Operator Station

Unmatched Comfort

The ergonomic, automotive style operator station helps you work comfortably and productively all day long. Choose the configuration that meets your needs – Canopy, Cab Deluxe or Cab Deluxe with Air Conditioning. Other features include:

  • Adjustable air suspension seat
  • Tilt and telescoping steering column
  • Excellent visibility over hood and up to bucket dump
  • Pantograph windshield wiper
  • Large front windshield screen
  • Large LCD gauge cluster screen
  • Ample legroom
  • Optional heated seat
  • Differential lock button on loader lever
  • Large opening windows
  • Solid roof cab
  • LED brake lights
  • Heated seat (optional)
Ride Control

The optional Ride Control System smoothes the ride in all conditions, including load and carry, highway roading or simply moving around the job site. The result can be increased operator comfort, potentially reducing 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.

Premium Gauge Cluster

Bright and large LCD screen makes it easy to monitor machine operation and settings. LED indicator lights and audible alarms allow the machine to clearly communicate with the operator.

Safety Getting in and out of the Cab

New longer grab handles and ergonomic step placement makes it easy to maintain three points of contact when getting in and out of the cab.

Joystick Controls

Cat Backhoe Loader joysticks are economically designed to provide precise control with low effort. Loader control levers on both the Single Tilt and Integrated Toolcarrier models offer a thumb roller for any 3rd function auxiliary. The differential lock control is newly located on the loader control to bring controllability to the operator's fingertips. New on the IT model is the forward, neutral, reverse control switch.

Power Train

Cat Engine

The Cat C4.4 ACERT engine operates quietly while delivering performance and durability. The engine meets U.S. EPA Tier 4 Final emission standards. Engine features includes:

  • Selective catalytic reduction
  • Diesel oxidation catalyst
  • Diesel exhaust fluid with system purge
  • Limited operator interaction

The standard power shuttle transmission provides four speeds forward and reverse. Hydraulically shifted clutches allow on-the-go direction and travel speed shifts. The optional auto-shift transmission matches gear with grade and load conditions. Now with six forward and reverse speeds, the machine can reach top speeds smoothly and quickly.

  • The new optional lock-up torque converter, offered on the autoshift transmission, improves fuel efficiency up to 20% over the standard six gear autoshift. The lock-up torque converter also improves roading for long distances and with uphill climbs.
  • Hydraulic proportional control valves deliver smooth speed and directional shifts.
  • Four Wheel Drive option 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 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. Brake mode selector is included in the 4WD package.

Advanced Hydraulics

Load Sensing Hydraulics

Closed center hydraulic system matches pressure and flow to application demand. Whether you're in full trenching mode or digging around delicate services, you remain 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. The load sensing hydraulic system provides:

  • Better fuel efficiency
  • Electronically controlled
  • Quieter operation
  • Reduced component wear
  • Cooler hydraulic temperatures
  • Full forces at any engine speed
Flow Sharing Valves

Specifically tuned hydraulic valves allows for the multifunction of hydraulic components, without machine manipulation. Hydraulic fluid is shared between implements so that operation isn't interrupted.

Hydraulic Lines

Combination two way and one way flow hydraulic lines add versatility to the machine. By simply changing the lever position, the machine can efficiently run either style hydro mechanical tool.

Economy Mode

Cat Backhoe Loaders are able to reduce engine speed to 1,900 rpm while maintaining superior hydraulic power and performance.

Backhoe Performance


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).

Programmable Auxiliary Flow Control
  • Three auxiliary settings for two auxiliary functions
  • Accessed through the gauge cluster, operators can match the hydraulic flow of the machine to a work tool attachment

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

Loader Performance

Front loader arms deliver more reach, dump height and breakout. Choose the loader linkage that suits your application:

Powerful Single Tilt Loader Linkage
  • Delivers strong lift and breakout forces for a solid performance in backfilling and truck loading applications with pin-on buckets.
  • Optional third function hydraulics are now operated by an ergonomically designed thumb roller.
  • The operator can now engage the differential lock with a press of a button on the loader lever for added machine control.

Integrated Toolcarrier (IT) loader linkage (optional) provides high breakout forces with parallel lift for efficient loading and material handling:

  • The versatile integrated toolcarrier comes with a standard hydraulic quick coupler and can use a wide range of Cat Work Tools for a variety of applications.
  • The single lever IT loader control provides fine modulation of hydraulic work tools. A thumb roller operates auxiliary hydraulic functions on work tools such as multi purpose buckets, brooms and other attachments.
  • The IT loader lever provides additional machine control by offering the Forward, Neutral and Reverse control switch at the operator's fingertips.
