat C Series CR machines deliver the productivity that customers demand.
Load Sensing Hydraulics
Load sensing hydraulics optimize flow for smooth powerful performance and increased fuel economy.
Dozer Blade Float Function
The dozer float enables easy ground levelling for landscaping and finishing applications, as well as more efficient site clean-up.
Stick Options
A choice of standard or long stick enables matching of machine to application.
Hydraulic 'Thumb Ready' Sticks
All Cat CR C Series machines come standard with stick mounted brackets, ready to fit a hydraulic thumb.
Auxiliary Lines and Connectors
The auxiliary lines and connectors including quick connections are fitted as standard, meaning the Cat 303C CR come ready to work. Hammer (one-way) and auger (two-way) auxiliary lines are also fitted as standard.
Mechanical Quick Coupler
The Cat Quick Coupler makes tool changes fast and easy. It maximizes performance as it is compatible with all standard work tools. Work tool versatility is further enhanced with the option of a second additional auxiliary supply.
Wide Range of Work Tools
These tools are designed to get the best out of the machine and deliver excellent value through high productivity and long life. Tools on offer include:
  • Digging buckets
  • Ditch cleaning buckets
  • Angling ditching buckets
  • Hydraulic hammers
  • Augers
Bucket Angle
High rotation bucket angle combines good spoil retention and flat back trench characteristics.
Low Operating Costs
Robust, reliable and easily serviced are key attributes of the C Series CR design. Service points are easily accessed through the rear door and side cover and a 500-hour engine oil change period lowers operating costs.
Swing Out Rear Door
Provides access to major components and service points:
  • Engine oil check and fill
  • Vertically mounted engine oil filter
  • Starter motor
  • Alternator
Lifting Side Hood
Allows excellent access to:
  • Air filter
  • Main implement valve
  • Auxiliary change over valve
  • Accumulator
  • Radiator and oil cooler
  • Fuel filter
  • Hydraulic tank
S•O•SSM Oil Sampling Valve
Allows easy sampling of the hydraulic fluid for preventative maintenance.
500 Hour Oil and Filter Change Period
Reduces operating costs and machine down time.
Front Linkage
Protected front linkage lines are routed above the boom and stick to help reduce damage and downtime.
End Dampening
End dampening on both boom and stick cylinders reduces shock loading, increasing component life and improving soil retention when loading at height.
Liner Bearings
Liner bearings in the swing casting deliver longer component life and reduced parts replacement costs.
Angle Blade Configuration
The versatility and productivity of the Cat C Series machine can be increased even further by ordering the hydraulic angling dozer blade configuration.
Versatility and Productivity
The Cat C Series machine can be increased even further by ordering the angle dozer blade configuration.
Strong and Durable
The Cat hydraulic angle blade is engineered to be strong and durable with a hardened steel wear edge and good protection to cylinders and hydraulic lines.
Single Control Lever
All dozer functions are controlled from inside the cab, with fully proportional fingertip control to position the blade at any angle, from the start to 25 degrees left or right while travelling in either direction.
Full Pilot Control
Full pilot control means no cables or linkages to wear, keeping ”as new” controllability throughout the machines life and reducing maintenance costs.
Angle Blade Positioning
The angle blade can be positioned straight ahead or angled up to 25 degrees to the left or right reducing the number of times required to back-up and reposition when backfilling thus reducing operation time.
Load Sensing Hydraulics, High Traction Force and Auto 2-Speed Travel
These features are standard on the Cat C series CR machines and ideally suited for getting the best out of the angling blade installation.
Excellent Blade Visibility
The compact radius design of the Cat C Series machines gives excellent visibility to the blade in any position, allowing the blade to be positioned behind the operator and away from the front linkage for better access when back dragging and finishing in tight areas.
Customer Support
Caterpillar dealers offer unmatched customer support with excellent equipment management services and fast parts availability, resulting in maximum uptime and minimum repair costs.
Selection
Make detailed comparisons of the machines under consideration before you purchase. Your Cat dealer can give you precise answers to your questions, as well as estimate component life, preventive maintenance cost and the true cost of lost production.
Purchase
Look past initial price. Consider the flexible financing options available, as well as day-to-day operating costs. Look at dealer services that can be included in the cost of the machine to yield lower equipment owning and operating costs over the long haul. Your Cat dealer can provide a package to meet your needs.
Operation
Improving operating techniques can boost your profits. Your Cat dealer has training literature, video tapes, classes and other ideas to help increase your productivity.
Equipment Maintenance Services
More and more equipment buyers are planning for effective maintenance before buying. Choose from your dealer’s wide range of maintenance services at the time you purchase your new machine. Repair option programs guarantee the cost of repairs up front. Services that help optimize machine performance include:
  • Customer Support Agreements
  • S•O•SSM and Coolant Sampling and Technical Analysis
  • Maintenance contracts
  • Scheduled technical inspections
Unmatched Product Support
You will find nearly all parts at our dealer parts counter. Cat dealers use a world-wide computer network to find in-stock parts to minimize machine downtime. Save money with genuine Cat Remanufactured parts. You receive the same warranty and reliability as new products at a cost savings of 40-70 percent.
