Spacious working environment for all day comfort.

Superior Comfort

The ergonomic, automotive style operator station helps you work comfortably and productively all day long. Select the configuration that meets your needs - Canopy or Deluxe Cab with air conditioning. Features include:

  • Adjustable air suspension seat (standard)
  • Excellent visibility over the hood
  • Easy-to-read gauge cluster
  • Ample legroom
  • Automatic Engine Speed Control to conserve fuel
  • Storage compartments for tools and belongings

Ride Control

The standard Ride Control System smoothes the ride in all conditions, including load and carry, highway roading or simply moving around the job site. The result is increased operator comfort, reduced operator fatigue and improved material retention.

Pattern Selector

The pattern selector switch, located in the cab, lets you change from an excavator to a backhoe control pattern simply by pressing a button. This lets you use the pattern you are most comfortable with so you can be more productive. (Standard on pilot control machines.)

Joystick Controls

Ergonomic excavator-style joystick controls provide precise control with low effort. Thumb rollers provide convenient, fingertip control of auxiliary functions, eliminating floor mounted foot pedals.

Built for performance, power and fuel efficiency.

Cat Engine

The Cat C4.4 ACERT™ engine provides cleaner, quieter operation while delivering superior performance and durability. The engine meets U.S. EPA Tier 4 Interim and EU Stage IIIB emission requirements. The engine also features:

  • Passive regeneration system requiring no operator interaction
  • Long life diesel particulate filter
  • Improved fuel efficiency
  • Increased horsepower delivers greater pushing power, increased aggressiveness in hard bank and faster roading.


The standard auto-shift transmission matches gear with grade and load conditions. At the touch of a switch, manual mode gives the operator control over gear selection, as a power shift transmission.

  • Hydraulic proportional control valves deliver smooth speed and directional shifts.
  • Standard Four Wheel Drive (4WD) improves mobility and loader performance in poor underfoot conditions and can be activated on-the-go.
  • Maximum roading speed of 40 km/h (25 mph) improves travel time between job sites.

Brake Mode Selector

Brake mode selector switch is standard on the 450F and has three positions: two wheel drive, two wheel drive with all wheel braking and four wheel drive. Two wheel drive with all wheel braking provides better tire life while roading and engages the front axle when brakes are applied for improved braking performance.

Load-sensing system matches power to demand.

Powerful Hydraulic System

The load-sensing, closed center hydraulic system matches pressure and flow to the job demands. Whether you’re in full trenching mode or digging around delicate services, you are in control. In applications such as production trenching where speed is important, the system will provide the flow needed to get the job done quickly and efficiently. New electronic pump torque limiter delivers improved power management and hydraulic performance. The load-sensing hydraulic system also delivers:

  • Better fuel efficiency
  • Quieter operation
  • Reduced wear on components
  • Cooler hydraulic temperatures
  • Full dig and lift forces at any engine speed

Superior digging forces.


The excavator-style boom is built for optimum performance and durability. The curved design provides added clearance when digging over obstacles or loading trucks. The narrow boom enhances the viewing area to the bucket and the trench throughout the operating range. More robust swing casting and double clevis design improves durability and reliability.


Serrated edges on the stick provide improved material clamping for clearing and demolition applications. The optional extendible stick (E-stick) increases reach and dig depth by approximately 1.2 m (4 ft).


Thumb mounting provisions are standard on every Cat Backhoe Loader for added machine versatility. Cat hydraulic thumbs are available for increased versatility. Mechanical thumbs are also available through your Cat dealer.

Choice of loader linkage.

Single Tilt Loader Linkage

Single tilt loader linkage features strong lift and breakout forces for solid performance in backfilling and truck loading applications with pin-on buckets.


The return-to-dig system reduces loading cycle times by bringing the loader bucket back to the dig position with an easy pull of the lever. By the time the loader bucket is at ground level, the bucket is angled correctly for the next load or cut.

Do more jobs with one machine.

Backhoe Work Tools

Increase the versatility of your machine with the large selection of backhoe attachments:

  • Buckets - Heavy Duty and Ditch Cleaning
  • Hammers
  • Thumbs (mechanical and hydraulic)
  • Vibratory Plate Compactors
  • Quick Couplers

Loader Work Tools

A wide range of loader attachments is available including:

  • Buckets - General Purpose and Multi Purpose
  • Flip Over Forks

Lift Eyes

Integral lifting eyes are a standard feature, one on the backhoe linkage and two lifting eyes on the rear of every loader bucket.

Backhoe Quick Coupler

Quick couplers allow for quick attachment of buckets and other work tools.

Easy maintenance helps keep your machine working.

Minimize Your Downtime

Convenient service features makes maintenance easy, reducing your downtime:

  • Tilt up hood provides easy, convenient access to all engine check points
  • Electronic control module stores fault codes for easy, efficient troubleshooting and maximum machine uptime
  • Cat Product Link system (optional) provides remote reporting of machine location and operating system parameters

Unmatched support makes the difference.
